How to refinance your home loan in NZ (step by step)

Refinancing a home loan in New Zealand means replacing your current loan with a new one, often with a different lender. It is more paperwork than a simple refix at the same bank, but it is also how many people change rate, structure, or borrowing amount when their situation calls for a fresh look.

This walkthrough covers the process at a high level. It is general information, not personal advice. If you want someone licensed to run the numbers for your file, you can refinance your home loan by sending a short enquiry. Online Home Loans matches you with an adviser. We do not advise, set rates, or approve loans.

What refinancing means in New Zealand

You take out a new home loan that pays out the old one. The new lender assesses you under their criteria. A solicitor or conveyancer handles discharge of the old mortgage and registration of the new one with LINZ.

That is different from a refix, where you usually stay with the same bank and choose a new rate when a fixed term ends. If you are still sorting that distinction, read our guide on refinance vs refix first.

People refinance for different goals: a better rate or features, accessing equity, consolidating other debts (see the debt consolidation calculator for a rough sketch), or fixing a product that no longer fits. Those goals can change how the application is assessed. Borrowing more is new lending. A like-for-like balance move (same or lower loan amount) can sit under different macro-prudential settings, but banks still apply their own criteria either way. An exemption from speed limits is not a guarantee of approval.

Good moments to review

There is no single "must act" date. A review can conclude that staying and refixing is fine. Common triggers include:

• Your fixed term is ending soon.
• The gap between your rate or features and what is available elsewhere looks material after costs. There is no universal threshold that says "always move."
• You have equity or debt goals you want to explore.
• Life has changed: income, family, property plans, or how you use the loan day to day.

If your main aim is simply a lower rate at rollover, start with that lens and decide whether a full refinance conversation is even needed. Unsure whether a chat is worth it yet? Try the can I refinance checklist for a traffic-light style readiness sketch. Educational only. Not approval.

Step 1: Get a clear picture of your current loan

Before anyone can help, gather the basics:

• Current balance and interest rate
• Fixed expiry date and remaining overall term
• Repayment amount and frequency
• Any cashback you received and when clawback ends
• Other debts (secured or unsecured) that sit in the wider picture
• Whether the loan is in your personal name, a trust, or a company

Your latest mortgage statement and relevant loan contract details help an adviser a lot. You do not need a perfect spreadsheet. You need accurate inputs so comparisons are not guesswork.

Step 2: Ask about break costs if you are mid-fix

If you are still inside a fixed term and thinking of leaving early, ask your current bank for a break-fee quote. Figures can change with wholesale rates, so treat the quote as dated and ask how long it remains useful.

Where the loan is a consumer credit contract, section 54 of the Credit Contracts and Consumer Finance Act 2003 says a full-prepayment fee must be calculated as a reasonable estimate of the lender's loss. Not every loan is a consumer credit contract. Ask the lender how your quote was worked out. If the quote is large, many people wait for expiry rather than paying to leave early. That is a personal numbers call. Online Home Loans will not tell you which way to go.

If expiry is close, starting the refinance conversation early still helps, because settlement needs time even when there is no break fee.

Step 3: Compare the whole deal, not just the headline rate

Rate matters. So do cashback and clawback length, fees, product features, and structure (splits, offset, revolving credit, repayment flexibility). If you are comparing weekly, fortnightly, and monthly debits, try the repayment frequency calculator. Estimates only.

Also weigh any retention offer from your current bank against the cost and hassle of moving. Online Home Loans does not compare lenders itself. A licensed adviser can, across the lenders they hold accreditation with.

Net expected benefit over the time you actually expect to stay. Include:

• Legal and conveyancing costs
• Valuation if required
• Discharge and documentation fees
• Break fee if you are mid-fix
• Clawback you might owe on the way out
• Clawback terms on any new cashback

Cashback without clawback in the same conversation is incomplete. Treat both sides together.

Step 4: Approval, valuation, solicitor, settlement

At a high level the path looks like this:

1. Application and documents. Photo ID, income evidence (payslips or accounts), recent bank and mortgage statements, details of other debts, property information. Self-employed applicants usually need more financials. Trust or company borrowing adds entity documents.
2. Credit and serviceability checks. The lender assesses whether the loan fits their policy, often at their own stress-test rate for serviceability.
3. Valuation if required. Some lower-risk cases use automated valuations. Others need a registered valuation. The lender decides.
4. Loan offer. Conditions and pricing set out in writing. Read conditions carefully before you celebrate.
5. Solicitor or conveyancer. Discharge of the old mortgage and registration of the new one on the land title register kept under the Land Transfer Act 2017, which Land Information New Zealand administers. Settlement funds flow so the new lender repays the old loan.
6. Insurance. Ask your insurer whether the mortgagee details on the policy need updating.

None of that is a checklist of guarantees. It is the usual plumbing so you know what "refinance process" means in practice.

How long it often takes

Timelines vary. This page does not state a number of weeks.

Delays often come from incomplete documents, self-employed financials, valuation timing, trusts or company structures, or conditions on the loan offer. Ask the adviser or lender for a timeline that fits your file rather than relying on a blog average.

Where a licensed mortgage adviser helps, and what Online Home Loans does

A licensed mortgage adviser can assess options across lenders they work with, explain trade-offs, and lodge applications where you engage them. They give their own disclosure and advice about how they are paid.

Online Home Loans is the front door. You enquire, we match and refer, then we step back. We do not give financial advice. We do not set rates or approve loans. Online Home Loans is a referral service provided by Summit Wealth Limited, trading as Summit Mortgages.

Before you enquire, you can also run the can I refinance checklist to gather next-check questions. Then, if you are ready to talk it through with a licensed adviser, send an enquiry and we will connect you.

FAQ

How long does a refinance take in NZ?

It varies. This page does not state a number of weeks. Complex income, valuations, or legal issues can take longer than a simple file. Ask the adviser or lender for a timeline for your file.

What documents will I need?

Typically photo ID, proof of income (payslips or accounts), recent bank and mortgage statements, and details of other debts. Self-employed applicants usually need more financials. Your adviser or lender will give a checklist.

Will I need a new valuation?

Sometimes. Some lenders accept automated valuations for lower-risk refinances. Others require a registered valuation. The lender decides.

Does like-for-like refinance get treated differently for LVR?

RBNZ guidance says LVR restrictions do not apply to refinancing where the new loan value does not exceed the original loan value (with related conditions). If you borrow more (top-up, cash-out, consolidation), the extra lending is assessed as new lending. Banks still apply their own criteria either way. An exemption from speed limits is not the same as a guarantee of approval.
