Buying a property in New Zealand involves a specific legal and financial process that differs significantly from other countries. Understanding each stage — from finance pre-approval through to settlement — helps you move confidently, avoid costly mistakes, and protect yourself against hidden risks.
This guide walks through the complete process in the order you’ll experience it.
Overview: The House Buying Journey
| Stage | Typical timeframe |
|---|---|
| Get finances ready | 2–6 months before buying |
| Pre-approval | 1–2 weeks before searching |
| Property search | Weeks to months |
| Due diligence | 5–15 working days |
| Signing agreement and going unconditional | 5–15 working days after finding property |
| Settlement | 1–8 weeks after unconditional |
| Moving in | Settlement day |
Stage 1: Get Your Finances Ready
Before you start looking at properties, understand your financial position:
Know your borrowing capacity
Use our mortgage affordability calculator or speak to a bank or broker to understand how much you can borrow. This gives you a realistic budget.
Key factors banks assess:
- Gross household income
- Living expenses and committed liabilities
- Deposit amount (including KiwiSaver)
- Credit history
Prepare your deposit
Standard requirement: 20% of the purchase price. Through the Kāinga Ora First Home Loan: 5% for eligible buyers.
If you’re using KiwiSaver, apply for your first home withdrawal at the same time as your mortgage application.
Check your credit file
Obtain a free credit report from Centrix, Equifax, or illion. Dispute any errors — even a small old default can complicate an application.
Stage 2: Get Mortgage Pre-Approval
Before actively searching for a property, get mortgage pre-approval (conditional approval). This tells you:
- Exactly how much you can borrow
- What conditions the bank needs to satisfy before full approval
- That you’re a serious, creditworthy buyer (important when competing with others)
Pre-approval is particularly critical if you plan to bid at auction — auctions are unconditional, so you need to be confident about your finance before bidding.
Pre-approval typically takes 2–7 business days and lasts 90 days. See Mortgage Pre-Approval NZ for the complete guide.
Stage 3: Find a Property and Do Your Research
Working with real estate agents
Real estate agents in NZ are legally required to act in the vendor’s (seller’s) interest, not yours. Their job is to get the best price for the seller. This doesn’t mean they’ll mislead you — but it means you should do your own research and not rely solely on the agent’s assessment of value or condition.
Using TradeMe Property and realestate.co.nz
The two main property listing platforms in NZ are TradeMe Property and realestate.co.nz. Both show asking prices, days on market, and recent sale history (via paid services or free REINZ data).
Understanding asking prices vs market value
In NZ, properties are listed with:
- Asking price — the vendor’s stated price
- Price by negotiation (PBN) — no stated price; you make an offer
- Auction — sold to the highest bidder above reserve
- Tender — sealed bids; vendor chooses the preferred offer
Be cautious about overpaying relative to comparable sales. Check recent sale prices for similar properties in the area using CoreLogic, Homes.co.nz, or your lawyer.
Stage 4: Due Diligence — Research Before You Commit
Never sign a sale and purchase agreement without doing proper due diligence — ideally, start this before making an offer. At minimum, investigate:
LIM Report (Land Information Memorandum)
A LIM report is a council document that tells you everything the council knows about the property:
- Consents for buildings and structures (is the deck or sleepout consented?)
- Drainage plans
- Hazards (flood zones, erosion risk, potential contamination)
- Rates information
Cost: $200–$350. Timeframe: 5–10 working days from council.
Why it matters: If a property has unconsented work, you inherit the liability. Banks may also decline to lend on properties with significant unconsented structures. See LIM Report NZ Guide.
Building Inspection
A licensed building inspector physically inspects the property and produces a written report covering:
- Structural condition
- Roof and weathertightness
- Moisture and dampness (including weather-tightness risk in leaky homes era)
- Plumbing, electrical (visual inspection only), drainage
- Hazardous materials (asbestos, reinforcing — particularly important for pre-1990 homes)
Cost: $400–$700. Timeframe: 2–5 days.
Never skip this. A property that looks fine to the untrained eye may have serious issues. See Building Inspection NZ Guide.
Title Search
Your lawyer will search the property’s certificate of title to confirm:
- Who owns it (matches the vendor)
- No encumbrances (mortgages, covenants, easements) that would affect your ownership or use
- The correct title type (freehold, leasehold, cross lease, unit title)
Cross lease and unit title properties have specific considerations — see Cross Lease NZ and Unit Title NZ.
