Buying a home in New Zealand for $700,000 with a 10% deposit means you need $70,000 for the deposit, but the total cash you need on settlement day is closer to $80,000–$82,000 once legal fees, inspections, insurance, and moving costs are added in. That extra $10,000–$12,000 is easy to miss if you are only focused on the deposit.

Most first-home buyers in New Zealand know they need a deposit. What catches them out is the stack of costs that sit on top of it — legal work, council reports, insurance, and the first round of repairs. These costs add up to a meaningful second deposit of their own. Here’s what you actually need to know.
When you buy a home in New Zealand, the price you agree on is only part of the story. The term that covers everything else is settlement costs — the fees and payments that must be completed before the property legally changes hands. These include legal fees, council reports, lender charges, and insurance. What I tend to notice is that buyers who separate “deposit money” from “settlement money” in their bank accounts from day one rarely get caught short.
What the full cost of buying a home in New Zealand actually looks like
The purchase price is the headline number. The real number is higher, and it varies by region, property type, and how you buy. A standard breakdown for a $700,000 home bought with a 10% deposit looks like this.

| Cost category | Typical range | When it’s paid |
|---|---|---|
| Deposit (10%) | $70,000 | Settlement day |
| Legal and conveyancing fees | $1,500–$3,500 | Settlement day |
| Building inspection | $500–$900 | Before offer or during due diligence |
| LIM report | $300–$450 | Before offer or during due diligence |
| Registered valuation | $600–$1,200 | Before settlement (lender may require) |
| Mortgage application fee | $0–$500 | At loan approval |
| Home and contents insurance (first year) | $1,500–$3,000 | Before settlement |
| Moving costs | $500–$3,000 | Around settlement day |
| Immediate maintenance and repairs | $500–$5,000+ | First month after moving in |
| Furnishings and appliances | $2,000–$15,000 | First month after moving in |
Add it up and the total cash requirement on a $700,000 home with a 10% deposit is roughly $80,000–$82,000. That extra $10,000–$12,000 is not a buffer — it is a fixed cost. The range shifts depending on where you buy. Council rates in Auckland run $2,000–$4,000 a year, while Wellington and Christchurch are similar. Insurance costs more in flood-prone or earthquake-prone zones. Worth weighing against the idea that a 5% deposit is enough — it is, but only if you have the other 10–12% in cash for everything else.
Where first-home buyers in New Zealand get the numbers wrong
Skipping the building inspection to save money
A building inspection costs $500–$900. Skipping it can cost six figures. Lenders also require a satisfactory inspection report before approving the loan on some property types. If you buy at auction without one and discover structural issues later, you own the problem. The inspection is not optional — it is a condition of most standard loan approvals. My first move would be to budget for inspections on at least two or three properties, especially if bidding at auction where due diligence costs are non-refundable.
Going unconditional without written bank approval
Verbal approval from a lender is not enough. If you go unconditional on a sale and the bank withdraws the offer after a final credit check or valuation, you forfeit your deposit. The process is: get pre-approval (valid 60–90 days), then submit the full application with the signed sale and purchase agreement, then wait for the lender’s formal unconditional letter before removing your finance condition. Skipping that step risks the entire deposit.
Underestimating the first year of ownership
First-year costs — insurance, rates, immediate repairs, furnishings — run $4,000–$9,000 on top of the purchase costs. A common mistake is treating the deposit as the finish line. The reality is that settlement day is the start of a new monthly budget that includes rates ($2,000–$4,000 a year), insurance ($1,500–$3,000), and maintenance. If you have not set aside money for a leaking roof or a failed hot water cylinder in month one, you are borrowing at credit card rates to fix it.
Not understanding the Kāinga Ora income and price caps
The Kāinga Ora First Home Loan and Grant have specific limits. As of 2026, the income cap is $95,000 for a single buyer and $150,000 for two or more buyers. Regional price caps also apply — a $700,000 home might qualify in one region but not another. If you assume you qualify without checking the caps, you could structure your offer around a grant that does not exist. The application process requires a solicitor’s certificate and takes 10–20 business days. Apply before you make an offer, not after.
How to budget for a home purchase in New Zealand, step by step
Step one: get your KiwiSaver and Kāinga Ora numbers locked in
Check your KiwiSaver balance and confirm you have been a member for at least three years. You can withdraw most of your balance but must leave $1,000 in the account. The application goes through your solicitor and takes 10–20 business days — submit it as soon as your offer goes unconditional. For the Kāinga Ora First Home Grant, you can get up to $10,000 for an existing home or $20,000 for a new build per eligible member. Apply before you make an offer, because the grant cannot be added retroactively. If you need help understanding the eligibility rules, a service like JustAnswer Real Estate Law can clarify the fine print on income caps and regional limits.
Step two: get pre-approval and understand your LVR
Pre-approval shows sellers you are serious and tells you exactly how much you can borrow. It is typically valid for 60–90 days. Lenders look for 3–6 months of genuine savings history — regular deposits into a savings account, not a sudden lump sum. The minimum deposit is 5% with a Kāinga Ora First Home Loan, but most standard loans require 20% to avoid low-equity fees. The LVR (loan-to-value ratio) rules set by the Reserve Bank mean not all lenders offer 95% LVR loans to all borrowers. A mortgage adviser can help match you to a lender that offers the LVR you need.
Step three: budget for every pre-purchase report
Before you make an offer, you need a building inspection ($500–$900), a LIM report ($300–$450), and possibly a registered valuation ($600–$1,200) if your lender requires it. The LIM report reveals encumbrances, unpermitted work, and compliance issues — problems that could block your loan or cost thousands to fix. If you are buying at auction, these costs are non-refundable if you lose the bid. Budget for two or three rounds of inspections if you expect to bid multiple times.
Step four: plan for settlement day and the first month
Settlement day is when the money moves. Your KiwiSaver withdrawal, Kāinga Ora grant, and loan funds all arrive in your solicitor’s trust account. The solicitor pays the seller, the property transfers to your name, and you get the keys. Home insurance must be active before settlement — lenders require proof of full replacement cover. Moving costs run $500–$3,000. Immediate maintenance and furnishings add another $500–$5,000. If you are buying an older home, a home inspection checklist book can help you spot issues early and avoid surprise repair bills in the first month.
What is changing: upcoming regulatory shifts that affect costs
The Reserve Bank reviews LVR settings regularly, and changes can tighten or loosen deposit requirements. The Kāinga Goa income and price caps are also reviewed periodically — what qualifies today may not qualify next year. If you are planning to buy more than six months out, check the current caps and LVR rules before you start saving. A shift in either direction changes how much cash you actually need.

The real cost of buying a home in New Zealand is the one you plan for
The difference between a smooth purchase and a stressful one is knowing exactly how much cash you need before you start looking. The deposit is the headline number, but the $8,000–$15,000 in hidden costs is what determines whether settlement day goes ahead without a last-minute scramble. Budget for the full picture, not just the price tag.
