How Much KiwiSaver for a House Deposit in NZ (2026)

Your real KiwiSaver deposit is your withdrawable balance minus the $1,000 you must leave behind and any excluded Australian-super funds. Here is how to work out your true number by settlement.

Your online KiwiSaver balance and the amount you can actually put toward a deposit at settlement are not the same number. The provider statement shows everything, but the withdrawal rules carve a piece out, and a slice of that money may not be eligible at all. It is common to over-estimate a deposit by between $1,000 and several thousand dollars, and the difference often only becomes clear when the solicitor confirms the figure days before settlement.

This guide shows you how to calculate your real, withdrawable KiwiSaver deposit, what the deposit target looks like across New Zealand in 2026, and how the 5% First Home Loan changes the maths entirely.

TL;DR: Your real KiwiSaver deposit is your withdrawable balance minus the $1,000 you must legally leave in your account, minus any funds transferred from an Australian super scheme, capped at the purchase price. On a $775,000 national median home, a 5% First Home Loan deposit is about $38,750; a standard 20% deposit is about $155,000.

What part of your KiwiSaver can go toward a deposit?

For a first-home withdrawal you can take out almost everything: your own contributions, your employer's contributions, the government contributions, and the investment returns earned on all of it ¹. That is the good news, and it is why KiwiSaver does so much of the heavy lifting for first-home buyers.

The rules then carve out two pieces:

• You must leave at least $1,000 in the account. This is non-negotiable and keeps your KiwiSaver membership alive ¹.
• Any funds transferred from an Australian complying superannuation scheme cannot be withdrawn for a first home. If you have worked in Australia and brought your super across, that portion is excluded on top of the $1,000 ².

There is also a ceiling: the withdrawal is capped at the purchase price in your sale and purchase agreement ². You cannot pull out more than the house costs.

So the formula for your real deposit is simple:

Withdrawable balance − $1,000 − any Australian-super transfer = your KiwiSaver deposit

You can model your own figure in our first-home deposit calculator, or have us confirm it as part of a free KiwiSaver first-home health check.

The eligibility rules that trip people up

Two conditions catch buyers off guard close to settlement:

• You must have been a KiwiSaver member for at least 3 years, and you must intend to live in the property ³.
• You can only make a first-home withdrawal once. A withdrawal you used for the deposit cannot be repeated at settlement ³. KiwiSaver does not top up again on settlement day. Whatever you take for the deposit is the money you have, and the rest of the purchase price has to come from your mortgage and other savings.

A worked example

Scenario: Aroha has been in KiwiSaver for 6 years. Her balance is $46,800, of which $4,200 was transferred from an Australian super fund when she moved home from Brisbane.

Aroha thought she had $46,800 to work with. Her actual deposit is $41,600 — a $5,200 difference, large enough to change which homes she can offer on.

How much deposit do you need in NZ in 2026?

The headline number depends entirely on which deposit pathway you use.

The REINZ national median house price in the May 2026 property report was $775,000 ⁷. On that figure:

The gap between those two columns — roughly $116,000 — is the difference between buying this year and saving for another five. For most first-home buyers, KiwiSaver gets you comfortably to a 5% deposit but nowhere near 20%. That is precisely the problem the First Home Loan was designed to solve.

How do regional house prices change your deposit target?

A national median is useful for a headline but useless for a buyer in a specific city. Your real target depends on where you are buying. Using the REINZ May 2026 national median ($775,000), the Auckland median ($975,000), and the ex-Auckland median ($700,000) ⁷, here is what the deposit looks like at each pathway:

In Canterbury, where the May 2026 median hit a record $725,000 ⁷, a 5% deposit of roughly $36,000 is achievable for many couples with two reasonable KiwiSaver balances. In Auckland, the same 5% pathway still asks for close to $48,750, which is why Auckland buyers lean harder on combined balances, gifts, and a longer save.

What is the First Home Loan 5% deposit pathway?

The Kāinga Ora First Home Loan lets eligible first-home buyers purchase with a minimum 5% deposit instead of the standard 20% ⁴. The loan is offered through participating banks, building societies and credit unions and is underwritten by Kāinga Ora, which is why a lender can approve it with a smaller deposit than they would normally accept.

There are income caps. Your before-tax income over the last 12 months must be:

Two things worth knowing before you bank on this pathway:

• There is a one-off Lender's Mortgage Insurance premium of 1.2% of the loan amount, payable upfront or added to the loan ⁶. On a $736,250 loan (a $775,000 home with a 5% deposit) that is roughly $8,835. This premium sits on top of your deposit, so build it into the gap you plan for in the [deposit-readiness checklist](#your-deposit-readiness-checklist) below rather than treating the 5% deposit as your only upfront cost.
• There are no longer any regional house price caps — those were removed in 2022 — so any property price is allowed as long as you meet the income caps and the lender approves servicing ¹³.

Which lenders offer it?

The First Home Loan is delivered through participating lenders, not directly by Kāinga Ora. Lenders commonly cited as participating include:

Loans are underwritten by Kāinga Ora. Confirm current participation and servicing criteria directly with the lender ⁴.

Being eligible for a 5% deposit is not the same as a bank approving the loan. Servicing — whether your income covers the repayments at the bank's test rate — still has to stack up. A first-home KiwiSaver review covers both the deposit and the servicing side across the participating lenders.

