How to Buy Your First Home in New Zealand

Buying a first home in New Zealand typically requires a deposit of 20% of the purchase price, pre-approved finance from a lender, a solicitor to handle conveyancing, and insurance in place before settlement. With the Kāinga Ora First Home Loan, eligible buyers can enter with as little as 5%. KiwiSaver Scheme members with three or more years of membership can withdraw most of their balance toward the deposit.

Those are the mechanics. The more useful starting point is whether you are genuinely ready. The buyers who move through this process with the least stress tend to share a few traits: they understand their borrowing power before they fall in love with a property, they budget for the costs beyond the mortgage, and they keep enough buffer to absorb the surprises the first 12 months of ownership reliably delivers. Our advisers have guided several hundred New Zealanders through their first home purchase, and this article distils what we see work. It is reviewed when the Reserve Bank, Kāinga Ora, or Inland Revenue change the settings affecting first home buyers.

Understanding borrowing power before you start looking at properties is, in our experience, the single thing most reducing stress for first home buyers. Two households on the same salary can receive mortgage offers $150,000 apart because one has an unused $15,000 credit card limit and a small car loan, and the other closed those facilities six months earlier. The gap is not about income. It is about how lenders interpret existing liabilities. Getting this right early means you search within a realistic range and avoid the disappointment of finding a home you cannot actually finance.

Should You Buy Right Now?

Buying a home makes sense when you have stable income, a deposit or a clear path to one, and an intention to stay in one location for at least several years. It makes less sense when you are carrying high-interest debt, expecting a major life change, or buying purely because you feel you should. If the volume of detail ahead feels overwhelming, that is normal. Most first home buyers feel the same way at this point, and working through it methodically is what makes the difference.

Official guidance from Settled.govt.nz covers the procedural steps well. Where it necessarily stops short is on the judgement calls: whether your deposit buffer is genuinely sufficient or merely technically qualifying, whether a 5% deposit exposes you to negative equity risk if prices soften, or whether buying now at a stretch makes more sense than waiting 12 months to strengthen your position. Those are the questions worth working through with someone who sees these trade-offs regularly.

The transaction costs of buying and selling property in New Zealand are significant enough that short holding periods rarely work out financially. Solicitor fees, moving costs, and potential bright-line tax can eat into any short-term gain. For some people, renting and investing the difference produces a better outcome for several years, and the full decision criteria for holding off are worth considering honestly before you commit.

How Banks Assess Your Borrowing Power

Lenders examine your income, expenses, existing debts, and financial behaviour. Under the Responsible Lending Code administered by the Commerce Commission, New Zealand lenders must conduct detailed affordability assessments before providing credit.

Two regulatory frameworks from the Reserve Bank of New Zealand shape how much you can borrow and how much deposit you need.

Debt-to-income (DTI) restrictions, introduced by the RBNZ from 1 July 2024, limit most owner-occupier borrowing to six times gross annual income. A household earning $120,000 could theoretically borrow up to $720,000. In practice, banks also apply a stress-test interest rate to confirm you can service the loan if rates rise. Each lender sets its own stress-test rate, commonly 8% to 9.5% as of early 2026, though these shift with the rate cycle. This stress test often reduces effective borrowing power well below the headline DTI multiple. Understanding how the DTI calculation works before you apply helps you anticipate what a lender will actually offer.

Loan-to-value ratio (LVR) restrictions govern the minimum deposit. The standard requirement is 20% of the purchase price. As of 1 July 2024, the RBNZ permits banks to allocate up to 20% of new owner-occupier lending to borrowers with deposits below 20% (the "speed limit"). First home buyers are the primary beneficiaries of this flexibility. The RBNZ adjusts this figure periodically, so confirm the current setting via the RBNZ macro-prudential policy page before you apply.

In practical terms, these two frameworks together determine your search range. Work out the lower of your DTI ceiling and the amount a lender will approve under stress testing, subtract your deposit, and you have the price bracket worth looking in. Searching above it wastes time and builds emotional attachment to homes you cannot finance.

Banks also treat unspent overdraft limits and credit card limits as existing debt, even when the balance is zero. A $10,000 credit card you never use can reduce your borrowing power by $30,000 to $50,000, depending on the lender. If you carry unused facilities, close them before applying.