Earthquake Prone Building Status
In Wellington and Christchurch particularly, check whether the property (especially apartments or unreinforced masonry buildings) is on the earthquake-prone building register. This affects insurability and future remediation costs.
Stage 5: Make an Offer — The Sale and Purchase Agreement
The Sale and Purchase Agreement (S&P) is the legally binding contract between you and the vendor. In NZ, REINZ/ADLS standard form agreements are commonly used.
Key terms to negotiate
- Purchase price — your offer
- Conditions — standard ones include: finance, building inspection, LIM report, valuation
- Condition timeframes — typically 5–15 working days per condition
- Settlement date — when you take possession (typically 1–8 weeks after going unconditional)
- Deposit amount — typically 10% of the purchase price, held in the agent’s trust account until settlement
- Chattels — what’s included (dishwasher, curtains, light fittings — specify what you expect)
Conditional vs unconditional offers
A conditional offer has one or more conditions that must be satisfied. If you can’t satisfy them (e.g., finance is declined), you can cancel the agreement and get your deposit back.
An unconditional offer has no conditions. You are legally bound to complete the purchase regardless. Never go unconditional before you have full mortgage approval and acceptable due diligence results.
At auction, the winning bid is unconditional by definition. This is why pre-approval and pre-auction due diligence are essential. See Property Auction NZ Guide.
Stage 6: Satisfy Your Conditions (Going Unconditional)
Once your offer is accepted, you have the agreed time to satisfy each condition:
Finance condition
Submit your formal mortgage application immediately. Provide your bank or broker with:
- The signed sale and purchase agreement
- Property address and details
- Final financial documents if anything has changed since pre-approval
The bank will arrange a property valuation. If valuation confirms the purchase price is at or near market value, full approval typically follows.
Risk: If the bank’s valuation is lower than the purchase price, you may need to bridge the gap from your own funds. Discuss this with your broker before it happens.
Building inspection condition
If the report identifies significant issues, you can:
- Accept and proceed (if minor issues)
- Negotiate a reduction in purchase price
- Ask the vendor to rectify the issues before settlement
- Cancel the agreement (if serious defects)
LIM condition
If the LIM reveals significant problems (major unconsented works, hazards), discuss with your lawyer before deciding.
Going unconditional
Once all conditions are satisfied, you notify the vendor (via your lawyer or agent) that the agreement is now unconditional. From this moment, you are legally obligated to purchase the property on the agreed terms.
Stage 7: Settlement Preparation
After going unconditional:
Arrange home insurance — many banks require proof of insurance before advancing funds. Insure from the date of going unconditional (not settlement), as you have an insurable interest.
Confirm KiwiSaver withdrawal — if using KiwiSaver, the withdrawal should be underway. Your provider sends funds to your lawyer’s trust account.
Pre-settlement inspection — you’re typically entitled to a pre-settlement inspection 1–2 days before settlement. Check that the property is in the agreed condition and chattels are present.
Final documents — sign mortgage documents with your lawyer. Check interest rates, loan structure, and repayment amounts before signing.
Stage 8: Settlement Day
On settlement day:
- Your lawyer transfers funds to the vendor’s lawyer
- The vendor’s lawyer confirms receipt and hands over the title
- Your bank registers the new mortgage on the title
- Keys are released to you (typically via the real estate agent)
From this moment, the property is yours.
What can delay settlement:
- Your funds arriving late (e.g., KiwiSaver delay)
- Vendor not vacating on time
- Title issues discovered at the last moment
Your lawyer manages most of this — stay in close contact in the days leading up to settlement.
Costs Beyond the Purchase Price
Budget for the following upfront costs on top of your deposit:
| Cost | Approximate amount |
|---|---|
| Legal fees (your lawyer) | $1,500–$2,500 |
| Building inspection | $400–$700 |
| LIM report | $200–$350 |
| Property valuation | $0–$900 (often covered by lender) |
| Mortgage establishment fee | $0–$500 (often waived) |
| Home insurance (first year) | $1,500–$3,000 |
| Moving costs | $500–$3,000 |
| Total upfront costs (beyond deposit) | $5,000–$10,000 |
