Complete First Home Buyer Guide for New Zealand 2026

Buying your first home in New Zealand in 2026 is exciting — but the process has a lot of moving parts: deposit, KiwiSaver, the First Home Loan scheme, lender choice, pre-approval and finally settlement. This plain-English guide walks you through each step in the order most first home buyers actually need it.

1. Work out how much deposit you really need

Most NZ banks want a 20% deposit for a standard home loan. However, banks have a small pool of low-deposit lending (under the Reserve Bank's LVR rules) which lets some buyers get in with as little as 10%. If you qualify for the First Home Loan (administered by Kāinga Ora), you may be able to buy with just a 5% deposit.

• Existing home — typically 20% deposit (10% low-equity in some cases)
• New build — often only 10% deposit, with no low-equity margin
• First Home Loan (Kāinga Ora) — 5% deposit, subject to income and price caps

Use our Deposit Savings Calculator to map out how long it will take to reach your target.

2. Use your KiwiSaver the smart way

If you've been in KiwiSaver for at least three years, you can withdraw most of your balance (you must leave $1,000 in the account) to put toward your first home. For many buyers, this is the single biggest part of their deposit.

You can also check eligibility for the First Home Grant (where still available) and any regional price caps. Our KiwiSaver First Home Calculator shows how your balance and contributions feed into your usable deposit.

3. Understand how banks assess your borrowing power

Lenders don't just look at your income — they stress-test it. In 2026 most banks are testing your repayments at around 8–9%, well above the actual rate you'll pay, to make sure you can cope if rates rise. They'll also look at:

• Your income (and how stable it is — PAYE, self-employed, contract)
• Existing debts: car loans, credit cards, Buy Now Pay Later, student loan
• Living expenses (banks now scrutinise these under the CCCFA)
• Number of dependants

Try our Borrowing Power Calculator for an indicative figure before you talk to a bank.

4. Get a pre-approval before you start house hunting

A pre-approval (also called a "conditional approval") tells you exactly how much a lender is willing to lend you, and on what conditions. Without one, you're shopping with no real budget — and you can't bid at auction with confidence.

A good financial adviser will compare offers from multiple lenders, structure the loan correctly, and present your application in the strongest light. This often makes the difference between "declined" and "approved".

5. Structure your mortgage properly

One of the most overlooked parts of buying a first home is loan structure. The right mix of fixed and floating portions, the length of each fixed term, and whether to include a revolving credit account can save (or cost) you tens of thousands over the life of the loan.

Use the Mortgage Repayment Calculator to test different rates and terms.

6. Budget for the costs beyond the deposit

• Legal fees — typically $1,500–$2,500
• Building inspection — around $500–$900
• LIM report — $300–$450 depending on council
• Valuation (if the bank requires one) — around $900
• Moving + insurance — house, contents and life/income protection

7. Talk to an adviser early — not at the last minute

The biggest difference between a smooth first home purchase and a stressful one is usually how early you start the conversation. Even if you're 12 months away, an adviser can map out exactly what you need to do — pay down a card, restructure a car loan, top up your KiwiSaver — so you're ready when the right property comes up.