What to Fix Before You Apply

• Pay down debts: Clear credit cards and buy now, pay later balances first.
• Close unused credit: Unused overdrafts and credit cards reduce borrowing power even at zero balance.
• Reduce discretionary spending: Cancel subscriptions you do not use and rein in non-essential spending.
• Boost your income: Career advancement or additional income can meaningfully shift what a lender will offer you.
• Maintain a clean credit history: Late payments, defaults, and frequent applications all weigh against you.

In our experience, the single change with the largest impact is closing unused credit facilities. It costs nothing and takes a few days, yet we regularly see it add $30,000 or more to a pre-approval figure.

Your Deposit: How Much and Where From

The standard deposit is 20% of the purchase price. For a $700,000 property, that means $140,000. Your deposit can come from personal savings, investments, KiwiSaver Scheme withdrawals, and gifts from family.

KiwiSaver First Home Withdrawal

If you have been a KiwiSaver Scheme member for at least three years, you can withdraw most of your KiwiSaver investment balance to put toward a first home deposit. You must leave a minimum of $1,000 in the account, and the property must be one you intend to live in. The withdrawal cannot be used for an investment property.

The withdrawal includes your own contributions, employer contributions, government contributions (member tax credits), and accumulated investment returns.

Timing is critical. Apply to your KiwiSaver Scheme provider at least four to six weeks before your settlement date. The process works like this: you complete a withdrawal application with your provider, the provider verifies your eligibility and processes the request (typically 10 to 20 business days, though delays are common around month-end and quarter-end), and the funds are then paid directly to your solicitor's trust account. If you leave this too late, you risk delaying settlement and potentially losing the property.

If you have owned property before but no longer do, you may qualify for a "second chance" withdrawal. Kāinga Ora can assess whether your current financial position is similar to a first home buyer's.

Note: The First Home Grant was discontinued in May 2024 and is no longer available. The First Home Partner Scheme is also closed. The KiwiSaver first home withdrawal and the First Home Loan are separate programmes and remain fully available.

The First Home Loan

The Kāinga Ora First Home Loan allows eligible buyers to purchase with a deposit of just 5%. Kāinga Ora underwrites the risk, enabling participating banks to accept a lower deposit than they would normally require.

A 5% deposit is the minimum entry point, not the recommended one. Buying at 95% loan-to-value means you start with minimal equity, and even a modest drop in property values can push you into negative equity. If you have the option of waiting six months to build a 10% deposit instead, the additional buffer often proves its worth. For buyers who cannot wait, the First Home Loan serves a genuine purpose, but go in with clear eyes about the trade-off.

A lender's mortgage insurance (LMI) premium applies, typically around 1% to 1.5% of the loan amount. It can usually be capitalised into the loan. LMI protects the lender, not you: if you default, the insurer pays the lender, not you.

To qualify (per Kāinga Ora eligibility criteria at time of writing), you must be a New Zealand citizen or permanent resident, have a before-tax income of $95,000 or less (single buyer without dependants) or $150,000 or less (two or more buyers), and intend to live in the property.

Regional house price caps also apply. These vary by location and set the maximum purchase price for an eligible property. As a guide, caps have historically been set at approximately $875,000 in Auckland and Queenstown-Lakes, $750,000 in Wellington, and $600,000 to $650,000 in most other regions. Kāinga Ora updates these thresholds periodically, so confirm the current caps for your area on the Kāinga Ora website before relying on them.

Participating lenders include Westpac, Kiwibank, SBS Bank, Co-operative Bank, ASB, NZHL, and Unity. Interest rates, fees, and credit criteria vary between lenders, so comparing options (or working with a mortgage adviser who can do this for you) is worthwhile.

You can use a KiwiSaver first home withdrawal as your 5% deposit for a First Home Loan. This is one of the most common ways first home buyers enter the market.

A Worked Example: Deposit Composition

Consider a couple earning $130,000 combined gross income, purchasing a $700,000 first home.

• KiwiSaver Scheme withdrawal: Partner A withdraws $28,000 (leaving $1,000); Partner B withdraws $19,000 (leaving $1,000). Total from KiwiSaver investments: $47,000.
• Personal savings: $25,000.
• Total deposit: $72,000 (approximately 10.3% of the purchase price).

With a standard bank loan, this couple would need to qualify under the lender's low-deposit allocation. With a First Home Loan (their income of $130,000 is below the $150,000 threshold for two buyers, per Kāinga Ora criteria), they could purchase with just $35,000 (5% of $700,000) and keep the remaining savings as a buffer.

