      Student Loan NZ — How Long Will It Actually Take to Pay Off?

      Date: 20/05/2026

      Author: Luca Tariciotti

      In New Zealand, paying off a typical student loan takes around 6 to 8 years depending on your salary, but heading overseas without a plan can drag this out for over a decade and cost you thousands in interest. Understanding exactly how the Inland Revenue Department (IRD) calculates your mandatory deductions gives you the power to project your debt-free date, allowing you to decide if making voluntary extra payments is actually a smart move for your financial future.

      If you have ever stared at your payslip and wondered where a good chunk of your hard-earned money went, your student loan deduction is likely a major culprit. For many Kiwis, the student loan feels like an invisible tax that sits on our shoulders long after graduation. But here is the good news: because the New Zealand government structure keeps loans interest-free for residents, this is one of the most unique debts you will ever carry.

      Whether you are aiming to be debt-free before applying for a mortgage, starting a business, or planning a big move to London or Melbourne for your OE, you need to know exactly how long you will be shackled to this debt. Let’s break down the mandatory deduction rates, what happens when you leave the country, and whether or not those voluntary extra payments are actually worth it.

      How the IRD Calculates Your Mandatory Deductions in 2026

      The mechanics of paying off your student loan in New Zealand are incredibly straightforward once you understand the core formula. As long as you are living in Aotearoa, your student loan is completely interest-free.

      Repayments are calculated based on your income, not the total size of your loan. According to the Inland Revenue Department (IRD), for the 2026 tax year, the student loan repayment threshold remains locked at $24,128 per year (which breaks down to $464 per week or $928 a fortnight).

      If you earn under this threshold, you do not have to make any mandatory repayments. But for every single dollar you earn above that $24,128 threshold, the IRD mandates a strict 12% deduction.

      Let’s look at a few practical, real-world New Zealand dollar examples:

      • The $60,000 Salary: Your income is $35,872 above the $24,128 threshold. The IRD takes 12% of that $35,872, meaning you will pay $4,304.64 toward your loan over the year (about $82.78 per week).
      • The $85,000 Salary: Your income is $60,872 above the threshold. At 12%, you are paying $7,304.64 per year (roughly $140.47 a week).
      • The $110,000 Salary: Your income is $85,872 above the threshold. At 12%, your mandatory repayment is $10,304.64 per year (about $198.16 per week).

      Because the threshold is frozen for 2026, any pay rise you get will immediately result in more of your take-home pay being diverted to the IRD for your student loan.

      The Math: How Long Will It Actually Take to Pay Off?

      To figure out how long it will take to clear your balance, simply divide your total loan amount by your yearly mandatory repayment amount. As your salary increases throughout your career, your repayment speed accelerates automatically. This is why many Kiwis find that their loan slowly chips away in their early twenties, but suddenly disappears rapidly once they hit their peak earning years.

      To give you a clearer picture, here is a breakdown of how long it takes to pay off a standard $40,000 student loan at various income levels in 2026, assuming your salary remains static:

      Annual Salary (NZD)Income Above ThresholdYearly Student Loan Repayment (12%)Time to Pay Off $40,000 Loan
      $50,000$25,872$3,104.6412.9 Years
      $65,000$40,872$4,904.648.1 Years
      $80,000$55,872$6,704.645.9 Years
      $95,000$70,872$8,504.644.7 Years
      $110,000$85,872$10,304.643.8 Years
      $130,000$105,872$12,704.643.1 Years

      Note: This table assumes you are a New Zealand resident for tax purposes, your loan remains interest-free, and you have a single source of income.

      The Overseas Trap: Interest Rates and Obligations

      Everything changes the moment you pack your bags for a standard Overseas Experience (OE) or a permanent move to Australia or further abroad. If you leave New Zealand for more than 183 consecutive days (about six months), you become an “overseas-based borrower.”

      The two massive financial changes are:

      1. You are charged interest. For the 2026-2027 tax year, the annual interest rate applied to overseas borrowers is hovering around 5.6%.
      2. Your repayments are based on your loan balance, not your income. The IRD does not care if you are making £80,000 in London or pouring pints in a Melbourne pub for minimum wage. When you are overseas, your mandatory minimum repayments are fixed based on how much you owe.

      For example, if your loan is between $15,000 and $30,000, you are legally required to pay $2,000 per year (usually split into two instalments due in September and March). If your loan is between $30,000 and $45,000, your mandatory repayment jumps to $3,000 per year.

      The Danger of the Minimum Payment

      If you have a $40,000 student loan and move to Australia, you are required to pay $3,000 a year. However, at a 5.6% interest rate, your loan is silently racking up $2,240 in interest over those 12 months. This means out of your $3,000 mandatory payment, only $760 is actually touching the principal debt. If you only pay the minimum, a $40,000 loan will take decades to clear and cost you thousands in interest.

      If you are moving overseas, it is absolutely crucial to make voluntary extra payments to beat the interest rate, or better yet, aggressively pay the loan down before your flight departs. You can use independent financial platforms like Sorted.org.nz to calculate exactly how much extra you need to contribute to actually pay down the principal while living abroad.

      Should I Make Voluntary Extra Payments in NZ?

      One of the most common questions young Kiwis ask is: “Should I put my spare cash toward my student loan to pay it off faster?”.

      Mathematically speaking, if you plan to stay in New Zealand, the answer is almost always no.

      Because the NZ student loan is interest-free for residents, there is zero financial benefit to paying it off early. In fact, inflation actually erodes the real value of your debt over time. Let’s say you have a spare $100 a week. You have two options:

      • Option A: You put $100 extra into your student loan as a voluntary payment. You pay off your debt faster, but you earn zero return on that money.
      • Option B: You put $100 a week into a high-interest savings account (currently yielding around 5%) or increase your KiwiSaver contributions. Over five years, that $100 a week grows exponentially thanks to compound returns.

      Financially, keeping the cash and investing it is the smarter move. The only exception to this rule is if the debt is causing you severe mental stress, or if you are planning to move overseas and want to avoid the upcoming 5.6% interest penalty. In those specific scenarios, throwing extra cash at the IRD makes perfect sense.

      Secondary Tax and Your Student Loan

      Taking on a side hustle, weekend gig, or a second job is a fantastic way to accelerate your financial goals, but you need to be prepared for how the IRD treats your secondary income.

      When you have a primary job that pays over the $24,128 threshold, your main employer is already accounting for your tax-free threshold. This means your second job will use a secondary tax code—usually STC, ST, or CAE depending on your total income bracket.

      Crucially, because your first job has already used up your student loan repayment threshold, every single dollar you earn at your second job will be subjected to the 12% student loan deduction.

      For example, if you earn $200 a week bartending on the weekends as a second job, you will immediately lose $24 of that to your student loan, on top of your standard PAYE tax. It can make a second job feel less rewarding in the short term, but the silver lining is that it aggressively speeds up your debt-free date.

      What If I Become a Contractor or Self-Employed?

      If you decide to leave the traditional 9-to-5 grind and become a sole trader, freelancer, or contractor, your student loan obligations do not disappear. However, the way you pay them changes completely.

      When you are an employee, your boss handles the PAYE and student loan deductions before the money even hits your bank account. When you are self-employed, you are entirely responsible for calculating and paying your own 12% student loan deduction on your net profit (your income minus your business expenses) at the end of the financial year.

      This can catch many new contractors off guard. If your contracting business makes $80,000 in profit, you will suddenly owe the IRD a lump sum of roughly $6,700 just for your student loan when tax time rolls around. It is absolutely critical to set aside 12% of all your earnings above the $24,128 threshold into a separate bank account throughout the year so you aren’t hit with a massive, unexpected tax bill in March.

      Does a Student Loan Affect Buying a House?

      Yes, significantly. A very common misconception is that because the loan is interest-free, banks do not care about it. In reality, New Zealand banks care heavily about your cash flow and your uncommitted monthly income when assessing your home loan application.

      When reviewing your mortgage application, banks adhere strictly to regulations set by the Reserve Bank of New Zealand (RBNZ), including Loan-to-Value Ratios (LVR) and Debt-to-Income (DTI) restrictions. Your student loan negatively impacts your mortgage application in two main ways:

      1. Reduced Servicing Ability: Because 12% of your income above the threshold is diverted straight to the IRD, you have less take-home pay available. Banks stress-test your mortgage application at interest rates much higher than the current market rate. Having 12% of your income already locked up makes it harder to pass these rigorous stress tests.
      2. Debt-to-Income (DTI) Ratios: Under the RBNZ DTI rules, your total debt (which includes your student loan, credit cards, car loans, and the proposed mortgage) cannot exceed a certain multiple of your gross income. A large student loan eats directly into the total amount of debt you are allowed to take on, meaning it directly lowers your maximum borrowing power for a property.

      Nearing the Finish Line: Don’t Overpay

      When your student loan balance drops below a few thousand dollars, you need to pay close attention to your payslips. Your employer’s payroll software does not automatically know your total loan balance; it simply continues to blindly deduct 12% of your pay based on your declared tax code.

      If your balance is $500, but your standard pay cycle deducts $300 a fortnight, you will overpay your loan in less than a month. To avoid giving the government an interest-free loan of your own money, you can apply for a Special Deduction Rate (SDR) through your myIR account when you are very close to paying it off.

      Once the loan hits zero, you must inform your employer immediately to change your tax code (usually from “M SL” to just “M”) so you can finally enjoy that extra cash in your take-home pay. Do not assume the IRD will automatically notify your boss—it is your responsibility to update your tax code paperwork.

      Frequently Asked Questions

      What is the current NZ student loan repayment threshold?

