First Home Buyers in NZ: Financing Your Purchase and Understanding the Legal Process | NZ Legal

Buying your first home in New Zealand is one of the biggest financial decisions you will ever make. There is a lot to get your head around: how much you can borrow, what help is available, what documents you are signing, and what your rights are at each step.

This guide cuts through the jargon. It covers the financing options available to first home buyers with stretched budgets, the legal documents you will encounter, and what a good property lawyer does so you can walk into settlement day with confidence. For a full overview of what we include and our fixed fee, see our First Home Buyers service page.

What banks look for before they lend to you

Before a bank approves your mortgage, it assesses three things: your deposit, your ability to service the loan, and your credit history. Understanding each one helps you prepare.

Your deposit

Most banks require a minimum deposit of 10 to 20% of the purchase price. A 10% deposit is achievable for owner-occupiers with good income and credit history. A larger deposit reduces your loan-to-value ratio, which often unlocks lower interest rates and better terms.

If you cannot reach 10% from savings alone, your KiwiSaver balance can make up the difference. A family guarantor can sometimes remove the deposit requirement entirely (more on both below).

The Kainga Ora First Home Loan is a government-backed scheme that lets eligible buyers purchase with as little as a 5% deposit, underwritten by Kainga Ora so the bank takes less risk. Income caps apply and not all lenders offer it, but it is worth exploring early.

Your income, expenses, and debts

Banks calculate how much you can borrow based on your income minus your committed expenses: rent, car finance, credit card limits, student loan repayments, and regular outgoings. Your loan amount is essentially whatever the bank is satisfied you can service comfortably on your current income.

Reducing unnecessary debt before you apply (particularly credit card limits and buy-now-pay-later accounts) can meaningfully increase what you can borrow.

Your credit history

A clean credit history significantly improves your chances of approval. If you have defaults or missed payments on your record, address these before applying. It is worth checking your credit report at least six months before you plan to buy.

Using KiwiSaver to boost your deposit

If you have been contributing to KiwiSaver for at least three years, you can withdraw most of your balance to put toward your first home deposit. This can make a substantial difference. Many buyers withdraw $20,000 to $60,000 or more depending on how long they have been contributing.

KiwiSaver first home withdrawal: eligibility

0/0 complete

1. Contributing for at least 3 years
2. Buying to live in (not as an investment property)
3. Have not previously owned property in New Zealand (second-chance criteria may apply)
4. Have not used a KiwiSaver first home withdrawal before

Reset

You leave a minimum of $1,000 in your account. The rest can go toward your deposit.

You do not need to manage the application yourself. NZ Legal submits your KiwiSaver first home withdrawal as part of our conveyancing service. We liaise directly with your KiwiSaver provider, time the funds to land for settlement, and make sure nothing delays your purchase.

The Kainga Ora First Home Grant: what happened to it

Getting a guarantor involved

If your deposit falls short or your income does not quite meet the bank’s threshold, a family guarantor can be the difference between buying now and waiting another two years.

A family guarantor (usually a parent) puts up their own property or savings as additional security for your loan. This allows the bank to approve a larger amount, or to accept a smaller deposit from you, because the guarantor’s assets backstop the risk.

What the guarantor commits to: They are legally responsible for repaying the loan if you default. This is a serious obligation and every guarantor must understand what they are agreeing to.

Once you have built up enough equity, either through repayments or through property value growth, you can apply to the bank to release the guarantor from their obligations. The bank will want a current valuation and may require a formal review of your loan position.

The two legal documents that matter most

The sale and purchase agreement

This is the contract. It sets out the purchase price, the deposit amount, the settlement date, and any conditions. Standard conditions include finance (you have time to get your mortgage confirmed), due diligence (you can review the title and LIM), and sometimes a building inspection.

You should have your lawyer review this before you sign it. Once you sign and go unconditional, you are committed. We review the agreement, explain the conditions in plain English, and recommend any changes before your pen touches paper.

The record of title

The title tells you who legally owns the property, what mortgages or other charges are registered against it, and whether any easements, covenants, or consent notices affect the land. Some of these are innocuous; some are not.

A covenant may restrict what you can build. An easement may give a neighbour the right to cross your land. A consent notice may require specific drainage maintenance. We check each registered interest and tell you what it means for you as the owner.

Your rights as a buyer

The Real Estate Authority (REA) sets clear rules that real estate agents must follow. As a buyer you are entitled to honest answers about the property, to ask questions, and to conduct your own due diligence. Agents cannot mislead you or withhold material information.

Your responsibilities as a buyer include checking the physical condition of the property (building inspection), confirming any modifications were properly consented, and satisfying yourself on anything the title or LIM raises.

Due diligence is your window to investigate. Once you waive your conditions and go unconditional, what you have accepted is what you get. We guide you through what to check in the time you have.

What to look for in a property lawyer

Your lawyer does not just shuffle paperwork. They check the title before you commit, advise on any issues that surface, manage the KiwiSaver application, coordinate with your bank, prepare the transfer documentation, and get you to settlement day without surprises.

When choosing a property lawyer for your first home purchase, look for:

• A fixed fee. So you know the cost before you sign anything.
• Straight answers in plain English. Legal jargon that needs a dictionary is a red flag.
• Responsiveness. Your conditions have deadlines; you need a lawyer who is reachable.
• Specialist property experience. Conveyancing is not a side service here; it is what we do.