The trade-off: LMI on a $665,000 loan would cost approximately $6,650 to $9,975 (depending on the lender and exact LVR), added to the loan balance. Both paths work. The right one depends on how much buffer the couple wants to retain and whether the property falls within the regional price cap. The principle from earlier applies here too: the buyers who keep a meaningful buffer after settlement consistently report less financial pressure in the first year.

If a couple or group of friends is buying together, similar deposit arithmetic applies, but a co-ownership agreement drafted by a solicitor becomes essential.

Help from Family

Family assistance, sometimes called the "Bank of Mum and Dad," plays a growing role in first home purchases. Options include outright gifts, interest-free loans, and guarantees against a parent's property. If you go down this route, all parties should take independent legal advice. What happens if you separate from a partner? What if your parents need the money back? A properly drafted agreement avoids disputes and protects everyone involved.

KiwiSaver: Recent Changes Worth Knowing

Several recent changes to the KiwiSaver Scheme affect first home buyers building a deposit.

• Higher default contributions: From April 2026, default employee and employer contributions have both increased from 3% to 3.5%, with a further increase to 4% in April 2028. If you are several years from purchasing, your balance will build faster without any action on your part.
• Reduced government contribution: The member tax credit is now 25 cents per dollar you contribute, up to approximately $261 per year. Members earning $180,000 or more no longer receive the government contribution.
• Younger members: From April 2026, employed 16- and 17-year-olds qualify for employer contributions for the first time.

These changes interact with choosing the right KiwiSaver Scheme fund and provider, and the full detail on what has changed is worth reading if you are still several years from purchasing.

Getting Pre-Approved

A mortgage pre-approval is a formal indication from a lender confirming it is prepared, in principle, to lend you a specific amount. It sets your budget, strengthens your offer in the eyes of sellers and agents, and speeds up the process once you find a property.

Pre-approval is typically valid for several months and can usually be extended, provided your financial position has not changed materially. To obtain one, you will generally need pay slips or proof of income (three to six months), bank statements (three months), tax returns for the last two years if self-employed, a statement of assets including your KiwiSaver investment balance, and a statement of liabilities including credit cards, student loans, and buy now, pay later balances.

One important caveat: pre-approval is conditional, and a lender can withdraw it. It is a strong signal of intent, not guaranteed finance. The final loan offer comes only after the lender has assessed the specific property you are buying.

Build Your Team

Mortgage Adviser

A good mortgage adviser assesses different lenders and identifies where you are best placed to obtain a mortgage. They can often negotiate a more competitive interest rate and potentially a cashback offer on your behalf. In most cases, using a mortgage adviser costs you nothing; the lender pays their fee.

Solicitor

Your lawyer handles the legal side: reviewing the Sale and Purchase Agreement before you sign, conducting a title search, advising on easements, covenants, and consent notices, facilitating your KiwiSaver investment withdrawal, and managing settlement. For unit title properties, your solicitor also reviews the pre-settlement disclosure statement required under the Unit Titles Act 2010. Budget approximately $1,500 to $3,000 for conveyancing fees.

Property Professionals

Most banks require a registered valuation before confirming a mortgage ($600 to $1,000). A building inspection ($500 to $800) is not always mandatory, but on a transaction worth several hundred thousand dollars it is one of the cheapest forms of protection available. New Zealand has a mixed reputation for housing quality, and potential issues extend well beyond the leaky building era. Meth contamination, weathertightness problems, and non-consented work are all hazards a professional inspection can identify before you commit.

If you want to catch the common misreads before they cost you, our first home buyer advisers can pressure-test your borrowing power, deposit position, and assumptions. A first conversation is complimentary.

The True Costs of Buying and Owning

Upfront Costs

Beyond the deposit, upfront costs typically include a property valuation, building inspection, LIM report, solicitor's fees, and moving costs. Together, these can easily reach $5,000 to $10,000 or more.

Ongoing Costs

Council rates, house insurance (which the lender will require), contents insurance, and regular maintenance are all recurring expenses. Regional council websites publish rates assessments and basic property data.

For buyers purchasing an apartment or townhouse under unit title, body corporate levies are an additional ongoing cost. These range from modest ($2,000 to $3,000 per year for a small townhouse complex) to substantial ($8,000 or more per year for a larger apartment building with lifts, pools, or deferred maintenance). Always request the body corporate financial statements and the long-term maintenance plan before committing. These documents give you the clearest picture of what you will actually pay each year and whether a large special levy is on the horizon.