      For the 2026 tax year, the repayment threshold is $24,128 per year (or $464 per week). You do not pay anything if you earn under this amount, but you will pay 12% on every dollar earned above it.

      Does my student loan affect my ability to get a mortgage in NZ?

      Yes. While banks do not charge interest on your student loan, they factor it in when calculating your debt-to-income (DTI) ratio and your uncommitted monthly income. Because 12% of your income above the threshold is taken by the IRD, banks see this as less money available to service a mortgage, which will slightly reduce your maximum borrowing power.

      Do I pay interest on my student loan?

      If you live in New Zealand for more than 183 days a year, your student loan is completely interest-free. If you move overseas for longer than six months, interest is applied. For the 2026-2027 tax year, the overseas interest rate is 5.6%.

      Can I stop my student loan deductions if I need extra cash?

      Generally, no. The 12% deduction is a strict legal requirement. The only way to stop deductions is if your income drops below the $24,128 threshold, or if you apply directly to the IRD for a significant financial hardship exemption, which is assessed on a strict case-by-case basis.

      What happens if I forget to pay my minimums while overseas?

      The IRD applies steep penalties. On top of the standard 5.6% interest, late payment interest is currently set at 9.6% annually for the 2026 tax year. This will cause your debt to spiral rapidly, and the IRD can even stop you from leaving New Zealand at the border if your defaults are significant enough.

    • Secondary Tax in NZ — Everything You Need to Know for Your Second Job

      Secondary Tax in NZ — Everything You Need to Know for Your Second Job

      Date: 19/05/2026

      Author: Luca Tariciotti

      Secondary tax isn’t a penalty rate; it’s simply the normal PAYE system applying your correct top tax bracket to your second job so you don’t end up with a massive tax bill at the end of the year. With the cost of living pushing many Kiwis to pick-up side hustles, weekend shifts, or freelance work, understanding how your extra income is taxed ensures every dollar you earn actually moves you forward.

      Let’s break down how secondary tax codes work in New Zealand, clear up the biggest misconceptions, and help you figure out exactly what code to give your employer.

      The Biggest Myth About Secondary Tax in NZ

      If you talk to anyone in the lunchroom about getting a second job, you’ll inevitably hear someone say: “Don’t bother, the secondary tax will take half your wages.” This is the single biggest misconception about secondary tax in New Zealand.

      Secondary tax is not a penalty. The Inland Revenue Department (IRD) does not punish you for working two jobs. New Zealand operates on a progressive tax system, which means your income is taxed in layers (brackets). As your overall income increases, only the dollars that fall into the higher brackets are taxed at a higher percentage.

      When you get a second job, your primary employer has already used up your lower tax brackets (like the 10.5% and 17.5% layers). Therefore, your secondary employer needs to tax your second income at your “marginal” tax rate—the highest rate that applies to your total combined annual income. If they didn’t do this, you would underpay tax all year and receive a giant, painful bill from the IRD come April.

      2026 NZ Income Tax Brackets Refresher

      To understand secondary codes, you first need to understand the standard tax brackets for the 2025/2026 tax year:

      • 10.5% on income up to $15,600
      • 17.5% on income from $15,601 to $53,500
      • 30% on income from $53,501 to $78,100
      • 33% on income from $78,101 to $180,000
      • 39% on income over $180,000

      Your main job (using an M or ME tax code) automatically accounts for these progressive layers. Your second job needs a specific code to pick up right where your main job leaves off.

      How to Find Your Secondary Tax Code

      Your secondary tax code is based entirely on your estimated total annual income from all sources. Here are the standard secondary tax codes for New Zealand employees:

      • SB: Use if your total expected income is $15,600 or less. (Taxed at 10.5%).
      • S: Use if your total expected income is between $15,601 and $53,500. (Taxed at 17.5%).
      • SH: Use if your total expected income is between $53,501 and $78,100. (Taxed at 30%).
      • ST: Use if your total expected income is between $78,101 and $180,000. (Taxed at 33%).
      • SA: Use if your total expected income is over $180,000. (Taxed at 39%).

      (Note: If you have a New Zealand Student Loan, you simply add “SL” to your code, such as S SL or SH SL. This tells your employer to deduct the mandatory 12% student loan repayment from your secondary income).

      Real NZ Dollar Examples

      Let’s look at how this plays out in the real world with some NZD examples.

      Example 1: The Part-Time Hustle Mark works part-time at a local supermarket, earning $35,000 a year. He decides to pick up a second part-time job at a hardware store, which will pay him roughly $10,000 a year.

      • Main Job: $35,000 (Uses code M)
      • Second Job: $10,000
      • Total Expected Income: $45,000 Because his total income ($45,000) falls into the $15,601 to $53,500 bracket, Mark will give the hardware store the S tax code. His hardware store earnings will be taxed at a flat 17.5%.

      Example 2: Pushing into a Higher Bracket Jane is a graphic designer earning $70,000 a year at her primary agency. She decides to work weekends managing social media for a local cafe, which pays her $15,000 a year.

      • Main Job: $70,000 (Uses code M)
      • Second Job: $15,000
      • Total Expected Income: $85,000 Because her total combined income ($85,000) pushes past the $78,100 threshold, she falls into the 33% tax bracket. Jane must use the ST tax code for her cafe job. Every dollar she earns at the cafe will be taxed at 33%.

      Special Tax Codes: STC and CAE

      Sometimes, the standard secondary codes don’t perfectly fit your situation. That’s where special codes come in.

      1. Tailored Tax Code (STC) If you think your secondary tax code will result in you overpaying tax during the year (for example, if your second job only pushes your total income slightly into the next tax bracket, rather than fully), you can apply for a Tailored Tax Code directly through the IRD. Formerly known as a Special Tax Code (STC), this allows the IRD to calculate a custom percentage for your secondary employer to deduct, ensuring your PAYE is perfectly balanced.

      2. Casual Agricultural Worker (CAE) If you are doing casual, seasonal agricultural work (like fruit picking, shearing, or shed-handling) for up to 3 months, you use the CAE tax code. This taxes your earnings at a flat rate of 17.5%, plus ACC levies.

      Contractor vs Employee NZ: How It Affects Your Second Job

      Often, picking up a second stream of income isn’t about finding a second employer—it’s about freelancing or starting a small business. You might be weighing the debate of contractor vs employee NZ and asking yourself: should I go contracting NZ for my side hustle?

      If you choose to be an employee, everything is handled for you via the PAYE system and the secondary codes we just discussed. Your employer deducts your tax, ACC, and KiwiSaver before the money hits your bank account.

      If you choose to be a contractor, the rules change:

      • Tax Codes: You won’t use S, SH, or ST codes. Instead, you’ll generally use the WT (Withholding Tax) tax code for Schedular Payments. The tax rate deducted depends on your specific industry (often ranging from 10% to 20%), but this is only a pre-payment.
      • Your Responsibilities: As a contractor, you are running your own business. You are responsible for paying your own ACC levies, setting aside money for your student loan, and managing your own KiwiSaver contributions.
      • Expenses: The major benefit of contracting is that you can claim business expenses (like home office costs, software, or travel) against your contracting income, which lowers your overall taxable income.

      Whether you should go contracting in NZ depends heavily on how comfortable you are with accounting, managing your own cash flow, and setting aside money for the IRD at the end of the financial year.

      What Happens If You Get Your Code Wrong?

      If you accidentally give your secondary employer the wrong tax code, one of two things will happen:

      1. You Overpay: If you give a code that taxes you at 33% (ST), but your total income actually keeps you in the 17.5% bracket, you will overpay tax every payday. The good news? The IRD automatically calculates this at the end of the tax year (March 31) and will issue you a tax refund between May and July.
      2. You Underpay: If you give a code that taxes you at 17.5% (S), but your total income pushes you into the 30% bracket, you will underpay tax. At the end of the tax year, the IRD will calculate the shortfall and send you a bill that you are legally required to pay.

      Always estimate your total income cautiously. It is far better to slightly overpay and get a nice refund in the winter than to underpay and scramble to find cash to pay the taxman.

      Frequently Asked Questions

      1. Do I get taxed more heavily just because I have a second job? No. You are taxed on your total income. Earning $60,000 from one job results in the exact same amount of total tax as earning $40,000 from your main job and $20,000 from a second job. The secondary tax code just ensures the correct rate is applied to your top-up income.

      2. How do I change my secondary tax code if my income drops? If your primary salary drops or you reduce your hours, your total estimated income might fall into a lower bracket. Simply fill out a new Tax Code Declaration (IR330) form, hand it to your secondary employer, and they will update your code in their payroll system.

      3. Do I need a secondary tax code if I’m a sole trader/contractor? If you are invoicing clients directly as a sole trader (not receiving schedular payments), you do not use secondary tax codes like SH or ST. You receive the full gross amount from your clients and must calculate, declare, and pay your own income tax at the end of the year via an IR3 tax return.

      4. What code do I use if both my jobs pay exactly the same amount? You can only have one “main” job. Choose whichever job you have held the longest, or whichever is most stable, and assign that the M code. Give the other job the appropriate secondary code based on your combined total income.

    • Contractor vs Employee in NZ — The Real Financial Difference

      Date: 18/05/2026

      Author: Luca Tariciotti

      If you are weighing up being a contractor vs employee in NZ, you might think jumping from a $100k salary to an $80-an-hour rate is an instant ticket to wealth. But once you strip away the hidden costs of unpaid leave, ACC levies, and business expenses, the real financial difference is much smaller than it appears.

