The NZ mortgage process from first enquiry to unconditional approval and settlement involves multiple stages, each with its own timeline. Understanding the realistic timeframes — and what causes delays — helps you plan your property search and avoid missed deadlines.
Pre-approval takes 3–10 working days. Formal (unconditional) approval after you've found a property takes 3–5 working days if your pre-approval is current and the property is straightforward. Total time from first enquiry to settlement is typically 6–10 weeks. Auctions require funding pre-approved before the auction date.

| Pre-approval decision | 3–10 working days |
| Property search (your timeline) | Weeks to months |
| Offer accepted / contract signed | — |
| Formal approval (unconditional) | 3–5 working days |
| Valuation (if required) | 2–5 additional working days |
| Solicitor settlement process | 5–15 working days |
| Settlement (key handover) | Typically 30–60 days from offer |
Stage 1: Pre-Approval (3–10 Working Days)
Pre-approval (sometimes called conditional approval or approval in principle) is an assessment of your borrowing capacity before you find a specific property.
What lenders assess:
- Income verification (payslips, employment letter, tax returns if self-employed)
- Credit check (Centrix, Equifax, or similar)
- Existing debts and liabilities
- Living expenses (bank statements — typically 3 months)
- KiwiSaver balance and first home withdrawal eligibility
Why it takes longer:
- Incomplete documents (most common cause)
- Complex income (self-employed, multiple sources, irregular)
- Credit issues requiring manual review
- High application volumes at the bank
- Public holidays or staff leave
Using a broker: A broker can often get a faster turnaround by submitting a well-packaged application directly to the bank’s specialist team rather than going through the retail channel.
How long pre-approval lasts: Most NZ bank pre-approvals are valid for 90 days. Some offer 120 days. After expiry, you typically need to reconfirm your financials (updated payslips, bank statements) and the bank re-assesses.
Stage 2: Property Search
This is entirely your timeline — weeks to months depending on market conditions, your requirements, and competition. Your pre-approval is the green light to make offers or bid at auction.
Important: For auctions, you must have pre-approval (ideally formal approval on the property after due diligence) before auction day. Buying at auction is unconditional — you cannot add a finance condition.
Stage 3: Formal (Unconditional) Approval (3–5 Working Days)
Once your offer is accepted and you have a signed sale and purchase agreement, you submit this to your bank to convert your pre-approval to a formal approval. At this stage:
- The bank reviews the specific property (LVR on the actual purchase price)
- A registered valuation may be ordered (adds 2–5 days)
- The bank confirms the loan structure (amount, rate, split)
- You sign the mortgage offer documents
When a valuation is required:
- LVR is above 80% (banks typically require a registered valuation)
- Property type is non-standard (apartment, lifestyle block, leasehold)
- Purchase price seems inconsistent with recent market values
- Bank policy requires it for properties above a threshold value
Valuation costs: $600–$900, paid by the borrower.
Stage 4: Legal Settlement (10–30 Working Days)
After formal approval, your solicitor and the vendor’s solicitor complete the legal transfer. This involves:
- Title search and registration preparation (Land Transfer Act 2017)
- KiwiSaver withdrawal processing (allow 3–5 working days for the provider to release funds)
- Discharge of any existing mortgage on the vendor’s title
- Bank draws down the loan funds on settlement day
- Keys handed over
Typical settlement periods in NZ sale and purchase agreements:
- Standard: 20–30 working days from unconditional date
- Quick: 10 working days (requires all parties to move fast)
- Extended: 40–60 working days (sometimes agreed for new builds or complex situations)
Timeline by Lender Type (2026)

| ASB | 4–7 working days | 2–4 working days |
| BNZ | 5–8 working days | 3–5 working days |
| Westpac | 5–7 working days | 3–5 working days |
| Kiwibank | 7–10 working days | 4–6 working days |
| Non-bank lenders | 2–5 working days | 2–3 working days |
| Mortgage broker (multiple) | 3–7 working days | 2–4 working days |
Indicative only — actual times vary by application complexity and volumes.
What Causes Delays?
Most common causes:
- Missing or incomplete documents — the single most preventable delay. Have everything ready before you apply.
- Registered valuation required — adds 3–7 working days.
- Self-employed income complexity — requires 2 years of financial statements, IR3 returns, often a tax agent letter.
- Credit issues — adverse credit history requires manual underwriting review.
- High bank volumes — pre-approval queues extend during busy periods (spring market, post-OCR rate cuts).
- Solicitor delays — settlement can be delayed if either party’s solicitor is slow.
How to Speed Up the Process
-
Have your documents ready before applying: Payslips (last 3 months), bank statements (3 months), employment confirmation letter, IRD number, photo ID, credit card limits, existing loan statements.
-
Apply with a broker: Brokers know exactly what each bank needs and can submit a clean application with all required documents in one go.
-
Get pre-approval before you find a property: Don’t wait until you’ve found something you love — pre-approval first means you can move immediately.
-
Instruct your solicitor early: Engage a conveyancing solicitor before you start making offers so they’re ready to act immediately.
-
Request KiwiSaver withdrawal early: Once your offer is unconditional, initiate your KiwiSaver first home withdrawal immediately — providers need 3–5 working days minimum.
Frequently Asked Questions
How long does a mortgage pre-approval take in NZ?
Typically 3–10 working days from when you submit a complete application with all documents. Applications with complex income or credit issues take longer. Missing documents are the most common cause of delays.
Can I buy at auction with pre-approval only?
Pre-approval is usually sufficient to bid at auction, but you should have done your due diligence on the specific property. Bidding at auction is unconditional — there is no finance condition. Make sure your pre-approval has been confirmed for that property type and price range.
How long after pre-approval until I need to settle?
Pre-approval is valid for 90 days (sometimes 120). Settlement typically occurs 30–60 days after your offer is accepted (unconditional). The full cycle from pre-approval to settlement is typically 4–10 weeks once you find a property.
Can I get a mortgage approved in a week in NZ?
In exceptional cases, yes — particularly with a broker, a clean application, no valuation required, and a responsive bank. But plan for 3–5 working days as the minimum, and more commonly 7–10 working days for pre-approval.
Do I need a solicitor before mortgage approval?
No — but you must instruct a solicitor once you have a signed sale and purchase agreement. Most buyers engage a solicitor (conveyancer) during their property search so they’re ready to review the S&P agreement quickly.
