How to Buy a House in NZ: Where to Start, Step by Step

The Short Answer: Finance First, Then Everything Else

Buying a house in NZ runs in roughly six stages: get finance-ready, search with a real number in hand, do your due diligence on a property you like, make an offer, work through the conditional period, then settle. Most of the stress people associate with buying a house comes from doing these out of order.

The biggest one: house hunting before you know what you can actually borrow. It feels productive — you're out looking at places, you've got a Saturday morning routine going — but every offer you're tempted to make depends on a number you don't have yet. See our guide to how much you can actually borrow before you start looking, not after.

Settlement itself, once an offer's accepted and conditions are met, typically follows within 4–6 weeks. That's the shape of it. The detail is in what happens at each stage, and where people usually trip up.

Get Finance-Ready Before You Start Looking

Get your documents in order before you start house hunting, not after you've found the place. That's the single biggest delay I see in home lending — a borrower scrambling for payslips, bank statements, or two years of accounts once the bank conversation has already started.

Finance-ready means three things: knowing your deposit, knowing your income on paper rather than in your head, and getting pre-approved before you're standing in someone's living room picturing your couch in it. Pre-approval isn't a guarantee — the bank still checks the actual property once you've found one — but it makes your number real, to you and to whoever you're negotiating with.

It usually takes 3–5 business days once your documents are ready, sometimes less. That's not a big ask against the months the rest of the process can take. See our guide to mortgage pre-approval in NZ for exactly what a lender checks and what slows it down.

Search With a Number in Hand, Not a Wish List

Once you know what you can actually borrow, house hunting turns from guesswork into a filtered search. Set up alerts on the usual listing sites for your price range and area, and go look at more than the one property you're already half in love with — comparisons are what tell you whether a price is fair.

This is also where the deposit conversation gets specific. Ten to twenty percent is the standard range for an owner-occupier, five percent if you're an eligible first home buyer through the Kāinga Ora-backed First Home Loan, and thirty-five percent if you're buying to rent it out. Our full guide to home loan deposits in NZ covers where that money can actually come from.

A property that ticks every box on your wish list but sits outside your pre-approved number isn't a find. It's a longer conversation with your bank.

LIM Report and Building Inspection: Different Jobs, Both Necessary

Once you've got a property in mind, two reports do different jobs, and skipping either one because you're keen to move fast is the "yada yada yada" version of buying a house — you've glossed over the exact part that mattered.

A Land Information Memorandum, or LIM, comes from the local council. It covers consents, notices, rates, and any recorded natural hazards on the property. It won't catch everything — unconsented work doesn't always make it onto council records — which is exactly why the second report matters.

A building inspection is an independent, hands-on look at the property's actual condition: structural issues, moisture, maintenance the listing photos didn't mention. It's worth the cost on any property, new or old — a professional inspection catches things a walkthrough on a Saturday afternoon never will.

Both reports usually sit inside your conditional period, alongside finance. See the Real Estate Authority's guide to the home buying process for what each one covers in more depth.

Making an Offer, and the Conditional Period That Follows

How you make an offer depends on how the property's being sold. A private treaty or tender sale lets you make a conditional offer — subject to finance, a building report, a LIM, whatever you and your lawyer agree to include. An auction is unconditional the moment the hammer falls, which is a thrilling way to find out your building report should've happened last week.

That's the part people underestimate about auctions: the conditional period doesn't disappear, it just moves earlier. You're doing the same due diligence, on the same timeline, with less certainty about whether you'll actually need it.

Assuming you've bought conditionally, the conditional period is usually where finance, building report, and LIM conditions all get satisfied — commonly negotiated at somewhere between ten and twenty working days, though the exact window sits in the agreement itself, not fixed by law. Once every condition's been met or waived in writing, the agreement goes unconditional. At that point, you can't walk away without a real legal reason, even if your feelings about the kitchen change.

This is where a pre-approval that's already in place, rather than one you're starting from scratch, is the difference between a calm conditional period and a stressful one.

Settlement Day, and the Costs Nobody Mentions First

Settlement itself, once every condition is met, usually happens within 4–6 weeks of your offer being accepted. Your lawyer handles the transfer, your lender releases the funds, and the keys change hands — by the time you're picking them up, most of the actual work already happened weeks earlier.

Budget for more than just the deposit. Legal fees, the LIM report, the building inspection, insurance from the day you go unconditional, and the cost of actually moving all sit on top of the purchase price. Your solicitor will give you an exact figure for your specific purchase — ask for it early, not the week before settlement, so it's not a surprise sitting next to a number you'd already mentally spent.

Insurance is worth flagging on its own: most lenders won't release funds on settlement day without it in place, and insurers can take longer than people expect during quieter periods. Sort it as soon as you're unconditional, not the morning of.

Why This Is Easier With the Right Adviser

Before AML, I ran a few small businesses — restaurants, and for a stretch, a taxi. I know what it feels like when a bank's decision changes the direction of a family's plans, and I know the difference between yes and no is rarely just about the numbers. It's about whether the application's prepared properly and whether whoever's lodging it understands what the bank's actually checking. That's why I started AML in 2017: an adviser who's sat on the other side of a decision, not just handed out forms.

Every step above — the pre-approval, the LIM, the building report, the conditional period — moves faster when someone's already run it a few hundred times. We've settled 200+ home loans since 2017, across 20 banks and non-bank lenders on panel — 7 banks, 13 non-bank — and we reply within 2 business hours, not whenever someone gets around to it.

There's no fee for that first conversation. In the typical case, the lender pays us once your loan settles, and we tell you exactly how before anything's lodged. AML Financial Services Limited is a licensed Financial Advice Provider — FSP 714331. Worth checking for any adviser you're talking to, not just us.

Buying a house isn't hard because any one step is difficult. It's hard because you're doing five unfamiliar things at once, for the first time, with your own money on the line. Get the finance step right first, and the rest gets a lot less dramatic. See our page for first home buyers, or call us before your open-home Saturdays turn into a part-time job.
