Everything NZ first home buyers need to know: KiwiSaver first home withdrawal, the First Home Loan scheme, LVR and DTI rules, deposit strategies, and how to choose the right mortgage structure.
Getting your first home loan in New Zealand is one of the biggest financial decisions you’ll ever make — and the rules, schemes and lending conditions that shape it change regularly. Whether you’re saving your first dollar or standing at the pre-approval stage, this guide gives you a clear, practical roadmap: KiwiSaver withdrawals, the Kāinga Ora First Home Loan, LVR and DTI rules, deposit strategies and mortgage structure. It’s general information, not financial advice, and scheme settings change — always confirm current rules directly with the source.
Before a bank lends you hundreds of thousands, they want evidence you’re a low-risk borrower — which means more than a stable salary. Most lenders want at least 5% in genuine savings (funds you’ve accumulated yourself, not a sudden gift), and KiwiSaver balances generally qualify, which is one reason the scheme is so central to deposits. The key is a consistent savings habit — regular transfers to a dedicated account tell a far more compelling story than a large deposit three weeks before you apply. In the months before applying, clean up your credit and statements: pull a free credit report (from Centrix or Equifax) three-to-six months early to fix any issues, and review your bank statements through a lender’s eyes — frequent BNPL, gambling or takeaway charges all raise flags, so reduce unnecessary subscriptions and avoid new debt, including car finance. And stress-test your own budget: banks add a 2–3 percentage-point serviceability buffer, and you can run the same exercise with our home loan calculator.
On debt-to-income (DTI): most owner-occupiers are limited to total debt of no more than six times gross income, so a household earning $120,000 could borrow up to about $720,000 — though lenders may set tighter internal limits. So pay down high-interest debt first (credit cards and personal loans reduce your capacity dollar for dollar), avoid new commitments in the six months before applying, and get advice before rolling any debt into a mortgage.
For most New Zealanders, the KiwiSaver first-home withdrawal is the single biggest boost to their deposit.
A government-backed route to buy with a 5% deposit. Kāinga Ora underwrites the loan; a participating bank issues it.
| Standard bank loan | First Home Loan | |
|---|---|---|
| Minimum deposit | Typically 10–20% | 5% |
| Income limits | None (serviceability-based) | $95k single / $150k with dependants or two+ buyers |
| Low-deposit cost | Low-equity margin (ongoing rate premium) | ~1.2% insurance premium (one-off, can be added to the loan) — no Kāinga Ora low-equity fee |
| LVR / DTI speed limits | Apply | Exempt (bank still runs its own credit checks) |
| House price caps | None | National caps removed in 2022; regional/situational limits may still apply |
Scheme settings — income caps, the premium and any price caps — are reviewed periodically and vary by situation. Always confirm the current rules at kaingaora.govt.nz before making an offer. A “second chance” provision may help previous owners now in a similar position to a first-home buyer.
Our KiwiSaver guide covers contributions and fund choice, and the KiwiSaver withdrawal guide has the full step-by-step for the first-home withdrawal.
Worth being clear about: the First Home Grant — the government subsidy of up to $10,000 — closed to new applications on 22 May 2024. If you applied and were approved before then, those funds remain valid, but new applicants can no longer access it. The government’s focus has shifted to the First Home Loan (below) and housing supply, and some iwi and community housing providers offer their own assistance — worth checking with your local council, particularly in regional centres. The closure doesn’t diminish KiwiSaver’s importance, though: your withdrawal balance, built from your pay, your employer’s contributions and the government contribution, remains one of the most powerful deposit tools available.
The RBNZ’s LVR restrictions limit how much low-deposit lending banks can do — for owner-occupiers, from 1 December 2025 banks can lend up to 25% of their new lending to borrowers with less than a 20% deposit (an LVR above 80%). In practice most first home buyers still aim for a 20% deposit to access the best rates and avoid a low-equity margin (a rate premium of roughly 0.25–1.5% on loans above 80% LVR) — but banks do approve low-deposit applications, especially for strong incomes and clean credit. And the First Home Loan is designed specifically for buyers who can’t reach 20%.
New Zealand borrowers overwhelmingly favour fixed rates — fixing gives certainty for a term (typically six months to five years), while floating rates are usually higher but let you make extra repayments or repay entirely without a break fee. Most advisers recommend a split structure for first home buyers: fix the majority for certainty, and leave a smaller portion floating (or as revolving credit) so you can make lump-sum repayments when you have spare cash. An offset facility links a savings account to your loan so you pay interest only on the difference (owe $500,000, hold $30,000 offset, pay interest on $470,000), and revolving credit works like a large secured overdraft — both suit disciplined savers, and are less effective if you tend to spend what’s available. On term: most loans run 25–30 years, and a longer term lowers the minimum repayment but sharply increases total interest — so where possible, pay above the minimum from day one (even an extra $50 a week on a $500,000 loan can shave years off and save tens of thousands). For the wider mortgage picture, see our home loans guide, and you can model repayments with the ANZ home loan calculator.