Stress-Test Your Budget

When you apply for a mortgage, the bank will test your cash flow against a higher interest rate. You should do the same. A household with a $600,000 mortgage at 5.5% pays roughly $3,700 per month. At 7.5%, the same mortgage costs approximately $4,400 per month.

Add council rates (around $250 per month), insurance (around $150 per month), and a maintenance reserve (around $200 per month), and total housing costs sit between $4,300 and $5,000 per month at the lower rate. If an extra $700 per month would create genuine hardship, consider purchasing at a lower price point.

A useful rule of thumb: if total housing costs (mortgage, rates, insurance, maintenance) exceed 35% of your after-tax household income at the stress-test rate, your buffer is uncomfortably thin. You can service it on paper, but a redundancy, a parental leave period, or a large unexpected repair can turn tight into unmanageable. This is one area where the official affordability tests do not fully capture the real-world risk.

The Bright-Line Test

The bright-line property rule was reduced to two years for all residential property from 1 July 2024. The change was enacted under the Taxation (Annual Rates for 2024–25, Emergency Response, and Remedial Matters) Act 2024. Any gain on a residential property sold within two years of purchase may be taxable.

An owner-occupied "main home" exemption exists, but conditions must be met. This matters for first home buyers because life can change: a job relocation, a relationship breakdown, or an unexpected move could trigger a sale within the bright-line period. Your solicitor can advise on how this applies to your situation, and further detail is available from Inland Revenue.

House Hunting and Making an Offer

With your finances and pre-approval sorted, the search begins. If you are buying with a partner, agree on priorities before you start looking. Spend time learning about different property types, familiarise yourself with real estate terminology, and understand the potential issues to watch for. Check listings online, attend open homes, and let agents know your criteria.

Do Your Homework

Once you have narrowed your search, find out as much as you can about the property and its neighbourhood before making an offer. Review the LIM report, check flood and natural hazard overlays on your local council's website, and talk to neighbours if you can. Drive past the property at different times of day and on different days of the week.

If you are considering an apartment or townhouse under unit title, review the body corporate minutes and long-term maintenance plan, and check for upcoming special levies or building remediation work.

How You Buy: Auction, Negotiation, and Other Methods

Properties in New Zealand sell by negotiation, auction, deadline sale, or tender. Auction requires particular preparation: all bids are unconditional, meaning you must have your finance confirmed, building inspection completed, and legal review of the title finished before bidding day. You cannot add conditions after the hammer falls. If auctions are common in your target area, have your due diligence complete before you walk into the room.

In practice, first home buyers are often better served targeting properties sold by negotiation or deadline sale, where conditions are possible. An unconditional bid at auction feels decisive, but for a buyer stretching to enter the market, the inability to walk away if a building report reveals problems is a real risk. If the market in your area is predominantly auction-driven, factor in the cost of multiple pre-purchase building inspections and valuations on properties you may not win.

A conditional offer (used in negotiation or deadline sale) means conditions must be satisfied before you commit: confirming finance, obtaining a satisfactory building report, or reviewing a LIM, for example. Conditions always have a timeframe. An unconditional offer means you are committed to buying the property as it stands.

Making and signing an offer can create a legally binding contract once accepted. Always have your solicitor review the Sale and Purchase Agreement before you sign.

Using Conditions to Your Advantage

Conditions are negotiating tools. If your building report reveals a roof nearing end of life, non-consented work, or deferred maintenance, you can return to the vendor and negotiate a price reduction or request the work be completed before settlement. Many first home buyers accept building report findings at face value and proceed without negotiation. A well-documented report gives you leverage.

Similarly, if your solicitor identifies title issues such as an unregistered easement or a consent notice requiring specific maintenance, these can form the basis of further negotiation or give you grounds to withdraw.