      With the cost of living in Wellington and Auckland remaining high in 2026, many Kiwis are looking for ways to maximize their income. The allure of contracting is undeniable. You set your own hours, you can pick and choose your clients, and the hourly rates look incredibly high compared to a standard PAYE salary. But there is a massive difference between what you invoice as a business and what you actually get to keep in your personal bank account.

      If you are currently wrestling with the contractor vs employee in NZ dilemma, you are absolutely not alone. It is one of the most common career questions we encounter. This comprehensive guide will break down exactly what that choice means for your back pocket. We are going to put two realistic scenarios head-to-head: a standard $100,000 employee salary versus an $80 per hour contractor rate. We will look at the hidden costs like holidays, insurance, accounting software, and what happens to your KiwiSaver.

      By the end of this guide, you will know exactly whether you should go contracting in NZ, or if the safety and perks of the standard PAYE system are the better bet for you.

      The Legal and Practical Differences

      Before we dive into the spreadsheets and crunch the numbers, it is crucial to understand how New Zealand employment law and the Inland Revenue Department (IRD) view these two very different ways of working. You cannot simply call yourself a contractor to pay less tax; there are legal definitions you must meet.

      The Employee (The PAYE Safety Net)

      When you are an employee, you operate under an employment agreement covered by the Employment Relations Act. Your employer handles all the heavy lifting. They deduct your tax (PAYE), sort out your student loan repayments, manage your KiwiSaver contributions (and add their 3% minimum match), and pay your ACC earner’s levy before the money even hits your bank account.

      Most importantly, you get guaranteed statutory rights:

      • Four weeks of paid annual leave.
      • 12 statutory public holidays (including Matariki).
      • A minimum of 10 days paid sick leave per year.
      • Protection against unjustified dismissal.

      The Contractor (The Independent Hustle)

      As a contractor, you are essentially running your own business—even if you are just a sole trader. You are an independent entity providing a service to a client. You invoice them for your time or the completed project, and they pay you the gross amount (plus GST, if you are registered).

      The IRD uses specific tests to determine if you are genuinely a contractor, including the Control Test (do you have the freedom to choose how and when you work?), and the Independence Test (do you provide your own tools and work for multiple clients?).

      As a contractor, it is entirely on your shoulders to set aside money for tax, pay your own ACC levies, fund your own retirement, and cover all your own expenses. If you don’t work, you don’t get paid. There is zero sick leave and zero holiday pay.

      The Real Numbers: $100k Salary vs $80/hr Contractor

      To make this practical, we are going to use a real-world worked example. Let’s compare a standard $100,000 permanent employee salary with an independent contractor charging $80 an hour. At first glance, $80 an hour sounds like vastly more money. But let’s look at the reality of billable hours and necessary downtime.

      The $100,000 Employee Scenario

      If you are on a $100k salary, you are paid for 52 weeks of the year, regardless of when you take your summer holiday or if you catch a nasty winter flu.

      A standard working year is 260 days (52 weeks x 5 days, or 2,080 hours). However, because of your guaranteed time off (20 days annual leave, 12 public holidays, 10 sick days), you are effectively “at work” for only 218 days, or 1,744 hours.

      Using the 2026 NZ tax brackets (which took full effect in July 2024), here is how a $100,000 salary breaks down:

      Income & DeductionsAmount (NZD)
      Gross Income$100,000
      Income Tax-$22,877
      ACC Earner’s Levy (approx 1.39%)-$1,390
      Take-Home Pay (Before KiwiSaver)$75,733

      The Hidden Bonus: Your employer is legally required to contribute 3% to your KiwiSaver. That is an extra $3,000 (before Employer Superannuation Contribution Tax) going straight into your retirement fund every single year. According to Sorted.org.nz, this “free money” is a massive factor in long-term wealth building.

      The $80/hr Contractor Scenario

      Now let’s look at the contractor. You charge $80 an hour. If you worked 40 hours a week for 52 weeks straight, you would invoice $166,400. That sounds incredible!

      But you are human. You need a break. Let’s assume you take the exact same time off as the employee: 4 weeks of holiday, the 12 statutory public holidays, and 10 sick days.

      • Total Billable Hours: 1,744 hours
      • Gross Invoiced Income (1,744 hours x $80): $139,520

      So, the contractor brings in roughly $39,500 more in gross cash than the employee. But we haven’t deducted the expenses of running a business yet.

      The Hidden Costs of Being Your Own Boss

      When you are self-employed, a chunk of your gross income goes straight toward overheads that an employer usually covers for free. Let’s break down the realistic, conservative business expenses for our $80/hr contractor over a year:

      • Insurance: Most corporate clients will require you to hold Professional Indemnity and Public Liability insurance before you can sign a contract. Let’s estimate this at $1,200/year.
      • Accounting & Software: You’ll need software like Xero or Hnry, or an accountant to manage your taxes and file GST returns accurately. Let’s budget $1,000/year.
      • Technology & Equipment: A good laptop, software subscriptions (like Adobe or Microsoft 365), and general IT maintenance. Let’s call it $1,500/year.
      • Home Office & Connectivity: A portion of your home internet, mobile phone plan, and home office utility costs. Let’s say $1,000/year.
      • ACC Levies: Contractors pay the standard earner’s levy plus the work account levy (CoverPlus or CoverPlus Extra), which varies by industry risk. Let’s estimate $2,200/year.

      Total Estimated Expenses: $6,900/year.

      Your taxable profit is now $139,520 minus $6,900 = $132,620.

      Tax Time: IRD Brackets, Provisional Tax, and GST

      Let’s look at how the income tax shakes out for the contractor’s $132,620 taxable profit, using the standard 2026 NZ tax rates (10.5% up to $15.6k, 17.5% up to $53.5k, 30% up to $78.1k, and 33% up to $180k).

      The total income tax on $132,620 is roughly $33,640.

      Contractor Final Take-Home Math:

      • Gross Profit: $132,620
      • Minus Income Tax: -$33,640
      • Minus KiwiSaver (Matching the employee’s 3% + your own 3% to keep things even = $6,000)
      • Net Money in the Bank (After equivalent retirement savings): ~$92,980

      The Provisional Tax Trap

      If your tax bill at the end of the year is more than $5,000, the IRD will require you to pay “Provisional Tax” the following year. This means you will be paying tax in advance in three installments throughout the year, while simultaneously paying off your tax bill from your first year of contracting. Many new contractors get caught out by this double-whammy in year two. You must be disciplined in setting aside at least 30% of every invoice into a separate tax bank account.

      A Note on GST (Goods and Services Tax)

      If you earn over $60,000 in a 12-month period as a contractor, the IRD requires you to register for GST. This means you must add 15% to your hourly rate. If your rate is $80/hr, you will actually invoice $92/hr ($80 + GST). You collect that extra $12 and hold it, then pass it on to the IRD every 1, 2, or 6 months. It is not your money, so never spend it.

      As a contractor, you miss out entirely on the 3% employer KiwiSaver match, because you are your own employer. However, you can (and should) make voluntary contributions. As long as you personally contribute at least $1,042.86 before June 30th each year, you still qualify for the annual Government contribution of up to $521.43.

      If you have a New Zealand Student Loan, employees have a flat 12% deducted from their pay for anything earned over the repayment threshold (currently $24,128 per year). As a contractor, this isn’t deducted automatically. You must calculate this 12% on your net profit above the threshold and pay it directly to the IRD at the end of the tax year. Failing to budget for this is a common mistake that leads to massive unexpected tax bills.

      The “Risk Premium”: How Much Should You Charge?

      Looking at the numbers above, the contractor clears around $92k (after funding their own retirement and business expenses), while the employee clears around $75k (but gets employer KiwiSaver on top). The contractor is financially ahead, but only by roughly $15,000 to $17,000 a year.

      Is $15,000 enough of a reward for the extra stress? That is what we call the Risk Premium.

      When you ask, “should I go contracting NZ?”, you have to factor in the risks the math doesn’t show:

      • Job Insecurity: A contractor can usually be let go with zero to two weeks’ notice. If the economy tightens, as seen in recent RBNZ updates, contractors are often the first overhead businesses cut.
      • Bench Time: We assumed you work 1,744 billable hours. But what if it takes you a month to find your next contract? That’s roughly $13,000 in lost revenue.
      • Admin Time: You will spend unpaid hours chasing late invoices, filing taxes, and finding new clients.

      The Golden Rule of Contracting: A common rule of thumb in New Zealand is that your hourly contracting rate needs to be at least your desired salary divided by 1,000 (or 1,200 at a stretch) to break even on the risk and expenses. So, to match a comfortable $100k salary lifestyle with all its protections, an $80 to $100 hourly rate is exactly where you need to be.

      Ultimately, if you are highly disciplined with money, have an in-demand skill set, and value flexibility over predictability, contracting can be highly lucrative. If you value security, easy mortgage approvals, and paid sick leave, stick with PAYE.

      Frequently Asked Questions

      What is the difference between a contractor and an employee in NZ?

      An employee has a legal employment agreement, receives guaranteed pay, paid leave, and job security. Their employer handles tax, ACC, and KiwiSaver. A contractor is self-employed, runs their own business, invoices for their time, handles their own taxes and expenses, and receives no paid leave or job security.

      Do contractors pay ACC in New Zealand?

      Yes, contractors actually pay more in ACC than employees. While employees only pay the Earner’s Levy (deducted via PAYE), contractors must pay the Earner’s Levy plus a Work Account levy (CoverPlus), which covers workplace injuries. The rate depends on the risk level of your specific industry.

      Can a contractor get KiwiSaver in NZ?

