5% Deposit for First Home Buyers NZ: Who Could Benefit From the Proposed 2026 Changes?

A lower deposit could widen the door, but it does not remove the lending test.

New Zealand already has a Kāinga Ora-backed First Home Loan that can allow eligible buyers to purchase with a minimum 5% deposit. The main proposed 2026 change is to widen access by lifting the scheme's income cap to $300,000.

Quick answer Buyers most likely to benefit are people who can afford mortgage repayments but have struggled to build a 20% deposit, particularly single professionals and dual-income households whose earnings are above the current First Home Loan income limits.

That distinction matters. A 5% deposit can reduce the upfront cash hurdle significantly, but it usually means borrowing more. Lenders will still assess income, expenses, existing debt, credit history and whether the proposed repayments are sustainable.

What is being proposed for the First Home Loan?

At the time of writing, the current Kāinga Ora income limits remain in place. National has proposed lifting the First Home Loan income cap to $300,000 for applicants if re-elected.

Current vs proposed income limits

Simple comparison, always check final scheme rules before applying.

2026 proposal

Single buyer, no dependants	$95,000	Current maximum annual before-tax income	Proposed: $300,000
Single buyer, with dependant(s)	$150,000	Current maximum annual before-tax income	Proposed: $300,000
Two or more buyers, combined	$150,000	Current maximum combined annual before-tax income	Proposed: $300,000

The First Home Loan itself is not a cash grant. It is a low-deposit home-loan pathway administered by Kāinga Ora and offered through participating lenders. Eligible buyers still need a minimum 5% deposit and must meet both scheme criteria and the lender's own approval requirements.

How much is a 5% house deposit in NZ?

For many first-home buyers, the most striking part of the policy discussion is the difference between saving 5% and saving 20%. Use the interactive example below to see the numbers.

Illustrative deposit amounts only, excludes fees, insurance and other purchase costs.

On an $800,000 purchase, the difference between a 5% and 20% deposit is $120,000. That could materially shorten the time some households need to save. However, a lower deposit also means a larger mortgage, approximately $760,000 before any fees or premiums in this example.

The buyers most likely to benefit from a wider 5% deposit pathway

No policy helps every buyer equally. The strongest beneficiaries are likely to be people whose main barrier is the size of the deposit rather than the ability to service a mortgage.

Dual-income couples above today's cap

Households earning more than $150,000 combined may currently be excluded even when their repayment capacity is relatively strong.

Single professionals

A single buyer earning above the current $95,000 limit could become eligible under a much higher proposed cap, subject to final rules.

Renters with solid incomes but slower savings

High rent and everyday costs can make building a 20% deposit difficult even when monthly mortgage repayments may be manageable.

Buyers using KiwiSaver toward the deposit

Eligible first-home withdrawals can form part of a deposit, which may bring the 5% threshold within reach sooner.

Buyers in higher-priced markets

In markets such as Auckland, the gap between 5% and 20% can represent well over $100,000 on many entry-level homes.

Buyers who could purchase sooner

If deposit savings are the only major hurdle, a lower minimum could bring a purchase forward, but only if the mortgage remains affordable.

Who might still miss out, even with a 5% deposit?

A lower deposit requirement does not guarantee approval. The scheme and participating lenders still apply eligibility, credit and affordability checks.

What the change could solve

• A deposit target that feels years away
• Current income caps excluding otherwise capable buyers
• The upfront gap between 5% and 20%
• Difficulty entering the market while paying high rent

What it does not automatically solve

• Insufficient borrowing power
• High consumer debt or poor credit history
• Mortgage repayments that fail servicing tests
• Ongoing homeownership costs such as rates and insurance
• Eligibility rules for owner-occupation and property ownership

Current First Home Loan criteria also include purchasing the home as your primary residence, not owning other property or land (with limited exceptions such as Māori land), and buying a property under one hectare. Kāinga Ora also lists a lender's mortgage insurance premium and potential lender application fees.

Could wider access to 5% deposits push house prices up?

It is possible that broader access to low-deposit lending could add demand at the margin, particularly in first-home-buyer price brackets. But it would be too simplistic to assume the policy alone will make prices rise.

• Demand Buyer numbers & competition
• Rates Mortgage affordability
• Supply Listings & new housing
• Credit Lender servicing rules

House prices are influenced by many factors at once: interest rates, wages, credit settings, available listings, new housing supply, migration and buyer confidence. A policy that helps more people assemble a deposit may increase the pool of potential buyers, while lender affordability tests can still limit how much those buyers can bid.

Useful way to think about it The proposal mainly targets the deposit barrier. It does not remove the borrowing-power barrier or the repayment-affordability barrier.

Should first-home buyers wait for the policy change?

Not necessarily. Because the proposed $300,000 cap is not currently in force, buyers should make decisions based on their present financial position and current lending rules rather than assuming a future policy will apply to them.

Check your current deposit

Include genuine savings and, where eligible, KiwiSaver first-home withdrawal funds and permitted gifts.

Understand your borrowing power

A lender or mortgage adviser can help estimate what you may actually be able to borrow under current servicing tests.

Compare 5%, 10% and 20% scenarios

Look beyond the deposit and compare loan size, repayments, interest costs, insurance premiums and emergency savings.

Watch for final policy details

If the proposal progresses, confirm commencement dates, eligibility requirements and participating lenders before relying on it.

Search for homes within a comfortable budget

Start with what you can sustainably afford rather than the maximum amount a lender may approve.