Settlement and Moving In

• Confirm loan structure: Your mortgage adviser will help you decide how to structure the loan. Once agreed, the bank prepares loan documents and sends them to your solicitor. The choice between fixed and floating rates depends on your outlook on interest rates and your appetite for certainty versus flexibility.
• Arrange house insurance: You will need house insurance in place before settlement. The lender will require proof of cover and will be listed as an interested party on the policy. Arrange contents insurance from day one as well.
• Review your broader cover: Taking on a mortgage changes your insurance needs. If your household relies on one or two incomes to service a large loan, income protection covers mortgage payments during a period when you cannot work. Life insurance ensures a surviving partner is not left with a debt they cannot service alone. The right level of cover depends on the specific loan amount, so reviewing this with an adviser once your borrowing is confirmed is a practical next step.
• Final inspection: Arrange a walk-through via the real estate agent. Confirm all inclusions listed in the Sale and Purchase Agreement are still in place and no damage has occurred since you signed.
• Transfer remaining funds: Ensure any remaining deposit or settlement funds are transferred to your solicitor's trust account as directed.

On settlement day, most of the work is handled behind the scenes by your solicitor and the bank. Once funds have settled and the title has transferred, you receive the keys.

Set up power, gas, internet, and water accounts at the new address. Update your address with NZTA, Inland Revenue, your bank, and your employer. Take meter readings on arrival to avoid disputes over the first bill. Keep your solicitor's settlement statement and all purchase documents in a safe place.

Common Mistakes to Avoid

These six mistakes share a common root: the combination of time pressure, optimism, and unfamiliarity with a process most people go through only once or twice in their lives. Knowing where others stumble helps you slow down at the right moments.

1. Borrowing to your maximum. The bank's maximum offer reflects what you can service under a stress-test rate. It is not a spending target. First home buyers who purchase at 75% to 80% of their approved amount and preserve a meaningful buffer report far less financial pressure in the first two years, particularly when an appliance fails or rates increase at the next review.
2. Waiving conditions under competitive pressure. Sellers and agents may prefer unconditional offers. An unconditional offer on a property with hidden defects means you own the defects. The cost of losing a property at auction is a weekend. The cost of buying one with non-consented work or a failing roof can rival the deposit you just put down.
3. Leaving the KiwiSaver withdrawal to the last minute. Providers process applications in 10 to 20 business days under normal conditions. Delays around month-end and quarter-end are common. Apply four to six weeks before settlement.
4. Budgeting only for the mortgage. Rates, insurance, maintenance, and body corporate levies (if applicable) typically add $500 to $800 per month on top of your mortgage repayment. First home buyers who ignore these costs frequently find themselves short within six months.
5. Skipping the building inspection. On a $700,000 purchase, a $500 to $800 inspection is 0.1% of the transaction value. Beyond identifying problems, a detailed report gives you documented evidence to negotiate a price reduction or request vendor-funded repairs before settlement.
6. Treating pre-approval as guaranteed finance. Pre-approval can be withdrawn if your circumstances change, if the property does not meet the lender's criteria, or if the valuation comes in below the purchase price. Do not make an unconditional offer based solely on a pre-approval letter.

Frequently Asked Questions

Can I buy a first home if I am self-employed?

Yes, but lenders typically require two years of filed tax returns and a consistent income history. Some lenders and most non-bank lenders apply different criteria, so a mortgage adviser who understands your income structure can make a material difference to the outcome.

Do both partners need to be KiwiSaver Scheme members to use a KiwiSaver first home withdrawal?

Each partner withdraws from their own KiwiSaver investment independently. One partner can use their withdrawal even if the other is not a member or has not met the three-year eligibility requirement.

Can I buy a new build with a smaller deposit?

The RBNZ has historically applied more favourable LVR treatment to new-build purchases, allowing deposits below 20% outside the standard speed limit allocation. These settings are adjusted periodically, and the current position may differ from past practice. Confirm with your lender or adviser before relying on it. The broader trade-offs between new builds and existing properties are also worth weighing up.

What happens if my settlement is delayed?

The standard ADLS/REINZ Sale and Purchase Agreement includes a penalty interest provision. If you cause the delay (for example, through a late KiwiSaver withdrawal), you may owe the vendor daily interest on the purchase price at the rate specified in the agreement, commonly around 10% per annum under the standard ADLS/REINZ terms.

After Settlement: Building on What You Have

Most first home buyers find the first 12 months of ownership costs more than they expected, primarily due to maintenance, furnishing, and minor repairs not visible during the buying process. A cash reserve of $5,000 to $10,000, kept liquid and separate from your everyday account, covers the majority of surprises without forcing you onto a credit card.

How your deposit, borrowing power, and KiwiSaver investment interact often surfaces connections and blind spots people overlook. If you would like help sense-checking your assumptions, a first conversation with one of our advisers is complimentary and carries no obligation.