      Contractors can voluntarily contribute to KiwiSaver. However, you do not receive the 3% employer match, because you are your own employer. You are still eligible for the annual Government contribution (up to $521.43) as long as you personally contribute at least $1,042.86 before June 30th each year.

      How much extra should a contractor charge compared to an employee?

      A standard NZ rule of thumb is to take the annual permanent salary you want and divide it by 1,000. For example, to comfortably match a $100,000 salary with its benefits and absorb the risks of unpaid downtime and business expenses, you should aim to charge around $100 per hour (or at minimum $80/hr).

      What expenses can I claim as a contractor in NZ?

      You can claim expenses directly related to generating your income. Common deductions include accounting fees, professional insurance, a portion of your home office costs (power, internet, rent/mortgage interest based on floor space), mobile phone bills, and travel expenses to client sites (excluding your normal daily commute).

    • How to Calculate Your Take-Home Pay in NZ (PAYE, ACC, KiwiSaver Explained)

      Knowing exactly how much lands in your bank account on payday helps you budget better and figure out how much you can really afford for a mortgage, rent, or those shared flatmate expenses. With the cost of living across New Zealand climbing, understanding the difference between your gross salary and your actual take-home pay after PAYE, ACC, and KiwiSaver is crucial for your daily financial survival.

      Introduction

      Kia ora! We’ve all been there: you sign an employment contract for a shiny new salary, say $80,000, and you feel on top of the world. But when that first payday rolls around and you check your banking app, the number hitting your account looks a lot smaller than you expected. Where did it all go?

      Whether you are trying to budget for your weekly Pak’nSave run, save up for a first home deposit, or you just want to figure out “how much tax do I pay in NZ?”, you need to understand the mechanics of your payslip. Specifically, you need to understand the “Big Three” deductions that are stripped out of your paycheck automatically: PAYE (income tax), the ACC earners’ levy, and your KiwiSaver contributions.

      In New Zealand, the Inland Revenue Department (IRD) system is designed to take these deductions out before you even see the money. That’s great for convenience—you rarely have to worry about a massive, unexpected tax bill at the end of the financial year—but it can make it incredibly confusing to know exactly what your true take-home (net) pay is.

      To clear up any confusion regarding old tax years, we are going to break down every single deduction line by line using the absolute latest April 1, 2026 legislative updates. We will use real New Zealand dollar examples for $60,000, $80,000, and $100,000 salaries so you know exactly where your hard-earned money is going in the current financial landscape.

      1. PAYE Income Tax: How New Zealand’s Tax Brackets Actually Work

      PAYE stands for “Pay As You Earn.” It is exactly what it sounds like: as you earn money on your hourly wage or salary, your employer calculates a slice of it and sends it directly to the IRD on your behalf.

      A massive misconception in New Zealand is how our tax brackets actually work. We use a progressive tax system. This means that as you earn more, you do not pay the highest tax rate on all of your money. You only pay the higher rate on the money that falls into that specific tier.

      Think of it like filling up a series of water buckets. The IRD only takes a 10.5% scoop out of your first bucket. Once that bucket overflows into the next, they take a slightly larger 17.5% scoop out of the second bucket, and so on.

      Here are the official, current IRD tax brackets for the 2026 tax year:

      Income RangeTax Rate
      $0 to $15,60010.5%
      $15,601 to $53,50017.5%
      $53,501 to $78,10030%
      $78,101 to $180,00033%
      $180,001 and over39%

      Let’s look at a real-world example of marginal tax:

      If you get a promotion that pushes your salary from $75,000 to $80,000, you don’t suddenly pay 33% tax on your entire $80,000 salary. You still pay the lower 10.5%, 17.5%, and 30% rates on the bottom chunks of your income. You only pay the 33% rate on the final $1,900 that “spills over” the $78,100 threshold.

      This means a pay rise is always a good thing. You will never take home less money just because you jumped into a higher tax bracket!

      2. The ACC Earners’ Levy: Your Built-In Insurance

      Next up on your payslip is the ACC levy. The Accident Compensation Corporation (ACC) is New Zealand’s unique, no-fault accidental injury scheme. It covers your medical bills, rehabilitation, and up to 80% of your lost wages if you get injured—whether you’re hurt on a construction site in Auckland, or you simply roll your ankle playing weekend social netball in Wellington.

      Because every single person in the country benefits from this safety net, every working Kiwi chips in to fund it through the ACC earners’ levy.

      The April 2026 Update:

      As of April 1, 2026, the ACC earners’ levy increased from 1.67% to 1.75% (which works out to $1.75 per $100 you earn). It is important to note that this levy is capped. For the 2026 year, you only pay the ACC levy on earnings up to a maximum threshold of $156,641. So, the absolute maximum you will ever pay for the ACC earners’ levy in a year is $2,741.22.

      While it might feel annoying to see another chunk of money disappear from your pay before it reaches your bank, ACC is a massive nationwide safety net that prevents everyday Kiwis from going bankrupt over unexpected hospital bills.

      3. KiwiSaver: Paying Your Future Self

      The third major deduction is KiwiSaver, New Zealand’s voluntary retirement and first-home savings scheme. While technically voluntary, you are automatically enrolled when starting a new job, and staying in the scheme is universally considered one of the smartest financial moves you can make to combat the New Zealand retirement gap.

      The April 2026 Update:

      A major legislative shift occurred on April 1, 2026. The minimum default contribution rate for both employees and employers increased from 3% to 3.5%.

      This means a minimum of 3.5% of your gross pay is funneled into your chosen KiwiSaver fund. The beautiful part? Your employer is legally required to match that 3.5%. That is literally free money working for your retirement or your first home deposit. (Note: Employees can apply for a temporary rate reduction to stay at 3% if needed, but for long-term wealth, the new default is recommended).

      On top of employer matches, the government chips in an annual “Government Contribution.” Historically this was up to $521.43, though recent 2025/2026 tweaks reduced this to $260.72 for some, and removed it entirely for those earning over $180,000.

      You can choose to voluntarily contribute more to hit your goals faster (common rates are 4%, 6%, 8%, or 10%), but for our baseline take-home pay calculations below, we will assume you are on the new 2026 default rate of 3.5%.

      4. Line-by-Line Salary Breakdowns: The Real Math

      Let’s put all these theories into practice and see what happens to real New Zealand salaries.

      For the tables below, we will use the standard M tax code (which assumes this is your main job), and we will assume you have no student loan. We are utilizing the progressive 2026 tax brackets, the new 1.75% ACC levy, and the new 3.5% default KiwiSaver rate.

      Example 1: Earning $60,000 a Year

      Earning $60,000 is a common milestone for young professionals and tradespeople. Here is exactly where your money goes.

      Deduction TypeAnnual AmountNotes
      Gross Income$60,000.00Before any deductions.
      Income Tax (PAYE)-$10,220.5010.5% on first $15.6k, 17.5% on next $37.9k, 30% on final $6.5k.
      ACC Levy (1.75%)-$1,050.00Mandatory injury cover (calculated as 1.75% of $60,000).
      KiwiSaver (3.5%)-$2,100.00Invested for your future (calculated as 3.5% of $60,000).
      Net Take-Home Pay$46,629.50What you actually keep.
      • Monthly: $3,885.79
      • Fortnightly: $1,793.44
      • Weekly: $896.72

      Notice that out of a $60,000 gross salary, you are taking home around $896 a week to cover your rent, groceries, power, and lifestyle.

      Example 2: Earning $80,000 a Year

      Moving up the ladder to $80,000 pushes a tiny sliver of your income into the 33% tax bracket.

      Deduction TypeAnnual AmountNotes
      Gross Income$80,000.00Before any deductions.
      Income Tax (PAYE)-$16,277.50Includes 33% tax on the final $1,900 over the $78,100 threshold.
      ACC Levy (1.75%)-$1,400.00Mandatory injury cover.
      KiwiSaver (3.5%)-$2,800.00Invested for your future.
      Net Take-Home Pay$59,522.50What you actually keep.
      • Monthly: $4,960.20
      • Fortnightly: $2,289.32
      • Weekly: $1,144.66

      You earn $20,000 more on paper than the $60k earner, but due to the progressive tax system, your weekly take-home pay only goes up by about $247.

      Example 3: Earning $100,000 a Year

      Hitting six figures is a massive goal. At this level, a solid $21,900 chunk of your income sits in the 33% tax bracket.

      Deduction TypeAnnual AmountNotes
      Gross Income$100,000.00Before any deductions.
      Income Tax (PAYE)-$22,877.50Progressive tax up to the 33% tier.
      ACC Levy (1.75%)-$1,750.00Mandatory injury cover.
      KiwiSaver (3.5%)-$3,500.00Invested for your future.
      Net Take-Home Pay$71,872.50What you actually keep.
      • Monthly: $5,989.37
      • Fortnightly: $2,764.32
      • Weekly: $1,382.16

      Even on a $100k salary, after tax, ACC, and investing 3.5% into your KiwiSaver, your weekly household budget has just under $1,400 to work with.

      5. Got a Student Loan? (The Hidden Tax)

      If you went to university or completed a trade course and racked up a StudyLink loan, you have one more major hurdle before you get to your net pay.

      In New Zealand, student loan repayments are mandatory once you earn over the annual repayment threshold. For 2026, the threshold sits firmly at $24,128 per year (which breaks down to exactly $464 per week).

      The IRD will automatically deduct 12% of every single dollar you earn above this threshold.

      Let’s look at the math: If you earn $60,000, you are earning $35,872 above the threshold. That means an extra $4,304.64 a year ($82.78 a week) comes out of your pay before you see it. When you use an NZ take-home pay calculator, always make sure to tick the “Student Loan” box and use the M SL tax code. It makes a surprisingly large dent in your weekly cash flow!

