Buying Your First Home in NZ: What the Bank Won't Walk You Through

Buying your first home in New Zealand is one of the biggest financial steps most people take — and also one of the least explained. Banks will tell you whether you qualify for their loan. What they don't always do is walk you through the parts that sit around the loan: how to structure it against your short and long-term goals, which government-backed tools you can use, and why a "yes" from one lender isn't the same as a "yes" from another.

This guide covers what a first home buyer in NZ needs to understand before signing anything — in plain language, with the current rules as they stand.

How much deposit do you really need?

The figure most people have heard is 20%. For existing homes bought through a main bank, that's broadly the benchmark: the Reserve Bank of New Zealand (RBNZ) classifies an owner-occupier loan as "high-LVR" once you're borrowing more than 80% of the property's value, which means a deposit under 20%. Banks are limited in how much high-LVR lending they can do, so a 20% deposit gives you the widest choice and the sharpest rates. It's worth knowing that at some points through the year, a bank's capacity for high-LVR lending can be used up — meaning even a strong application under 20% might have to wait.

But 20% is not the only path. Two things change the picture for owner-occupier buyers:

Low-deposit lending. Banks are allowed to write a share of their lending to buyers with smaller deposits. Many lenders will consider a 10% deposit, though it often comes with a "low-equity premium" — a small interest loading that comes off once your loan drops below 80% of the property's value. This isn't limited to first home buyers; most banks will look at 10% for owner-occupiers more generally.

New builds. Brand-new homes are largely exempt from RBNZ deposit restrictions, which is why some buyers can purchase a new build with as little as 5–10% down without using up the bank's limited low-deposit quota. This exemption applies to owner-occupiers and investors alike, not just first home buyers.

The deposit you need, in other words, depends on what you're buying and which lender you're with. That's exactly the kind of thing worth checking before you fall in love with a listing.

What is the First Home Loan?

The First Home Loan is a government-backed scheme administered by Kāinga Ora. It lets eligible first home buyers purchase with as little as a 5% deposit, because these loans are exempt from the usual bank deposit restrictions.

It's not available everywhere — only through participating lenders (currently a handful of banks and non-bank lenders) — and it comes with income caps and other criteria. But for buyers who are close on income and short on deposit, it can be the difference between buying this year and waiting another two.

One important note: the First Home Grant — the cash top-up some buyers may remember — closed to new applications in May 2024 and is no longer available. If you come across older articles mentioning it, check the date. The KiwiSaver first-home withdrawal and the First Home Loan are the two main government-backed tools still in place.

Using your KiwiSaver for your first home

If you've been contributing to KiwiSaver for at least three years, you can usually withdraw most of your balance to put towards a first home. The rules are straightforward:

• You must have been a member for at least three years.
• You must leave at least $1,000 in your account.
• The property must be one you intend to live in — not an investment.
• You can generally withdraw your contributions, your employer's contributions, the government contributions, and your investment returns. Funds transferred from an Australian super scheme can't be withdrawn.

You apply through your KiwiSaver provider, not Inland Revenue or Kāinga Ora (unless you've owned property before, in which case Kāinga Ora assesses your eligibility first). The money is paid to your solicitor, not to you — and it's worth starting the paperwork four to six weeks before settlement, because it takes time to process.

For many first home buyers, KiwiSaver is the single largest piece of the deposit. Knowing exactly how much you can access — and when — shapes everything else.

One timing trap worth knowing

Here's a wrinkle that catches people out: for a lot of first home buyers, the entire deposit comes from KiwiSaver. But your KiwiSaver funds aren't released until settlement — while a sale and purchase agreement usually asks for a deposit the moment you go unconditional, well before settlement day.

There are two common ways around this, and both are worth sorting early. Your solicitor or agent can include a condition in the sale and purchase agreement so the deposit is only payable once your KiwiSaver provider releases the funds on settlement. Alternatively, an adviser can help arrange a short-term overdraft to bridge the gap. Neither is complicated — but it's much easier handled before you sign than scrambled together afterwards.

Pre-approval vs approval: why the difference matters

This is the step that trips up the most people, and it's where a lot of stress comes from.

Pre-approval (sometimes called conditional approval) is a lender's indication of how much they'd likely lend you, based on your income, deposit, and a credit check. It's enough to let you bid or make offers with confidence — but it usually comes with conditions, and it's not a final commitment.

Approval (unconditional approval) is the lender confirming the loan against a specific property — once they've seen the sale and purchase agreement, a valuation if required, and confirmed the property itself is acceptable security.

How long a pre-approval lasts depends on your deposit. When you're borrowing under 80% of the property's value, a pre-approval is typically valid for around 90 days. When you're over 80% LVR, it's a different story: some banks won't issue an open pre-approval at all, and will only assess you against a specific property once you've made an offer — sometimes called a "live deal." Where a shorter pre-approval is offered on high-LVR lending, it often runs closer to 60 days. It's one more reason your deposit position shapes far more than just the interest rate.

The gap between pre-approval and unconditional approval is where deals can wobble: a pre-approval might assume a deposit you haven't fully confirmed, or a property that turns out to need a registered valuation. Understanding that pre-approval is a starting point, not a finish line, is one of the most useful things a first home buyer can know.

Where a mortgage adviser fits in

This is the part the bank can't do for you — because a bank can only offer you its own products.

A mortgage adviser works across multiple lenders. At DormFIN, Riaan Wilson brings more than 29 years of banking experience across New Zealand and South Africa to exactly this kind of situation. Rather than fitting you to one bank's criteria, an adviser's job is to look at your full picture — deposit, KiwiSaver, income, the type of property you're after — and work out which lender and which structure actually suits your short and long-term goals.

For a first home buyer, that means:

• Checking which lenders will take your deposit situation, including First Home Loan eligibility.
• Structuring the loan itself — not just securing it — so it fits where you want to be in five, ten, twenty years, not only where you are today.
• Making sure your KiwiSaver withdrawal is timed correctly against settlement, and the deposit gap is handled before you sign.
• Explaining the conditions on a pre-approval before they become a problem.
• Handling the back-and-forth with the lender so you're not doing it alone.

None of this replaces your own decisions. It just means you're making them with someone who does this every day, rather than working it out as you go.

A calmer way to start

Buying a first home in NZ involves a lot of moving parts — deposit rules, KiwiSaver timing, the difference between a maybe and a yes. The good news is that none of it has to be worked out in one go, or on your own.

If you're starting to think about your first home, a conversation early — before you're under pressure on a specific property — tends to make the whole process clearer. You can learn more about how DormFIN approaches home loans here, or get in touch to talk through where you're at.
