The question we hear most from first home buyers
If you’ve been saving for a while and keep asking yourself how much deposit for first home NZ lenders actually expect, you’re not alone. It’s usually the first question, and often the one that stalls people the longest. The good news is the answer isn’t as fixed as most people think.
There’s a standard rule, and then there are real options sitting underneath it. Once you understand both, it gets a lot easier to work out when you’re actually ready to buy, rather than guessing.
How much deposit for first home NZ buyers need from banks
Most home loan lenders in New Zealand ask for a minimum 20% deposit. That’s the baseline most banks build their lending policy around, and it’s where a lot of first home buyer conversations begin.
Twenty percent sounds simple until you put a real number against it. On an average Auckland house price of around $750,000, a 20% deposit works out to about $150,000. That’s not a small target for most people saving on a single income, or even two.
Anyways, that number isn’t the whole story. It’s the amount that gets you the best terms and the most choice of lender, but it’s not the only way in.
Low deposit options that get you there sooner
If 20% feels far away, there are genuine paths to buying with less.
The First Home Loan, backed by Kāinga Ora, allows some buyers to purchase with just a 5% deposit. Kāinga Ora underwrites the loan, which means a bank can accept a lower deposit than it normally would. There’s specific criteria to meet around income caps and property price caps, and not every bank offers it, so it pays to check which lenders participate before you get your hopes up around a particular property.
Some lenders will also consider a 10% deposit outside of the First Home Loan scheme, depending on your income, your spending, and the type of property you’re buying. New builds are often viewed more favourably at lower deposit levels than existing homes, which is worth knowing if you’re weighing up a new home construction option against buying established.
If you’re Māori and looking to build or buy on Māori land, the Kāinga Whenua Loan is a separate scheme worth asking about too, since standard deposit rules don’t apply in the same way.
Using your KiwiSaver towards the deposit
If you’ve been in KiwiSaver for at least three years, you may be able to withdraw your savings to put towards your first home deposit. You apply directly through your scheme provider, and there are rules around what portion of your funds you can access. If you’ve owned a home before but Kāinga Ora confirms you’re in the same financial position as a first home buyer, you may still qualify for this withdrawal too. It’s one of the most overlooked tools in a first home buyer’s deposit plan, so it’s worth checking early rather than leaving it to the last minute.
Why a mortgage calculator NZ borrowing power check comes first
Before you lock in a deposit target, it helps to know what you can actually borrow. A mortgage calculator NZ borrowing power tool gives you a rough idea, but it won’t account for the finer details banks look at, like your specific spending habits, existing debt, or how a particular lender treats your income type.
This is where the deposit question and the borrowing question meet. A bigger deposit reduces how much you need to borrow, but it also changes which banks will consider you and on what terms. We walk clients through both sides together, rather than looking at deposit in isolation, because the two numbers only make sense side by side.
Steps to work out if you’re ready to buy
If you’re trying to figure out where you actually sit, here’s a practical way to work through it.
- Add up your total savings, including any KiwiSaver funds you’d be eligible to withdraw, and treat that as your real deposit figure today.
- Check whether your income and the property price you’re considering fall within First Home Loan criteria, since this can open up the 5% deposit path.
- Get a clear read on your borrowing power based on your actual income and expenses, not just a rough online estimate.
- Compare how different banks treat your deposit size, your income type, and your employment situation, because policies vary more than most people expect.
- Set a realistic savings or KiwiSaver target based on the gap between where you are now and what a lender will actually approve.
If need be, this is also the point where speaking to someone independent makes a real difference, rather than relying on one bank’s view of your situation.
Why comparing banks matters more than people think
Each bank sets its own appetite for low deposit lending, and that appetite shifts depending on market conditions. One bank might be comfortable with a 10% deposit for a new build this month and tighten that policy next month. Another might offer better terms on a First Home Loan application than the bank you’ve already got a relationship with.
This is really the core of what an independent mortgage adviser in Auckland does. We compare options across the major banks rather than working for one, so you’re not stuck with whatever policy your everyday bank happens to run that week.
Please don’t wait for the “perfect” deposit
A lot of first home buyers hold off longer than they need to, aiming for 20% when a 5% or 10% deposit path was genuinely available to them months earlier. That delay can end up costing more in rent or rising prices than the extra saving ever saves.