      6. What If You Have a Second Job or Go Contracting?

      The standard calculations above are perfect if you have one main job as a traditional salaried employee. But life in NZ is rarely that simple. Cost of living often dictates side incomes.

      Working a Side Hustle?

      If you pick up weekend shifts at a cafe, do some freelance graphic design, or drive for Uber on top of your main 9-to-5, you will need to use a secondary tax code (like SB, S, SH, or ST). Many people think “secondary tax” means you are heavily penalized and arbitrarily taxed at a ridiculously high rate. You aren’t!

      Secondary tax codes simply try to accurately estimate what your total combined annual income will be across all your jobs, so you pay the correct progressive rate and don’t end up with a massive tax bill in March.

      Curious about the exact math? Check out our Secondary Tax Calculator to see exactly how your side hustle income is taxed.

      Thinking of Going Freelance?

      If you are weighing up a $100k salary versus an $80/hour contracting gig, the take-home math completely changes. Contractors do not get holiday pay, sick leave, or mandatory employer KiwiSaver matches. However, they can claim valid business expenses (like laptops, home office space, and vehicle mileage) to lower their overall taxable income.

      Run the numbers on our Contractor vs Employee Calculator to see which path actually leaves you with more cash in the bank.

      Frequently Asked Questions

      What is an NZ take home pay calculator used for?

      A take-home pay calculator (often called a PAYE calculator) does all the heavy math for you. You punch in your gross salary, select your KiwiSaver rate, and check if you have a student loan. It instantly calculates exactly how much cash will land in your bank account weekly, fortnightly, or monthly. It’s an essential tool for budgeting, planning for a mortgage, or negotiating a new salary in New Zealand.

      How much tax do I pay in NZ if I earn $70,000?

      If you earn $70,000 in 2026, your progressive PAYE income tax is $13,277.50. You will also pay $1,225 in ACC levies (at the new 1.75% rate), and if you contribute the default 3.5% to KiwiSaver, that’s another $2,450. Your total net take-home pay would be $53,047.50 for the year.

      Why did my take-home pay change in April 2026?

      Two big changes hit payrolls on April 1, 2026. First, the ACC earners’ levy increased to $1.75 per $100 (1.75%). Second, the minimum default KiwiSaver contribution rate for both employees and employers jumped from 3% to 3.5%. Both of these factors slightly reduced the immediate, in-hand take-home pay for everyday Kiwis, though the KiwiSaver bump means your employer is contributing more to your future wealth!

      Is KiwiSaver calculated before or after tax?

      KiwiSaver contributions are calculated based on your gross pay (your income before any tax is removed). If you earn $1,000 a week before tax, a 3.5% KiwiSaver deduction will be exactly $35. It is not calculated on your net pay.

      Do I really have to pay the ACC levy?

      Yes. If you are earning a salary or wage in New Zealand, the ACC earners’ levy is a mandatory, legal deduction. You cannot opt out of it. It is automatically taken out of your pay by your employer alongside your PAYE tax to fund the nationwide injury cover scheme.

    • Should I Fix or Float My Mortgage in 2026?

      Date: 15/05/2026

      Author: Luca Tariciotti

      Splitting your mortgage into a mix of fixed and floating rates is usually the smartest financial move in 2026, giving you the safety of locked-in payments while keeping the door open to smash your debt faster without paying nasty penalty fees. With the cost of living still squeezing Kiwi households from Whangārei to Invercargill, choosing the right home loan structure could literally save you tens of thousands of dollars in interest and knock years off your repayment schedule.

      The 2026 NZ Mortgage Landscape

      Welcome to the great Kiwi mortgage debate: should you fix or float your home loan in 2026? It is the question every single property owner faces, whether you have just successfully navigated a KiwiSaver first home withdrawal for a modest townhouse, or you are a seasoned investor coming up for a mortgage renewal on a family home.

      Right now, the New Zealand property market is operating in a vastly different environment than the wild peak of 2021 or the subsequent stress-test era of 2023. Following the Reserve Bank of New Zealand (RBNZ) making adjustments to the Official Cash Rate (OCR) to stabilize inflation, we are seeing wholesale rates settle. However, picking a mortgage structure is not just about hunting down the absolute lowest percentage advertised on a bank’s window. It is about understanding your household cash flow, your job security, whether you plan to take in flatmates to help with the bills, and how aggressively you want to save.

      When you are looking at fix or float mortgage NZ 2026 options, you have to consider the banking rules. Banks still enforce strict Loan-to-Value Ratio (LVR) restrictions, meaning most owner-occupiers need a 20% deposit, though there are exemptions if you qualify for a First Home Loan via Kāinga Ora. Furthermore, the new Debt-to-Income (DTI) rules mean banks are heavily scrutinizing your income compared to your total debt. Because banks will still “stress test” your ability to pay at a rate higher than the one you actually sign up for, getting your structure right is the key to proving you can manage your money.

      What Does it Mean to “Fix” Your Mortgage?

      A fixed-rate mortgage is exactly what it sounds like: you sign a contract with your bank to lock in a specific interest rate for a set period. In New Zealand, terms typically range from six months up to five years. The vast majority of Kiwis prefer fixed rates for the bulk of their borrowing because we culturally value certainty.

      The Pros of Fixing Your Home Loan

      • Rock-Solid Budgeting Certainty: You know exactly what your repayments will be every single fortnight or month. This is absolutely crucial if household funds are tight, or if you have fixed outgoing expenses like childcare, insurance premiums, or a Hire Purchase on a family car.
      • Protection Against Rate Hikes: If the RBNZ suddenly raises the OCR to combat an unexpected spike in inflation, your fixed rate will not budge until your agreed term expires. You are safely insulated from the economic storm.
      • Lower Advertised Rates: Traditionally, fixed rates are lower than floating rates in NZ. Banks offer a discount because you are committing to stay with them for a set time, providing them with a guaranteed return.

      The Cons of Fixing Your Home Loan

      • The Dreaded Break Fees: If you sell your house, win Lotto, or want to refinance to a better rate at a competing bank before your term is up, your current bank will likely charge you an Early Repayment Adjustment (break fee). These fees can easily run into thousands of dollars.
      • Limited Ability to Make Extra Repayments: Most NZ banks cap how much extra you can pay off your fixed mortgage without triggering a penalty. Usually, you are limited to increasing your regular payments slightly or making a lump sum payment of up to 5% of your total loan balance per year.

      Real NZ Dollar Example: The Fixed Rate

      Let’s say you have a $600,000 mortgage and you decide to fix the entire amount at 5.50% for two years over a standard 30-year term.

      • Your minimum fortnightly repayment will be roughly $1,565.
      • Over the 24-month fixed period, you will pay exactly $81,380 in total mortgage repayments. You can plan your entire life around that exact number. The catch? If you get a $15,000 bonus at work and want to dump it onto the mortgage to save interest, the bank might penalize you for exceeding the 5% overpayment limit.

      What Does it Mean to “Float” Your Mortgage?

      A floating rate (often called a variable rate overseas) goes up and down depending on the wider financial market and the RBNZ’s OCR decisions. The bank can change this rate at any time, usually giving you around 14 days’ notice before your minimum payment increases or decreases.

      The Pros of Floating Your Home Loan

      • Ultimate Payment Flexibility: You can make massive lump-sum payments at any time. If you get an inheritance, sell a car, or manage to aggressively save by getting flatmates to rent your spare room, you can dump that cash straight onto your mortgage without paying a single cent in break fees.
      • Offset Capabilities: Many floating mortgages can be linked to an offset account or a revolving credit facility. This is a massive advantage for disciplined savers and business owners.
      • Easy to Restructure: If you want to sell your house to upgrade, subdivide your section, or switch banks for a better cash-back deal, you can do so immediately without any exit penalties.

      The Cons of Floating Your Home Loan

      • Higher Interest Rates: Floating rates are almost always higher than short-term fixed rates. You are essentially paying a premium for the privilege of flexibility.
      • Budget Uncertainty: If NZ mortgage rates 2026 climb due to economic pressure, your required minimum repayment climbs right along with them, which can squeeze your household budget unexpectedly.

      Real NZ Dollar Example: The Floating Rate

      Take that same $600,000 mortgage, but put it entirely on a floating rate of 6.50% over 30 years.

      • Your minimum fortnightly repayment jumps to roughly $1,735 (about $170 more per fortnight than fixing).
      • However, let’s say after six months you receive a $20,000 inheritance. Because there are no penalties, that entire $20,000 goes straight toward reducing your principal loan amount. Over the life of a 30-year loan, making that single early payment could save you tens of thousands in compounded interest and shave more than a year off your total term.

      The Kiwi Compromise: Splitting Your Mortgage

      Why choose one when you can have both? For most New Zealanders, splitting your mortgage into a mix of fixed and floating is the ultimate strategy.

      By splitting your loan, you put the bulk of your debt on a lower fixed rate for stability, and leave a smaller chunk on a floating rate so you can aggressively pay it down without restriction.

      How a Split Works in Practice

      Imagine you still have that $600,000 mortgage. You could structure it like this:

      • $550,000 Fixed for 1 Year: This gives you a low rate and predictable repayments for the lion’s share of your debt. You know exactly what 90% of your mortgage will cost.
      • $50,000 Floating: You use this smaller portion to make extra payments. If you manage to save an extra $300 a fortnight by cutting back on subscriptions and takeaways, you throw it entirely at this floating chunk. Once the floating portion is paid off, you wait for your fixed term to expire, carve off another $50,000 to float, and repeat the process.

