Refix vs Refinance vs Restructure: What’s the Difference in NZ?

What Does Refixing a Mortgage Mean?

Refixing normally happens when your current fixed-rate period is approaching its expiry date.

For example, suppose you originally fixed your mortgage for two years.

At the end of those two years, your lender may offer you several new options such as:

• Six months fixed
• One year fixed
• Two years fixed
• Three years fixed
• A floating rate
• A combination of fixed and floating lending

Selecting another fixed term with the same lender is generally referred to as refixing your mortgage.

If your fixed term is approaching expiry, explore our Refix Mortgage Services before accepting a new rate automatically.

What Happens When Your Fixed Mortgage Term Ends?

When a fixed term expires, you normally need to decide whether to:

• Refix for another period
• Move onto a floating rate
• Split the mortgage
• Restructure the loan
• Refinance to another lender

The exact process differs between banks.

For example, BNZ states that an eligible loan may automatically move to its standard variable rate after the fixed term ends if the borrower does not refix. Other lenders have their own processes and terms.

This is why the end of a fixed term can be a useful mortgage review point rather than simply an administrative renewal.

When Might Refixing Be Suitable?

Refixing may be worth considering when:

• You are satisfied with your current bank
• Your existing mortgage structure still suits you
• Your fixed term is ending
• Your lender is offering competitive terms
• You do not want the cost or administration of changing lenders
• Your borrowing needs have not materially changed
• You do not need additional lending
• You want repayment certainty for another fixed period

However, remaining with your current bank should still be an active decision rather than an automatic one.

Before refixing, compare:

• Available fixed terms
• Floating options
• Repayment flexibility
• Your future plans
• Competing lender options
• The possibility of restructuring

Our Refix Mortgage Services can help you review these considerations before the existing fixed term expires.

What Does Refinancing a Mortgage Mean?

Mortgage refinancing generally means replacing your existing mortgage with a new mortgage arrangement.

In New Zealand, this commonly involves moving your home loan from one bank or lender to another.

For example:

You currently owe $650,000 to Bank A.

After reviewing your options, Bank B approves a new $650,000 home loan.

The new lending is used to repay Bank A, and your mortgage moves to Bank B.

This is mortgage refinancing.

For personalised help comparing lenders, see our Refinance Mortgage Services.

Why Do People Refinance Their Mortgage?

A lower interest rate is one reason, but it is not the only reason homeowners consider refinancing.

You might refinance because you want to:

Get a more competitive mortgage rate

A lower rate can potentially reduce repayments or total interest costs.

But always calculate the saving after refinancing costs.

Improve your loan structure

Your current mortgage may no longer fit your income, savings or financial goals.

A new lender may provide a structure that better suits your needs.

Access better mortgage features

These might include:

• Offset accounts
• Revolving credit
• Greater extra-repayment flexibility
• Different fixed-term options
• More suitable split-loan structures

Access property equity

If your property has increased in value or your mortgage balance has reduced, you may have equity that could potentially support additional borrowing.

Depending on lender approval and affordability, equity might be used for:

• An investment-property deposit
• Renovations
• Another property purchase
• Other approved purposes

Read more about Equity Release Services.

Buy an investment property

Homeowners sometimes refinance as part of a wider property-investment strategy.

This may involve reviewing:

• Available equity
• Existing mortgage structure
• Deposit requirements
• Rental income
• Servicing
• Future portfolio plans

Learn more through our Investment Property Loans.

Fund a renovation

Refinancing or increasing mortgage lending may be one way to fund significant home improvements.

Depending on the project, other options may include a mortgage top-up or dedicated renovation lending.

See our Home Renovation Loans or read our guide to using equity for home renovation.

Fund a new build

Larger construction projects can require a different lending structure involving staged progress payments.

If your plans involve building rather than simply renovating, see our Building Construction Loans.

What Does Restructuring a Mortgage Mean?

Mortgage restructuring means changing the way your home loan is organised.

You may remain with the same bank.

For example, instead of having one $600,000 mortgage fixed for two years, you might restructure it into:

• $300,000 fixed for one year
• $200,000 fixed for two years
• $100,000 floating or offset

That is a different mortgage structure even though:

• Your total debt may remain $600,000
• You may remain with the same bank
• You may still own the same property

Explore our Mortgage Loan Restructure Services if your current loan setup no longer suits your financial plans.

