What Counts Towards Your KiwiSaver Deposit

Working out how to calculate your KiwiSaver deposit for a house starts with knowing which parts of your balance you can actually use. Not every dollar in your account is available for a first home.

Your withdrawable balance is the portion of your KiwiSaver savings you can put towards a deposit. It includes your own contributions, your employer’s contributions, and any member tax credits you’ve earned.

But here’s the catch. Investment returns on those contributions are also included, which means the total can be higher than what you’ve personally put in.

So what gets left out?

• Australian superannuation transfers
• Any funds transferred from an overseas scheme
• Money you’ve already withdrawn

This matters because first-home buyers often assume their full balance is available. It isn’t. At Big Mike, we’ve walked plenty of Mid-Canterbury buyers through this exact step, and the gap between “my balance” and “my withdrawable balance” surprises almost everyone.

The good news is that your KiwiSaver provider will confirm the exact figure for you. You don’t have to guess.

KiwiSaver First Home Withdrawal Eligibility

KiwiSaver first home withdrawal eligibility comes down to three things: how long you’ve been a member, your balance, and whether you’ve owned a home before. Miss any one of these and the withdrawal won’t go ahead.

The Three-Year Membership Rule

You need to have been a KiwiSaver member for at least three years before you can withdraw for a first home. That clock starts from the day you joined, not the day you started contributing.

There’s some flexibility here. If you transferred from an overseas scheme, that time can sometimes count. Check with your provider.

Minimum Balance and Previous Home Ownership

You also need a minimum balance of $1,000 to make a withdrawal. That’s a low bar, but it catches people who’ve only just signed up.

The bigger test is home ownership. If you’ve owned property before, you’re generally locked out of the first-home withdrawal. There are exceptions for people in a similar financial position to a first-home buyer, so it pays to ask.

How to Calculate Your Withdrawable Balance Step by Step

Here’s the practical part. You can estimate your withdrawable balance yourself before your provider confirms it, and doing the maths early stops you falling for a house you can’t actually fund.

Step 1: Log Into Your KiwiSaver Account

Your provider’s app or website shows your current balance. Note the date, because the figure moves with the market.

Step 2: Separate Your Contributions From Transfers

Find your contribution history. Set aside any Australian superannuation transfers, because those sit outside the withdrawable total.

Step 3: Add Up Your Own, Employer and Government Contributions

These are all usable. Your own contributions, your employer’s contributions, and any member tax credits you’ve earned all count.

Step 4: Add Investment Returns

Returns on eligible contributions count too. This is why your withdrawable balance can be higher than what you’ve personally put in.

Step 5: Subtract Anything Already Withdrawn

If you’ve taken a hardship withdrawal before, that money is gone. It doesn’t come back into the calculation.

Step 6: Confirm With Your Provider

Your provider issues a formal withdrawal letter. Lenders want this, not your own maths.

A Worked Example for Our Community

Say your KiwiSaver balance sits at $48,000. Of that, $6,000 came from an Australian superannuation transfer, and you took a $2,000 hardship withdrawal two years ago.

Your withdrawable balance is roughly $40,000, the $48,000, minus the $6,000 transfer, minus the $2,000 already withdrawn. On a $600,000 house with a 20% deposit, that’s a $120,000 target, so you’d still need to cover the gap from savings, a First Home Grant, or a gifted deposit.

Run your own numbers with the official KiwiSaver first-home withdrawal guidance before you talk to a lender.

What Funds Are Included and Excluded

Fund Type	Counts Towards Deposit?
Your voluntary contributions	Yes
Employer contributions	Yes
Member tax credits	Yes
Investment returns	Yes
Australian superannuation transfer	No
Previous hardship withdrawals	No

The key takeaway: most of your balance is fair game, but overseas transfers are not.

Joint Purchases: Combining Two Withdrawals

If you’re buying with a partner, you can usually combine both withdrawals into the one deposit. Each person’s eligibility is assessed separately, so one buyer’s ineligibility doesn’t block the other.

Only one of you needs to qualify for the first-home withdrawal. The other can still be on the title. This trips up a lot of couples who assume both buyers must be eligible.

Self-Employed Buyers

If you’re self-employed, your contributions may be irregular. Your provider still counts them, but you’ll need clear records. Lenders also look harder at self-employed income, so sort your documentation early.

How to Apply for a KiwiSaver First Home Withdrawal

Knowing how to apply for a KiwiSaver first home withdrawal is simpler than it looks. You start with your provider, not the bank.

First, get a mortgage pre-approval or a signed sale and purchase agreement. Your lender or solicitor will need this before the provider releases funds.

Next, complete your provider’s withdrawal application form. Most providers have this online.

Then you’ll need a statutory declaration. This is a legal statement confirming you meet the first-home criteria. A solicitor or Justice of the Peace witnesses it.

Documents, Statutory Declaration and Solicitor Requirements

Expect to provide:

• Proof of identity
• Your sale and purchase agreement or pre-approval
• The statutory declaration
• Your provider’s completed form

Your solicitor usually handles the conveyancing side. They’ll confirm the funds go towards the property purchase on settlement date.

What Happens If the Purchase Falls Through

This is the scenario most guides skip, and it’s the one that catches buyers out.

If the sale falls over after your provider has released the funds, the money must go back into your KiwiSaver. You can’t keep it as cash, and you can’t redirect it to a different property without telling your provider.

Ring your provider straight away.

Tax Credits and Your Withdrawal

A common question is whether withdrawing affects your member tax credits. The short answer is no, the credits you’ve already earned stay yours, and withdrawing for a first home doesn’t claw them back.

Timeline and Deposit Shortfall

The KiwiSaver withdrawal process timeline usually runs five to fifteen working days, but it depends on your provider and how complete your paperwork is.

Here’s how it typically flows:

1. You submit your application and documents
2. Your provider checks eligibility
3. They confirm your withdrawable balance
4. Funds are released to your solicitor
5. Your solicitor applies them to the deposit

Frequently Asked Questions

How much of my KiwiSaver can I use for a house deposit?

You can withdraw most of your KiwiSaver balance for a first home, but you must leave at least $1,000 in the account. The withdrawable amount includes your own contributions, employer contributions, voluntary contributions and investment returns. Member tax credits are treated differently depending on when they were paid. Your KiwiSaver provider will confirm your exact withdrawable balance once you apply, so ask them for a figure before you make a conditional offer.

How do I apply for a KiwiSaver first home withdrawal?

Start by confirming your eligibility, then ask your KiwiSaver provider for the withdrawal form. You will need a sale and purchase agreement, proof of identity, and a statutory declaration signed in front of a solicitor or JP. Your solicitor handles the conveyancing side and confirms the funds go towards the deposit. Submit everything to your provider early, because the withdrawal must be processed before your settlement date.

How long does the KiwiSaver withdrawal process take?

Most providers take 10 to 15 working days to process a first home withdrawal once they receive a complete application. Missing documents are the main cause of delays, so check the paperwork before you send it. Build extra time into your timeline if your purchase has a short settlement date, and keep your lender informed so mortgage pre-approval stays valid.

Can I use my KiwiSaver for a deposit if I have owned property before?

Generally no, unless Kāinga Ora grants an exception. The first home withdrawal is designed for people who have never owned property, or who have not owned one for a set period. If you have owned before, you can still use your KiwiSaver when you reach 65. Talk to your provider about your contribution history and whether any exception applies to your situation before you rely on those funds.