      Advanced Tactics: Offset Accounts and Revolving Credit

      When you have a floating portion, you can take advantage of specialized banking products that act as a financial superpower. These tools are heavily promoted by independent financial educators on the Sorted.org.nz website for a good reason.

      The Offset Mortgage

      An offset mortgage looks at the cash sitting in your everyday transaction accounts and savings accounts and “offsets” it against your floating mortgage balance.

      For example, if you have a $30,000 floating mortgage and $10,000 sitting in your savings account, the bank only charges you interest on the $20,000 difference. It is a fantastic way to make your emergency fund work for you without locking the money away. Plus, because you aren’t technically earning interest on that savings account (you are just saving on mortgage interest), you do not have to pay any Resident Withholding Tax on those savings to the Inland Revenue Department (IRD).

      The Revolving Credit Facility

      This acts like a massive overdraft secured against your house. Your salary goes straight into the account, immediately lowering the daily loan balance (and the interest calculated that day). You pay your power bills and buy groceries out of it as needed. Because mortgage interest in NZ is calculated daily, every day your salary sits in that account, it saves you money. However, it requires strict financial discipline—if you treat it like free money to buy a boat, you will go backwards quickly.

      How to Avoid the Dreaded Break Fee

      One of the biggest fears Kiwis have when fixing a mortgage is the break fee.

      When a bank lends you money on a fixed rate, they secure that funding on the wholesale market for that exact time frame. If you pay them back early, and wholesale interest rates have dropped since you originally fixed the loan, the bank loses money. The break fee is legally designed to cover their financial loss.

      In a falling interest rate environment, breaking a high fixed rate to jump onto a new, lower 2026 rate might seem tempting. However, the break fee is mathematically calculated to wipe out the exact savings you would make by switching to the lower rate with that same bank.

      Breaking only usually makes financial sense if:

      1. You are selling the property and have no choice.
      2. You are switching to a completely different bank that is offering a massive cash-back incentive to move your business, which covers the entire cost of the break fee.
      3. You suddenly have a massive lump sum of cash (like a property sale) and the break fee is less than the interest you would save by paying off the principal immediately.

      Before breaking, always ask your bank for a definitive break fee quote—they change daily based on wholesale swap rates.

      Frequently Asked Questions

      Do NZ banks charge fees to switch from floating to fixed?

      Usually, no. If you are on a floating rate, you can “lock in” a fixed rate at any time without paying a break fee. This is why some Kiwis let their fixed rate expire, roll onto a floating rate for a few weeks while they assess the market, and then re-fix when they spot a good deal.

      How much extra can I pay on a fixed mortgage without fees?

      Most major New Zealand banks allow you to increase your regular repayments or make lump-sum payments up to 5% of your initial loan balance per year without triggering a penalty. Always check your specific loan contract, as policies vary between ANZ, BNZ, Westpac, ASB, and Kiwibank.

      Is an offset mortgage the same as floating?

      An offset mortgage is a type of floating mortgage. The interest rate is typically the standard floating rate, but you have the added benefit of using your everyday savings balances to offset the principal amount that accrues daily interest.

      Should First Home Buyers fix for 1 year or 5 years?

      In 2026, shorter terms like 1-year to 18-months remain highly popular. Locking in for 5 years provides extreme security but usually comes with the risk of being stuck on a higher rate if the market drops. Shorter terms allow first home buyers to reassess their income and property equity more frequently without being locked in long-term.

      Conclusion: Making Your Decision

      Deciding whether to fix or float your mortgage in NZ in 2026 ultimately comes down to a balancing act between budget certainty and repayment flexibility.

      If you value knowing exactly what your outgoings will be every payday, fixing is the undeniable winner. If you are an aggressive saver hunting down every opportunity to crush your debt, floating offers the freedom to make massive dents in your principal without being punished by break fees. For the vast majority of Kiwis, a split mortgage strategy remains the gold standard, offering a safety net for the bulk of your debt while giving you a floating runway to channel extra cash.

      Don’t just guess what your repayments will look like. Before you sign your next loan document, crunch the numbers yourself and see the real-dollar impact.

    • NZ First Home Buyer Guide 2026: From KiwiSaver to Settlement

      Date: 12/05/2026

      Author: Luca Tariciotti

      Buying your first home in New Zealand is a multi-step journey that requires unlocking your KiwiSaver deposit, securing mortgage pre-approval, conducting thorough property due diligence, and carefully navigating the final settlement process. This step-by-step roadmap matters specifically for New Zealanders right now because, with recent shifts in Reserve Bank lending limits and the complete cancellation of older government grants, having an up-to-date 2026 game plan is the only way to successfully get onto the property ladder without making incredibly expensive mistakes.

      Welcome to the club! If you are reading this, you are likely getting serious about buying your first house. It is a massive milestone and, let’s be completely real here, it can feel more than a little overwhelming when you are just starting out. You are suddenly bombarded with a ton of jargon from real estate agents, mortgage brokers, and lawyers, and it feels like everyone else got an instruction manual that you somehow missed out on.

      But do not stress—I am here to walk you through it like a knowledgeable friend, not a dry financial adviser. We are going to break the entire home-buying journey down into a practical, bite-sized process so you know exactly what to expect from day one to the day you finally get the keys.

      Step 1: Cracking Open Your KiwiSaver for the Deposit

      Let’s tackle the biggest and scariest roadblock for most of us: the deposit. Thanks to current Reserve Bank LVR (Loan-to-Value Ratio) restrictions, banks in New Zealand generally want to see a solid 20% deposit before they will even look at your mortgage application. If you are eyeing up a modest starter home in a place like Hamilton or Christchurch for $700,000, a 20% deposit is a whopping $140,000.

      That takes years of hard saving. But hold up—you usually do not need to scrape all of that together from your take-home pay alone. If you have been chipping away into your KiwiSaver, you can actually raid your retirement stash to help get yourself into a home today.

      Here are the strict KiwiSaver First Home withdrawal rules for 2026:

      • You must have been contributing to your KiwiSaver for at least three full years.
      • You must leave a minimum balance of exactly $1,000 in the account. You cannot drain it to zero!
      • You must intend to actually live in the house. You cannot use this money to buy a rental property.
      • It needs to be your first home. (Though if you have owned property before but are now back to square one financially, look up Kāinga Ora’s rules for a “second chance” buyer—you might still qualify).

      Let’s look at a real-world example with actual NZ dollars. Say you and your partner want to buy a place together. You have $45,000 sitting in your KiwiSaver, and your partner has $38,000. Once you both leave your mandatory $1,000 in there, you have a combined $81,000 ready to slap down for your deposit. That is a massive head start before you even count the cash sitting in your everyday savings accounts!

      Tip for later: Wondering how your mortgage payments will fit into your budget after tax? Check out our Hourly to Take-Home Pay Calculator to see exactly what cash you have left over each week.

      Step 2: The Honest Truth About Government Grants in 2026

      Now, let’s clear the air about government freebies. You have probably heard your mates, your parents, or older internet guides talking about how the government gives you free money to buy a house, usually referred to as the First Home Grant or HomeStart grant.

      The brutal truth? The government completely cancelled that grant back in May 2024.

      Yeah, it really sucks missing out on a free top-up. But there is no use crying over spilled milk, and we need to deal with the reality of the 2026 housing market. Instead of dwelling on what’s gone, we need to focus on what can help you right now.

      The fantastic news is that the First Home Loan scheme is still alive and thriving. This beauty of a scheme lets you buy a place with just a 5% deposit instead of the scary 20%.

      So, for that same $700,000 house we talked about earlier, a 5% deposit is just $35,000. If you have steady work but you have struggled to save heaps of cash because rent is so ridiculously high, this scheme is your absolute best mate. You will need to meet some income caps—usually around $95,000 for a single buyer or $150,000 for a couple or a solo parent—and you will need to pay a 1.2% Lender’s Mortgage Insurance (LMI) fee, but it is totally worth looking into to get your foot in the door.

      Step 3: Beating the New Rules to Get Mortgage Pre-Approval

      Okay, so you know what cash you have for a deposit. Now you need to know what the bank will actually let you borrow. We call this getting your “pre-approval.”

      Whatever you do, please do not go to open homes and fall in love with a place without having this sorted first. It’s like window shopping with no wallet—it’s just pure torture. Pre-approval gives you a rock-solid budget and proves to the real estate agents that you are a serious buyer.

      To give you pre-approval, the bank is going to snoop through your life. They will look at your income, your daily expenses, your student loans, and your credit card limits.

      Crucially in 2026, you also need to beat the Debt-to-Income (DTI) rules. Introduced recently by the Reserve Bank, this rule generally states that you cannot borrow more than six times your household’s annual income. For example, if you and your partner earn a combined $120,000 a year, the maximum total debt the bank will usually let you take on is $720,000. They want to make sure you can easily handle the mortgage payments if interest rates jump up.

      Curious about what your future repayments might look like before you go talk to a bank?

      (Note: Once you know your budget, you can also use our Weekly Mortgage Calculator to play around with different interest rates and see how paying fortnightly instead of monthly can save you thousands!).

      My biggest tip here is to use a mortgage broker. They are absolute legends. They do all the boring, confusing paperwork, haggle with the banks to get you the best interest rates and tell you exactly which banks are currently loving first home buyers. The best part? They are generally free for you to use because the bank pays their fee.