Why Would You Restructure Your Mortgage?

Mortgage restructuring may be considered when you want to improve:

• Repayment flexibility
• Cash-flow management
• Interest-rate exposure
• Ability to make additional repayments
• Use of savings
• Debt repayment strategy
• Financial resilience

Your circumstances may also have changed since the mortgage was originally arranged.

For example:

• Your income has increased
• One partner has stopped working
• You have had children
• You have built more savings
• You received an inheritance
• You are planning an investment purchase
• You want to renovate
• You want to repay the mortgage faster
• Your existing repayments are becoming difficult

The structure that suited you five years ago may not necessarily suit you today.

Common Ways to Restructure a Mortgage

Split the mortgage

Instead of fixing the entire loan for one term, you may divide it into several portions.

For example:

• Part fixed for one year
• Part fixed for two years
• Part floating

The objective is usually to balance certainty with flexibility.

Add a floating portion

Floating lending may provide more flexibility for additional repayments.

However, floating interest rates can change and may be higher than available fixed rates.

Use an offset mortgage

Some lenders offer offset products that allow eligible savings balances to reduce the portion of the mortgage on which interest is calculated.

The availability and mechanics depend on the lender.

Use revolving credit

Revolving credit operates differently from a conventional fixed-term mortgage and requires financial discipline.

It may suit some borrowers with strong cash-flow management but may be unsuitable for others.

Change the repayment term

Extending a loan term can reduce regular repayments but may increase the total amount of interest paid over time.

Shortening the term generally increases repayments but can reduce long-term interest costs.

Increase repayments

Borrowers whose income has increased may consider increasing repayments to reduce principal faster.

Always check applicable lender limits and fixed-rate conditions first.

Refix vs Refinance: What Is the Difference?

This is one of the most common sources of confusion.

Refix

You normally:

• Stay with your current lender
• Select another interest-rate term
• Keep substantially the same mortgage relationship
• Avoid a complete lender-switch process

Refinance

You may:

• Move to another lender
• Complete a fresh lending assessment
• Provide updated financial documents
• Change loan products
• Change mortgage structure
• Potentially incur legal or valuation costs

So if your existing bank simply offers you a new one-year fixed rate when your previous fixed term ends, that is generally refixing, not refinancing.

For help deciding whether remaining with your current lender makes sense, compare our Refix Mortgage Services with our Refinance Mortgage Services.

Refinance vs Restructure: What Is the Difference?

Refinancing and restructuring can overlap, but they are not the same.

Mortgage refinance

Focuses primarily on replacing or changing the lending arrangement, often involving another lender.

Mortgage restructure

Focuses on changing how the existing debt is organised.

You may refinance and restructure at the same time.

For example:

You move a $700,000 mortgage from Bank A to Bank B.

At Bank A it was entirely fixed.

At Bank B you create:

• $300,000 fixed
• $250,000 fixed for a different term
• $150,000 offset

You have both:

Refinanced the mortgage
and Restructured the mortgage.

Do You Need to Refinance to Restructure?

No.

In many cases, your current bank may allow you to change the structure without moving the entire loan to another lender.

Whether this can be done immediately depends on:

• Existing fixed terms
• Break costs
• Loan products
• Lender rules
• Whether additional borrowing is needed
• Affordability
• Your overall financial position

That is why restructuring should normally begin with a review of the existing mortgage rather than immediately applying to another bank.

See Mortgage Loan Restructure Services for more information.

How Much Does It Cost to Refinance a Mortgage in NZ?

This is extremely important.

A new lender might offer a lower rate, but switching may still cost more than staying where you are.

Possible refinancing costs include:

• Legal fees
• Property-valuation fees
• Early-repayment charges
• Fixed-rate break fees
• Cashback repayment
• Mortgage-adviser fees in applicable circumstances
• Commission-clawback-related adviser fees
• New lender fees

BNZ specifically identifies legal costs, early repayment fees, cashback clawbacks and valuation costs as potential refinancing expenses.

Consumer Protection also explains that a break or early-repayment fee may apply when a fixed-term loan is repaid early, including when switching mortgage deals before the fixed period ends.

