RealyHow the NZ home buying process actually works (in plain English)
Most articles about buying a house in NZ assume you already know what an ADLS agreement is or what 'going unconditional' means. This guide doesn't. It walks through the whole process in the order it actually happens — what each step is, who's involved, how long it takes, and what you sign.
The big picture
Every NZ residential purchase follows the same five-act structure:
- Set up — get your money, your broker, and your lawyer in place. (2–6 weeks)
- Search — find a property you actually want to buy. (Weeks to months.)
- Offer & due diligence — make a conditional offer, then verify everything. (10–15 working days)
- Unconditional — waive conditions, deposit becomes payable. (Same day)
- Settlement — money moves, ownership transfers, you get keys. (Usually 4–6 weeks after going unconditional)
Act 1 — Set up (before you look at houses)
People involved: mortgage adviser, bank, lawyer.
You apply for pre-approval from a bank (via your adviser). The bank verifies your income and savings and issues a conditional commitment to lend up to a specific amount. You also choose a property lawyer at this stage — not after you've made an offer.
What you sign: loan application, AML/CFT identity verification with your lawyer.
Act 2 — Search
Listings appear on TradeMe Property and realestate.co.nz. Properties sell through four main methods:
- Negotiation / price by negotiation — make a conditional offer at any time.
- Auction — fixed date, you must bid unconditionally (no conditions allowed).
- Tender / deadline sale — submit a written offer by a fixed date.
- Set price — a fixed asking price.
The method massively changes the strategy and the cost-risk to you — auctions in particular require all due diligence before bidding.
Act 3 — Offer and due diligence
You sign a Sale and Purchase Agreement (the standard ADLS / REINZ contract) with conditions — usually finance, LIM, builder's report, title approval, and sometimes insurance pre-approval.
You then have a fixed window (typically 10–15 working days) to satisfy each condition. During this window:
- Your lawyer reviews the title and LIM
- The bank converts pre-approval into a formal loan offer
- A licensed building inspector produces a builder's report
- You arrange insurance (often a deal-breaker in flood / coastal zones)
What you sign: the SPA. Once signed, the seller is committed — but you can still walk away if a condition genuinely fails.
Act 4 — Going unconditional
You confirm in writing through your lawyer that all conditions are satisfied or waived. The deposit (typically 10% of the price) is paid to the agent's trust account that day.
From this moment you are legally bound. Pulling out costs the deposit at minimum and potentially damages.
Act 5 — Settlement
On settlement day:
- Your bank deposits the loan funds into your lawyer's trust account
- Your lawyer sends the full purchase price to the seller's lawyer
- The seller's lawyer confirms receipt and authorises the LINZ transfer
- The agent releases the keys
You bear the risk from the moment you sign unconditional but the house insurance must be active from 12:01am on settlement day.
What happens after you have the keys
In the first 30 days: change the locks, transfer utilities, update IRD and the electoral roll, register warranties on appliances or a new build, and take meter readings. Many councils require you to update the rates account in your name within a few weeks.
Frequently asked questions
How long does the whole NZ home buying process take?
End to end: usually 2–4 months. From accepted offer to settlement is typically 4–6 weeks. Auction-purchased homes can settle in 2–3 weeks; new builds may take many months.
What's the difference between conditional and unconditional in NZ?
A conditional offer has 'conditions' (finance, LIM, builder's report, etc.) that must be satisfied or waived. Until then either party can walk away if a condition fails. Going unconditional means all conditions are removed and you're legally committed to settle.
Do I need to be present at settlement?
No. Everything happens between your lawyer, your bank, and the seller's lawyer. You just collect the keys from the agent once settlement is confirmed.
Can I back out after signing the Sale and Purchase Agreement?
While conditional — yes, if a condition genuinely cannot be met (e.g. finance declined, major LIM issue). Once unconditional — only by forfeiting the deposit and potentially paying damages.