      Step 4: Budgeting for the “Hidden Costs” of Buying

      A lot of first home buyers get so hyper-focused on the deposit that they forget about the extra costs of actually buying the house. Do not let these catch you out. You need to budget a few thousand dollars in cold, hard cash for the following:

      ExpenseEstimated CostWhy You Need It
      Lawyer Fees$1,500 – $2,500A property lawyer/conveyancer handles the legal title transfer and the massive sums of money.
      Registered Valuation$800 – $1,000The bank may force an independent valuation if you have less than a 20% deposit to confirm the house’s worth.
      LIM Report$300 – $450Council report showing flood risks, unconsented works, and property history.
      Builder’s Report$600 – $900Professional inspection for dodgy wiring, hidden leaks, and structural issues.
      Rates & InsuranceVariesHouse insurance is mandatory for a mortgage; you also reimburse the seller for prepaid council rates.
      Moving CostsVariesHiring a truck, packing supplies, and pizzas for your helpful mates.

      Step 5: Doing Your Due Diligence (Don’t Buy a Lemon)

      Pre-approval sorted? Extra cash saved for the lawyers? Sweet as! Now you can actually go out and start house hunting for real. But before you sign your life away on a property, you have to do your homework. In fancy property terms, this is called “due diligence.”

      You will want to set aside cash to pay for two main checks on any house you are serious about:

      • The Builder’s Report: You pay a professional building inspector to check the house inside and out. They will climb into the roof and under the floor to spot dodgy wiring, hidden leaks, and rotting timber that you totally missed because you were too busy admiring the nice kitchen benchtop. It costs about $600 to $900, but it can literally save you from buying a $50,000 leaky-home nightmare.
      • The LIM Report: This stands for Land Information Memorandum, and it comes straight from your local council. It tells you everything the council knows about the property. Will the section flood every winter? Did the guy who owned it before you build that massive deck without getting council consent? The LIM will tell you. This usually costs around $300 to $450 depending on where you live.

      Step 6: Making a Conditional Offer

      You found “the one!” Awesome. Now you get your lawyer to help you write up an offer, which is formally called a Sale and Purchase Agreement. Since it’s your first time buying, you definitely want to make a conditional offer.

      Making a conditional offer basically means telling the seller, “I want to buy your house, but only if…”

      • …my bank gives me the final thumbs up to lend money for this exact house (Subject to finance).
      • …the building inspector doesn’t find any nasty surprises (Subject to a builder’s report).
      • …my lawyer says the LIM report and legal title are all good to go (Subject to lawyer’s approval).

      Why does this matter? If the builder finds out the roof is totally shot, your conditional offer is your safety net. You can go back to the seller and say, “Hey, fix the roof, drop the price by $15,000, or I’m walking away and keeping my deposit.”

      Once all those conditions are ticked off and you are completely happy, your lawyer will tell the seller the contract is “unconditional.” That’s when things get very real. You are legally locked in, and you will usually need to transfer a cash deposit (often 5% or 10% of the purchase price) right then into the real estate agent’s secure trust account.

      Step 7: Settlement Day (Handover Time!)

      This is the finish line! Settlement day is the date you and the seller agreed on in the contract, and it is the day the property officially becomes yours. It is also the day the massive amounts of money finally move around.

      Do not worry, you aren’t carrying briefcases of cash around town. It all happens smoothly behind the scenes:

      1. Your KiwiSaver provider drops your withdrawn funds into your lawyer’s trust account.
      2. The bank sends the rest of the mortgage loan money to your lawyer.
      3. Your lawyer bundles all this money up and ships it over to the seller’s lawyer.
      4. Once the seller’s lawyer gets the cash, they ring the real estate agent and say, “Release the keys!”

      Just a quick heads up: the banking system can be a bit slow on settlement day, so do not expect to get the keys right at 9:00 AM. Go grab a pie, chill out, and usually by early to mid-afternoon, your phone will ring, and you will be walking through the front door of your very own place!

      Frequently Asked Questions

      How long does it actually take to get my KiwiSaver money out? It usually takes about 10 to 15 working days for your KiwiSaver provider to process the withdrawal. Because of this, you need to get the paperwork sorted early. You will even need to sign a statutory declaration in front of a Justice of the Peace! Your lawyer will help you coordinate this so the cash is ready well before settlement day.

      Can I use my KiwiSaver to pay the upfront deposit when I make an offer? Usually, nope. Your KiwiSaver funds go straight to your lawyer for settlement day. When you go unconditional, the real estate agent usually wants a cash deposit right then. If all your savings are tied up in KiwiSaver, do not panic—just tell your lawyer. They can add a special clause to your offer saying the deposit will be paid later on settlement day instead.

      Is the HomeStart/First Home Grant ever coming back? As of right now in 2026, no. It was scrapped in May 2024 and has not returned. Focus your energy on the First Home Loan scheme instead if you only have a 5% deposit.

      Do I really need to use a mortgage broker? You do not have to, but honestly, it is the smartest move you can make as a first home buyer. They translate all the confusing bank jargon, hunt down the best interest rates, and guide you through the whole process for free.

    • Weekly vs Fortnightly vs Monthly Mortgage Payments — Which Saves More in NZ?

      When deciding between a fortnightly vs monthly mortgage NZ, paying more frequently saves you money in the long run because it helps you easily make an extra month’s worth of repayments each year. With high interest rates taking a massive chunk out of Kiwi incomes, shaving years off your home loan through smart payment timing is crucial for everyday New Zealanders trying to get ahead.

      If you have recently bought a house or are looking to restructure your current home loan, you must decide how often to make your repayments. Most banks default to a monthly schedule, but as a borrower, you usually have the power to switch to weekly mortgage payments in NZ.

      Does it actually make a difference? Yes, a massive one. However, the savings don’t just come from the frequency itself; they come from a mathematical trick known as “accelerated” payments and how New Zealand banks calculate interest.

      Let’s break down the real financial difference between a fortnightly vs monthly mortgage in NZ, and see how a simple schedule change can save you tens of thousands of dollars.

      How New Zealand Banks Calculate Mortgage Interest

      To understand why paying more frequently saves you money, you first need to understand how banks charge interest. In New Zealand, banks calculate the interest on your home loan daily, but they usually charge it to your account monthly.

      Every single day, the bank looks at your outstanding loan balance, applies the daily interest rate (your annual rate divided by 365), and adds that to a running tally. Because the interest is calculated daily, the faster you reduce your principal loan balance—even by a little bit—the less interest you are charged the very next day.

      If you wait until the end of the month to make one large lump-sum payment, your loan balance stays high for 30 days. If you make a payment every week, your balance drops four times a month. You can read more about how daily interest works through financial literacy resources like Sorted.org.nz.

      The “Accelerated” Repayment Trick Explained

      The real secret to saving years on your mortgage isn’t just paying more often; it is how you calculate those smaller payments.

      If you ask the bank for a standard fortnightly repayment schedule, they will usually divide your total annual repayment amount by 26 (the number of fortnights in a year). Your total yearly payment stays exactly the same, and you save a tiny bit on daily interest.

      The real “trick” is to use accelerated payments. This is where you take your normal monthly repayment and simply cut it in half, paying that amount every fortnight.

      Because there are 12 months in a year, but 26 fortnights, paying half your monthly amount every two weeks results in you making 26 half-payments. That equals 13 full monthly payments across the year. Without even noticing the pinch in your budget, you have made a whole extra month’s repayment directly against the principal of your loan!

      Real NZ Dollar Example: A $600,000 Mortgage

      Let’s look at a realistic New Zealand scenario to see how this plays out over a standard 30-year term. Imagine you have a $600,000 mortgage at an interest rate of 6.50% p.a. (a typical rate depending on the current Official Cash Rate set by the RBNZ).

      Scenario A: Standard Monthly Repayments

      • Payment: $3,792 per month
      • Total payments per year: $45,504
      • Time to pay off loan: 30 years
      • Total interest paid: $765,263

      Scenario B: Accelerated Fortnightly Repayments Instead of paying monthly, you take that $3,792, chop it in half, and pay $1,896 every fortnight.

      • Payment: $1,896 per fortnight
      • Total payments per year: $49,296 (You’ve paid an extra $3,792 across the year)
      • Time to pay off loan: 24 years and 3 months
      • Total interest paid: $588,140

      By simply taking your monthly payment, halving it, and paying that amount every two weeks, you save $177,123 in interest and pay off your mortgage almost 6 years early. This is the ultimate power of the fortnightly vs monthly mortgage NZ debate.

      Want to see exactly how much you could save with different payment frequencies on your own home loan? Try our Weekly Mortgage Calculator to run your own numbers.

      Are Weekly Mortgage Payments in NZ Even Better?

      If fortnightly is good, is weekly better?

      If you decide to make weekly mortgage payments in NZ, you divide your monthly payment by four. In our $600,000 example, your monthly payment of $3,792 becomes a weekly payment of $948.

      Because there are 52 weeks in a year, paying $948 a week means you will pay $49,296 across the year. This is exactly the same annual total as the accelerated fortnightly method. However, because you chip away at your principal balance every seven days instead of every fourteen days, you get a slightly better result from the bank’s daily interest calculation.

      Using the accelerated weekly method on that same $600,000 loan:

      • Time to pay off loan: 24 years and 2 months (One month faster than fortnightly).
      • Total interest paid: $586,300 (Roughly $1,800 cheaper than fortnightly).

      While weekly payments are technically the most mathematically efficient, the difference is relatively small compared to the massive leap from monthly to fortnightly.

      Which Option Should You Choose?

      The best payment frequency for your mortgage usually depends on your pay cycle. Cash flow is king when managing a household budget, and aligning your mortgage outgoings with your salary is the best way to avoid financial stress.