What Is a Mortgage Break Fee?

A mortgage break fee may apply when you repay or change a fixed-rate loan before the agreed fixed term ends.

This could occur when:

• You refinance
• You sell your property
• You repay the mortgage early
• You try to move to another fixed rate early

Consumer Protection explains that early repayment charges can include administrative costs and a reasonable estimate of losses caused by changes in market interest rates.

Before refinancing a fixed mortgage, ask your lender for a current break-cost calculation.

What About Bank Cashback?

Some lenders offer cash incentives to borrowers who take out or refinance a mortgage.

Cashback can be attractive, but it should not be the main reason for choosing a lender.

Check:

• How long you must remain with the lender
• Whether cashback must be repaid if you leave early
• Whether the new mortgage rate is competitive
• Loan flexibility
• Legal costs
• Any adviser clawback-related fee
• Total benefit after all switching costs

The Financial Markets Authority advises borrowers to be careful about short-term incentives such as cashback and to consider the long-term fundamentals of the mortgage.

Is Refinancing Worth It for a Small Interest-Rate Difference?

Not necessarily.

Imagine:

Current mortgage: $600,000
Current rate: 6.00%
Alternative rate: 5.80%

The new rate is 0.20 percentage points lower.

That looks attractive.

But suppose changing lenders involves:

• Legal costs
• Valuation
• Existing-bank cashback repayment
• Break fees

The immediate cost of switching could offset a meaningful portion of the interest saving.

Instead of asking:

“Is this new rate lower?”

Ask:

“After all costs, how much better off will I actually be?”

This is the core calculation behind a sensible refinance mortgage strategy.

When Might Refinancing Make Sense?

Refinancing may deserve consideration when:

• Another lender offers materially better terms
• Your existing bank is not competitive
• Your fixed term is approaching expiry
• You want different loan features
• Your financial circumstances have changed
• You want to access equity
• You are buying another property
• You want to combine lending
• Your existing structure is unsuitable
• You need a lender with different credit or income policies

You can review available options through our Refinance Mortgage Services.

When Might Refixing Make More Sense?

Refixing may be simpler when:

• Your existing lender remains competitive
• You are happy with the bank
• Your current loan structure works
• There is little financial benefit in switching
• Refinancing costs outweigh the potential saving
• You do not require additional lending

When Might Restructuring Be More Useful?

Restructuring may be worth reviewing when:

• Your repayments are uncomfortable
• You have excess cash sitting separately from the mortgage
• You want to repay the loan faster
• You need greater flexibility
• You want to split interest-rate risk
• Your household income has changed
• You are preparing to invest
• You are planning renovations
• You have several debts or mortgage portions
• Your current mortgage was structured years ago

See our Mortgage Loan Restructure Services.

Can You Refinance to Release Equity?

Potentially.

If your property has increased in value or you have paid down your mortgage, there may be equity available.

However:

Property equity does not automatically equal borrowing capacity.

The lender may still assess:

• Income
• Expenses
• Existing debts
• LVR
• DTI
• Credit history
• Loan purpose
• Property
• Overall affordability

Equity might potentially be used for:

• Investment property
• Renovations
• Supporting another property purchase
• Other approved purposes

Can You Refinance to Buy an Investment Property?

Refinancing may form part of an investment-purchase strategy.

For example, an existing homeowner might refinance or restructure part of their mortgage to access usable equity for an investment-property deposit.

The lender will still assess:

• Total debt
• Income
• Rental income
• Deposit
• LVR
• DTI
• Existing mortgage commitments
• Property type
• Affordability

Property investors can explore our Investment Property Loans and Residential Investment Home Loans.

Can You Refinance to Renovate Your Home?

Potentially.

Depending on the size of the project and available equity, homeowners may consider:

• Mortgage top-up
• Equity release
• Refinancing
• Renovation loan
• Construction loan

For smaller to medium projects, see Home Renovation Loans.

For major structural work or new builds, see Building Construction Loans.

Can You Refinance a First Home Loan?

Existing first-home buyers may later refinance just like other homeowners, subject to lender approval.

You might review your loan after:

• Building more equity
• Increasing your income
• Reaching the end of a fixed term
• Wanting different loan features
• Changing property plans

If you are still preparing to purchase your first property rather than refinancing an existing mortgage, see our First Home Loans in New Zealand.