New Zealand has a well-developed mortgage adviser (broker) industry, and for first home buyers it often makes sense. A registered adviser can compare products across multiple lenders — including non-banks like Pepper Money or Liberty Financial — and structure your application to maximise approval, and they’re paid by the lender on settlement, so there’s typically no direct cost to you (though not all have access to every lender, so ask which they work with). Going direct to your own bank can work well with a strong existing relationship and a clean profile — the risk is they’ll only show you their own products.
Compound interest earns returns on your returns. The gap looks modest early on, then it explodes.
| Scenario | After 10 years | After 30 years |
|---|---|---|
| Simple interest | $15,000 | $25,000 |
| Compound (annual) | $16,289 | $43,219 |
| Compound (monthly) | $16,470 | $44,677 |
At 30 years, compounding produces almost twice the wealth of simple interest from the same start — which is why the advice is always to start early and leave it untouched.
A few practical tips to strengthen your application: show consistent savings over at least three months; close unused credit cards or reduce their limits (lenders count the full limit as potential debt); avoid switching jobs in the three months before applying; be scrupulously honest (misrepresenting income or liabilities is fraud); and get independent legal advice on any family loan or guarantee before signing. It’s also worth considering where you buy — median prices vary enormously by region, and a regional centre rather than a main centre can mean a smaller deposit and a more manageable mortgage, potentially getting you into the market sooner.
Buying your first home is absolutely achievable with the right preparation. Start by checking your KiwiSaver balance and withdrawal eligibility, run the numbers on what you can realistically borrow, and get a clear picture of your credit profile before approaching any lender. If it feels overwhelming, a registered mortgage adviser can map out a personalised plan at no cost to you. The goal is to walk into your first open home knowing exactly what you can afford — and to walk out of settlement day holding the keys to a home you can genuinely sustain.
Disclaimer: This article is general information for first home buyers in New Zealand, not financial advice. Scheme settings — KiwiSaver rules, the First Home Loan’s income caps, premium and any price caps, and the RBNZ’s LVR and DTI limits — change and vary by situation, and some details here are indicative for 2026. Always confirm current rules directly with Kāinga Ora, your KiwiSaver provider and your lender before you rely on them, and consider advice from a registered mortgage adviser. See Kāinga Ora (kaingaora.govt.nz).
Your starting balance — the lump sum you begin with (though regular contributions matter more over time).
Your annual return — a savings rate, or a projected KiwiSaver/fund return. Model your after-tax rate.
How often interest is added — daily, monthly, quarterly or annually. More often is slightly better.
Years invested — the most powerful variable of all. Every extra year compounds on everything before it.
Most NZ savings accounts compound monthly; some term deposits only at maturity; KiwiSaver and managed funds effectively compound continuously as returns are reinvested as units. When you model your numbers, watch three figures: total contributions, total returns earned, and the final balance.
Most lenders want 20% for the best rates, but there are lower-deposit routes: the Kāinga Ora First Home Loan lets eligible buyers in with just 5%, and banks can do a limited share of low-deposit lending (usually with a low-equity margin). Your KiwiSaver first-home withdrawal can make up much of the deposit.
Yes — if you’ve been a member for at least three years and have never owned property (or have Kāinga Ora second-chance approval), you can withdraw almost your whole balance (including employer and government contributions), leaving a minimum of $1,000. The funds go directly to your solicitor on settlement, so apply four to six weeks ahead.
A government-backed scheme letting eligible first home buyers purchase with a 5% deposit through a participating bank, with Kāinga Ora underwriting the loan. Income caps apply ($95,000 single / $150,000 for two or more buyers or a single buyer with dependants), and there’s a one-off insurance premium (around 1.2%) that can be added to the loan. Confirm the current settings with Kāinga Ora.
No — the First Home Grant closed to new applications on 22 May 2024 and no cash-grant replacement has been introduced. First home buyers should focus on the KiwiSaver first-home withdrawal and the Kāinga Ora First Home Loan instead.
From 1 December 2025, banks can lend up to 25% of their owner-occupier lending to borrowers with under a 20% deposit, and DTI caps limit most owner-occupiers to about six times gross income. Notably, Kāinga Ora First Home Loans are exempt from both speed limits, though the bank still runs its own credit and servicing checks.
For first home buyers, often yes — a registered adviser compares products across multiple lenders, helps structure your application, and is usually paid by the lender rather than you. Just ask which lenders they work with, since not all have access to every bank. Going direct can work well if you have a strong existing bank relationship.