      • Stick to Monthly if: You are paid monthly and struggle to manage your cash flow throughout the month. It ensures your biggest expense leaves your account the moment your salary lands.
      • Choose Fortnightly if: You receive your salary every two weeks. This is the sweet spot for the majority of Kiwis. Setting your mortgage to automatically deduct half the monthly amount the day after your pay clears is a painless way to shave years off your loan.
      • Choose Weekly if: You are a contractor, a tradie, or an employee who gets paid every week. It provides the absolute maximum interest savings and keeps your weekly budgeting incredibly consistent.

      Ultimately, whether you choose weekly or fortnightly, moving away from the default monthly schedule and making those accelerated extra payments is one of the smartest financial moves you can make to grow your net worth.

      Frequently Asked Questions

      Does paying weekly reduce interest faster than paying fortnightly? Yes, but only slightly. Because New Zealand banks calculate interest daily, paying weekly reduces your principal balance more frequently than paying fortnightly. However, the total extra savings are usually only a few thousand dollars over a 30-year term, whereas switching from monthly to an accelerated fortnightly payment can save you hundreds of thousands.

      Can I switch from monthly to weekly payments at any time in NZ? Most New Zealand banks allow you to change your payment frequency at any time without penalty, even if you are on a fixed interest rate. However, you should check your specific loan contract or call your bank, as some lenders might limit how much extra you can pay per year before triggering early repayment fees (often called break fees).

      Do all NZ banks allow “accelerated” weekly or fortnightly payments? Yes, any extra money you pay above your minimum required payment is effectively an “accelerated” payment. When you ask the bank to change your frequency, explicitly tell them you want to pay exactly half of your monthly payment every fortnight, rather than asking them to recalculate your minimum fortnightly requirement over the full 30-year term.

      What if I am on a fixed interest rate and want to pay more? If you are locked into a fixed interest rate, most NZ banks allow you to increase your regular payments by a certain amount (often up to 5% of the loan balance or a set dollar amount like $10,000 per year) without paying a break fee. Check your bank’s specific rules regarding extra payments on fixed terms.

    • How Much Can I Borrow? A Simple 2026 Guide to Secure Your NZ Home

      How Much Can I Borrow? A Simple 2026 Guide to Secure Your NZ Home

      If you are wondering ‘how much can I borrow?’, you can typically get between 4 to 6 times your gross annual household income, depending on your deposit size, living expenses, and current bank rules. This matters for New Zealanders specifically because our local housing market, strict Loan-to-Value Ratio (LVR) limits, and the latest Debt-to-Income (DTI) regulations mean that what you earn on paper might not match what a bank will actually lend you in today’s economic climate.

      Kia ora! If you are aiming to buy a house this year, figuring out the math is the very first step. You need to know exactly what the bank is willing to lend you before you start falling in love with properties at Sunday open homes.

      Figuring out your borrowing power isn’t as simple as checking your take-home pay and guessing what you can afford. The banks have a specific set of tests they run every single applicant through. They want to make absolutely sure that if life gets a bit messy, or if interest rates do a sudden jump, you won’t be put under unbearable financial stress.

      So, grab a flat white, and let’s break down exactly how the banks calculate your borrowing power in 2026, using some real Kiwi dollar examples to make it super clear.

      The Starting Point: Income Multiples

      Historically, when people asked how much they could borrow, the quickest rule of thumb was to use an income multiple. As a rough guide in 2026, banks are generally willing to lend you somewhere between 4 and 6 times your gross, before-tax household income.

      Let’s look at a quick real-world example. Meet Sarah and Tama. Sarah earns $80,000 a year, and Tama earns $70,000. Their combined gross household income is $150,000.

      Using the standard income multiples, the bank might be willing to lend them anywhere from $600,000 (which is 4 times their income) up to $900,000 (which is 6 times their income).

      But why is there such a massive $300,000 gap between those two numbers? That all comes down to their specific living expenses, any other debts they have, and the rules set by the Reserve Bank. The bank doesn’t just look at what you earn; they look at what you spend. If Sarah and Tama have kids in daycare, a hefty car loan, and a habit of eating out constantly, they are going to be sitting much closer to that 4x multiplier. If they are frugal savers with zero consumer debt, they might push closer to the 6x mark.

      LVR Restrictions: Have You Got the Deposit?

      Before the bank even looks deeply at your income limits, they want to know how much money you have saved up. This is where Loan-to-Value Ratio (LVR) restrictions come in.

      In simple terms, your LVR is the size of your loan compared to the value of the property you want to buy. The Reserve Bank of New Zealand tightly controls this to keep the country’s banking system safe and stable.

      For most standard owner-occupiers in 2026, the bank requires a 20% deposit. This means your LVR is 80%.

      Let’s put some NZ dollar amounts to this scenario. If you want to buy a standard 3-bedroom house in Christchurch for $750,000, you will generally need a 20% deposit.

      • 20% of $750,000 = $150,000.
      • This leaves a mortgage of $600,000.

      If you only have a $50,000 deposit, the bank won’t lend you the remaining $700,000 for that house, no matter how high your salary is, because you don’t meet the LVR criteria. There are exceptions for first-home buyers using specific government schemes (like the First Home Loan), but for the vast majority of Kiwis, hitting that 20% deposit mark is the golden ticket.

      The Hard Ceiling: DTI Rules Explained

      This is one of the most important pieces of the puzzle for 2026. Debt-to-Income (DTI) rules are speed limits set by the Reserve Bank that cap exactly how much debt you can take on relative to your income.

      While LVR rules restrict how much you can borrow based on your deposit, DTI rules restrict how much you can borrow based on your paycheck.

      For owner-occupiers, the general DTI limit is heavily restricted around the 6x mark. This means your total combined debt cannot exceed 6 times your gross income.

      Notice the phrasing there: total debt, not just your mortgage.

      Let’s bring back Sarah and Tama with their $150,000 combined income. Under a strict DTI cap of 6, their absolute maximum total debt allowed would be $900,000 ($150,000 x 6).

      However, they aren’t debt-free. Tama still owes $20,000 on his student loan, and they have a $10,000 limit on their joint credit card.

      • Maximum allowed debt: $900,000
      • Minus Student Loan: -$20,000
      • Minus Credit Card Limit: -$10,000
      • Maximum Mortgage Available: $870,000.

      The DTI rules act as a hard legal ceiling. Even if Sarah and Tama had a massive 50% deposit from an inheritance, the bank cannot give them a mortgage that pushes their total debt past that DTI cap.

      The Hidden Hurdle: Stress Test Rates

      So, you have your 20% deposit (passing the LVR test), and your total debt is well under 6 times your income (passing the DTI test). You’re good to go, right?

      Not quite. The final major hurdle of mortgage lending is the bank’s internal “stress test”.

      When you look at a bank’s website today, you might see a 1-year fixed mortgage rate advertised at around 6.5%. You might calculate your weekly payments on that 6.5% rate and think it fits perfectly into your budget.

      But the bank doesn’t just care if you can afford the mortgage today. They care if you can still afford the mortgage if the economy shifts and interest rates skyrocket.

      To protect themselves (and you), banks use a “stress test rate” to calculate your affordability. This rate is usually a good 2% to 3% higher than the actual interest rate you will pay. In 2026, it is common for banks to stress test your application at an interest rate around 8.5% to 9%.

      Let’s look at the financial reality of this: If you borrow $600,000 over 30 years:

      • At the advertised rate of 6.5%, your fortnightly payment would be roughly $1,740.
      • At the bank’s stress test rate of 8.5%, they calculate your fortnightly payment at around $2,120.

      When the bank looks at your income and expenses, they run the math using that higher $2,120 figure. If your budget is completely maxed out at the $1,740 payment and you’d have no money left for groceries if the payment hit $2,120, the bank will decline your application. They need to see a comfortable buffer.

      Putting It All Together: Uncommitted Monthly Income

      When a lending assessor sits down with your application, they are piecing together your Uncommitted Monthly Income (UMI). This is the magic number. It’s what is left over after they take your after-tax income and subtract all your fixed expenses, your living costs, and that stress-tested mortgage payment we just talked about.

      If your UMI is in the negative, the bank cannot lend to you. To improve your borrowing power, your best move is to tidy up your spending, pay down short-term consumer debt like credit cards and car loans, and save as hard as you can for that deposit.

      Frequently Asked Questions

      1. Do credit cards affect how much I can borrow for a mortgage? Yes, absolutely. Banks look at your total credit card limit, not your current balance. A $10,000 limit is treated as $10,000 of ongoing debt, which heavily impacts your Debt-to-Income (DTI) calculations and reduces the amount of mortgage money the bank will offer you. If you aren’t using the card, cancel it or lower the limit before you apply.

      2. Does my KiwiSaver count towards my house deposit? Yes! If you have been contributing to KiwiSaver for at least three years, you can withdraw almost all of your balance (leaving just $1,000 in the account) to use as a deposit for your first home. This helps you clear the LVR hurdles much faster.

      3. Can I get a mortgage in NZ with less than a 20% deposit? It is possible, but it is much harder. Banks are heavily restricted by LVR rules on how much “low deposit” lending they can do. You may need to look at options like finding a guarantor, purchasing a new build property (which often requires a smaller deposit), or using the government-backed First Home Loan scheme, which allows deposits as low as 5%.

      4. Does the bank take my student loan into account? Yes. Your student loan is a debt that requires a mandatory 12% deduction from your pay above a certain threshold. The bank factors this compulsory payment into your living expenses, which directly lowers your Uncommitted Monthly Income (UMI) and reduces your overall borrowing power under the DTI rules.