Should You Refinance After Your Bank Declines Additional Lending?

Not automatically.

If your current bank declines:

• A mortgage top-up
• Equity release
• An investment purchase
• Additional borrowing

the first step should be understanding why.

Another bank may assess the application differently, but a different lender cannot remove a genuine affordability problem.

Can a Mortgage Broker Help With Refixing, Refinancing and Restructuring?

Yes.

A mortgage adviser may help you compare all three options rather than starting with the assumption that you should switch banks.

A mortgage adviser can review:

• Existing mortgage balance
• Interest rates
• Fixed-term expiry dates
• Loan portions
• Repayments
• Break costs
• Equity
• Income
• Expenses
• Other debts
• Future property plans
• Available lender options

The Financial Markets Authority states that mortgage advisers can help borrowers understand needs and budgets, assess options, explain loan costs and manage the lending process.

Frequently Asked Questions

What is the difference between refixing and refinancing a mortgage?

Refixing normally means selecting another fixed interest-rate period while remaining with your current lender. Refinancing generally involves replacing your existing mortgage and often moving to another lender.

Is refinancing the same as restructuring?

No. Refinancing changes the lending arrangement, while restructuring changes how the mortgage is organised. You can refinance and restructure at the same time.

Do I have to change banks to refix my mortgage?

No. Refixing normally happens with your existing lender.

Do I have to change banks to restructure my mortgage?

Not necessarily. Your current lender may allow changes to your mortgage structure.

When should I start reviewing my refix options?

Start reviewing the mortgage before the fixed term expires rather than waiting until the last day. The exact early-refix or rate-lock window differs between lenders.

Does refinancing always save money?

No. A lower interest rate does not guarantee an overall saving once legal fees, valuation costs, break fees, cashback repayments and other costs are included.

Can I refinance while my mortgage is fixed?

Potentially, but an early-repayment or break charge may apply. Ask your existing lender for the cost before proceeding.

Can I refinance to access equity?

Potentially, subject to the lender’s assessment of property value, affordability, LVR, DTI and other lending criteria.

Can I refinance to consolidate debt?

It may be possible, but moving short-term debt into a long-term mortgage can increase the total interest paid if the debt is repaid over a much longer period. The costs and risks should be assessed carefully.

Is it better to refinance or ask my bank for a better rate?

Both options may be worth exploring. Compare your current lender’s offer with the total cost and benefits of switching.

Can a mortgage broker negotiate a refix rate?

Depending on the adviser’s relationship with your lender and its processes, an adviser may help review available options. Ask what lenders and refix services the adviser can provide.

Should I refinance for cashback?

Cashback should be treated as one component of the overall offer rather than the main reason to move. Consider interest, fees, structure, flexibility and any obligation to repay the cashback if you leave early.

Can investment-property mortgages be refinanced?

Yes, subject to lender criteria and affordability. Property investors may refinance to review rates, structures, equity or portfolio lending.

Can I refinance if my financial circumstances have changed?

Possibly. A new lender will normally reassess your financial position and may require updated income, expense, debt and property information.

What documents are required to refinance?

Requirements vary, but borrowers may be asked for identification, income evidence, bank statements, current loan statements, information about debts and supporting property information. One current bank refinancing guide, for example, requires updated income and account evidence before assessment.

Which Option Is Right for You?

There is no universal answer.

Consider refixing when:

• Your fixed term is ending
• Your current lender remains suitable
• Your mortgage structure still works

Consider refinancing when:

• Another lender may offer materially better overall terms
• You want different features
• Your current lender no longer suits your needs
• You are considering accessing equity
• Your financial goals have changed

Consider restructuring when:

• The lender may remain suitable
• The way your loan is structured no longer works
• You want greater repayment flexibility
• You want to manage interest-rate exposure differently
• You want to improve cash-flow management

In some cases, the right answer may involve a combination.

For example:

Restructure now → refix one portion → refinance later if another lender provides a meaningful overall benefit.

The decision should be based on your individual financial position rather than a headline interest rate.

Review Your Mortgage Before Making a Decision

If your fixed term is ending, your repayments have changed or you are considering moving banks, use the opportunity to review the entire mortgage.
