Refinance or refix? What's the difference for Kiwi homeowners

If your fixed home loan rate is ending soon, you will hear two words that sound similar but mean different things: refix and refinance. Mixing them up is easy. Getting them clear helps you ask better questions before you talk to anyone.

This guide explains both in plain English, when each conversation usually comes up, and the costs people forget. If you want a rough net after break fees, try the refix vs refinance savings calculator. Estimates only. Still deciding whether a refinance chat makes sense at all? Use the can I refinance checklist. If you want a licensed adviser to compare options for your situation, you can refinance your home loan through Online Home Loans. We match you with an adviser. We do not give advice ourselves.

Refix in plain English

A refix is when you stay with your current bank and choose a new rate (and often a new fixed term) once your current fixed term ends.

In most cases there is no full new loan application, no solicitor discharge and register cycle, and little or no switching cost. Many banks let you lock a new term in the weeks before expiry. Some bank apps open a rate-lock window in that lead-up period. Check what yours offers.

You still choose term length, and sometimes a floating or variable portion. Some people also revisit weekly or fortnightly repayments at the same time (see the repayment frequency calculator; estimates only). The first offer on the screen is not always the sharpest. Online Home Loans does not negotiate for you. A licensed adviser might help you think through that conversation if you engage one.

Doing nothing can leave the loan on the lender's floating or variable rate when the fix ends. ANZ, ASB, Westpac, and Kiwibank each say that for their own products. Check your contract. This page does not say that rate is higher or lower than a fixed special.

Refinance in plain English

A refinance usually means replacing your existing home loan with a new one. Often that is with a different lender. Sometimes people use the word more loosely for a restructure with the same bank. In everyday Kiwi talk, refinance often points to a move.

The new lender reassesses income, expenses, credit, and usually the property. A solicitor or conveyancer discharges the old mortgage and registers the new one with LINZ. That legal step is one reason refinance takes more work than a simple refix.

A move may include a cash contribution (cashback) from the new lender. Cashback usually comes with clawback if you leave early, so it is not free money. See cashback and clawback explained. Refinancing can also be used for rate, structure, equity access, or debt tidy-up, subject to lender criteria. When you borrow more, it is assessed as new lending, not a like-for-like balance move.

For a fuller look at that path, see our refinance overview.

When people look at refixing only

Refixing can be enough when:

• You are generally happy with the bank and the rate looks competitive after a chat.
• You do not want legal work or a full application right now.
• Your situation is simple. No big equity draw, no consolidation, no major structure change.
• You might sell or change plans soon, so switching costs might not pay back.
• You still have clawback on a recent cashback, which can make moving messy.

None of that means refix is "right" for you. It means those are common reasons people stay put at expiry and choose a new term with the same lender.

When a full refinance conversation comes up

People often look harder at a full refinance when:

• There is a meaningful rate or feature gap the current bank will not match.
• They want structure the current bank does not offer well (offset, revolving credit, useful splits).
• They are planning to access equity or consolidate debt. That is new lending, not like-for-like.
• Service or product fit has broken down.
• The fixed term is ending, which is often the cleanest timing because leaving early can trigger a break fee.

Mid-term switches need a break-fee quote first. Fixed expiry removes that particular cost of leaving early, though other costs can still apply.

If your main goal is a lower home loan rate, start there and work out whether stay-and-refix or switch-and-refinance is even worth comparing.

Costs people forget

Headline rate is only part of the picture. Net the expected benefit against the friction you will actually face.

Legal and conveyancing. Discharge of the old mortgage and registration of the new one.

Valuation. The new lender may require one. Sometimes it is waived or automated. Sometimes it is not.

Discharge and documentation fees. Ask for a full cost list, not only the rate.

Break fee. If you leave a fixed term early, ask your current bank for a quote. 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. Quotes can move with wholesale rates, so treat them as time-sensitive.

Cashback clawback. You may still owe clawback on cashback you already received. Any new cashback will have its own clawback terms. Count both.

Then ask a simple question: over the period you actually expect to stay, does the net benefit still look worthwhile after those costs? That is a numbers conversation for you and, if you want one, a licensed adviser.

FAQ

Is refixing the same as refinancing in NZ?

No. Refixing usually means choosing a new rate with your current bank when a fixed term ends. Refinancing usually means replacing the loan, often by moving to a different lender, with a new application and legal work.

Do I pay a break fee if I refix at the end of my term?

Generally no break fee applies simply because a fixed term ends and you choose a new term with the same bank. Break fees are about leaving a fixed contract early. Confirm with your lender.

Can I refinance without changing banks?

People sometimes use "refinance" loosely for restructuring with the same bank. In Kiwi usage, refinance often means a new loan or a different lender. If you stay put and only change the rate at expiry, that is usually called a refix. An adviser can explain which path fits your goal.

How far ahead of my fixed expiry should I start looking?

There is no single official lead time. Check how early your own bank lets you lock a rate. On 5 October 2026, ANZ and Westpac said up to 60 days before expiry, ASB said from 35 days, and Kiwibank said up to 30 days. Those are each bank's own process, and they can change.