Why low-deposit buyers need a stronger protection plan

The smaller your deposit, the larger your mortgage relative to the home's value — and the more exposed you are if your income stops.

A buyer with a 5% deposit owes 95% of the purchase price from day one. If you lose your income to illness or injury for even a few months, there is no equity buffer to lean on, and the mortgage payments do not pause. A 20%-deposit buyer has room to sell down or refinance in a crisis; a 5%-deposit buyer often does not.

For this reason, mortgage protection is best treated as part of the deposit planning, not a separate step. The two products that matter most for a new low-deposit owner are income protection (to keep paying the mortgage if you cannot work) and a level of life or trauma cover that clears or reduces the loan. You can read how this fits together in our mortgage protection guide.

The time to build the protection plan is when your offer is accepted, not after something goes wrong.

How do you close a deposit gap before settlement?

If your KiwiSaver-plus-savings number lands short of your target, you usually have a few levers — but most of them work slowly, so start early.

Maximise the government contribution. From 1 July 2025 the KiwiSaver government contribution was halved to 25 cents per $1 contributed, up to a maximum of $260.72 a year; you need to contribute at least $1,042.86 in the year to 30 June to receive the full amount ⁸. It is smaller than it used to be, but it is still free money toward your deposit. Note: members with annual taxable income over $180,000 are no longer eligible for any government contribution ⁹.

Lift your contribution rate. The default minimum employee and employer rate rose from 3% to 3.5% on 1 April 2026 and is scheduled to rise to 4% on 1 April 2028 ¹⁰. You can voluntarily contribute more on top, which is one of the fastest ways to grow a deposit if you have surplus income.

Check your PIR — a low-income saver often overpays tax. If you do not give your provider a Prescribed Investor Rate, your PIE income is taxed at the default 28% ¹², even if you should be on a lower rate. The thresholds are:

Source: IRD PIR guide IR861, tax year ending 31 March 2026 ¹¹; default 28% per IRD ¹². Your PIR is based on the lower result of the previous two income years.

Younger first-home savers are often on 28% when they should be on 17.5% or even 10.5%. Fixing it does not transform a deposit, but over a two- or three-year save it keeps real money in the account instead of sending it to IRD.

Mind your fund choice as settlement nears. A deposit you plan to withdraw inside three years generally does not belong in a growth fund, where a market dip at the wrong moment can shrink your deposit right before you need it. Conservative and cash funds are built for short horizons. You can compare current annual fees and returns for every fund — Simplicity, Kernel, Booster, ASB, Milford and the rest — on the FMA/Sorted Smart Investor fund finder.

Your deposit-readiness checklist

1. Confirm your real withdrawable balance. Take your total, subtract $1,000 and any Australian-super transfer. That is your number, not the app figure.

2. Check you meet the 3-year membership and owner-occupier rules ³. If you are short on membership time, you know your earliest possible withdrawal date.

3. Pick your deposit pathway. 5% via the First Home Loan, or 20% standard. Run both against your regional median.

4. Test the income caps and servicing. $95,000 single / $150,000 with dependants or 2+ buyers for the First Home Loan ⁵, and the bank's servicing test on top. Remember the one-off 1.2% Lender's Mortgage Insurance premium ⁶ sits on top of the deposit.

5. Set your fund to match your timeline. Withdrawing inside three years usually means conservative or cash, not growth.

6. Build the protection plan before settlement. Income protection and loan-clearing cover, sized to a highly geared mortgage.

Frequently asked questions

How much of my KiwiSaver can I use for a house deposit? Almost all of it — your contributions, your employer's, the government contributions and investment returns — but you must leave at least $1,000 in the account, and any funds transferred from an Australian super scheme cannot be withdrawn ¹². The withdrawal is also capped at the purchase price in your sale and purchase agreement ².

Do I get a second KiwiSaver withdrawal at settlement? No. You can only make a first-home KiwiSaver withdrawal once, so a deposit withdrawal cannot be repeated at settlement ³. Whatever you take for the deposit is the money you have toward the purchase from KiwiSaver.

How much deposit do I need to buy a first home in NZ in 2026? On the REINZ May 2026 national median of $775,000, a 5% First Home Loan deposit is about $38,750 and a standard 20% deposit is about $155,000 ⁷. Your real target depends on the median price in the region you are buying in.

What is the 5% First Home Loan and who qualifies? It is a Kāinga Ora-underwritten loan offered through participating lenders that lets eligible first-home buyers purchase with a 5% deposit ⁴. Your before-tax income over the last 12 months must be $95,000 or less (single, no dependants) or $150,000 or less (single with dependants, or two or more buyers combined) ⁵. A one-off Lender's Mortgage Insurance premium of 1.2% of the loan applies ⁶, and there are no longer any house price caps ¹³.

Should I switch my KiwiSaver fund before I buy? If you plan to withdraw within about three years, a growth fund exposes your deposit to a market fall at the worst possible time. Many buyers move to a conservative or cash fund as settlement approaches. Compare current fund fees and returns on the Smart Investor fund finder, and talk to an adviser about timing.

Why does a small deposit mean I need more insurance? A 5% deposit means you owe 95% of the home's value with almost no equity buffer. If your income stops, the mortgage payments do not. Income protection and loan-clearing life or trauma cover are what keep a highly geared first home safe — see our mortgage protection guide.
