Refinancing Loans NZ: How Does Refinancing Work?

Learn how loan refinancing works in NZ, including replacing an existing loan, rates, fees, repayments and what to compare before refinancing.

New Zealand borrower comparing an existing loan with refinancing options

Refinancing means replacing an existing loan with new finance. Someone might refinance to seek a different interest rate, change their repayment amount, alter the loan term or move their debt to a different lender. A new loan can sometimes improve the cost or structure of existing finance, but refinancing is not automatically cheaper. The rate, fees, settlement costs and new loan term all need to be compared before deciding whether refinancing makes sense.

Key takeaways

  • Refinancing replaces an existing loan with new finance.
  • A lower interest rate can potentially reduce borrowing costs, but fees and the new loan term also matter.
  • A lower repayment does not necessarily mean the refinanced loan costs less overall.
  • You should obtain a settlement figure for the existing loan before comparing refinancing options.
  • Extending the loan term can reduce regular repayments while increasing the time you remain in debt.
  • Compare the total cost of keeping your current loan with the complete cost of replacing it.

What does refinancing a loan mean?

Refinancing involves taking out new finance to repay an existing loan. Once the original debt has been settled, you repay the replacement loan according to its own interest rate, fees, term and repayment schedule.

Quick answer

Refinancing does not remove the debt. It replaces the existing loan with a new credit agreement.

How does loan refinancing work?

The process starts by finding out exactly what is required to settle the existing finance. You can then compare that amount with the new finance available to you. If refinancing is approved and completed, the existing debt is repaid and the replacement loan becomes the debt you repay going forward.

Why do people refinance loans?

There are several reasons someone might consider refinancing. The potential benefit depends on what changes between the existing loan and the replacement finance.

Reason for refinancingWhat the borrower may be trying to change
Seek a lower rateReduce the interest cost of the debt
Change repaymentsCreate a repayment structure that better suits the current budget
Change the loan termRepay the debt faster or spread it across a different period
Change lenderMove the debt to a different finance provider
Change loan structureReplace existing finance with a different type of loan

Can refinancing get you a lower interest rate?

Potentially. Interest rates and lending circumstances can change after a loan is originally taken out. Another lender or finance product may offer a different rate. However, the rate available depends on the application, and an advertised lower rate does not guarantee that you will qualify for it.

Quick answer

Compare the actual refinancing rate offered to you with the rate on your existing loan rather than comparing advertised starting rates.

How much difference can a lower rate make?

The impact depends on the amount still owing and how long the debt will remain. A rate reduction on a small balance with only a short time remaining may have a relatively limited effect, while a difference on a larger balance over several years can be more significant.

Your settlement figure is the starting point

Before comparing refinancing, ask your existing lender for a current settlement figure. This is the amount required to repay the existing loan in full on a specified date. It is more useful than simply adding up your remaining scheduled repayments because those repayments can include future interest that has not yet accrued.

Quick answer

Use a current settlement figure when calculating how much new finance is actually required.

Can there be a cost to settling your existing loan?

Yes. Depending on the credit contract, reasonable early-repayment or administration costs can apply when finance is repaid before its scheduled end. These costs need to be included when deciding whether refinancing produces a genuine saving.

The new loan can have fees too

Refinancing can involve costs on both sides of the transaction. You may face costs associated with settling the existing finance as well as establishment or other fees on the replacement loan.

CostWhere to check

Early-repayment costsExisting credit contract
New establishment feeReplacement finance
Security-related costsReplacement finance if applicable
Ongoing feesNew credit contract
InterestCompare old and new finance

A lower rate does not automatically mean refinancing saves money

Suppose the replacement loan has a lower interest rate but requires a significant establishment fee or extends the debt for several additional years. Those differences can reduce or eliminate the benefit of the lower rate. This is why the complete cost needs to be compared.

What happens to your repayments when you refinance?

Your new repayment depends on the replacement loan amount, rate and term. It may be lower, similar or higher than your existing repayment. A smaller repayment can improve regular cash flow, but you should identify why the payment has fallen.

Quick answer

If the new repayment is lower mainly because the debt has been stretched over a longer period, you may pay for the loan for longer and potentially pay more interest.

Example: lower repayment vs shorter loan

Imagine two refinancing options for the same remaining debt. One extends the loan term to produce a smaller weekly payment, while another keeps the term shorter with a larger repayment. Neither is automatically better based on the repayment alone.

OptionPotential advantagePotential trade-off
Longer refinance termSmaller regular repaymentDebt remains for longer
Shorter refinance termDebt can be cleared soonerLarger regular repayment
Lower-rate refinanceCan reduce interest costFees still need to be considered

Can you refinance a car loan?

Car finance can potentially be refinanced with replacement finance, depending on the lender, vehicle, existing agreement and borrower. If the existing loan is secured against the vehicle, the existing lender's security interest needs to be dealt with as part of settling that finance.

Why might someone refinance a car loan?

A borrower might investigate refinancing because their circumstances have changed, different rates are available, or they want a different repayment structure. The remaining value of the vehicle and the amount still owing can also be relevant to the options available.

Can you refinance a personal loan?

An existing personal loan can potentially be replaced with new finance. As with other refinancing, compare the settlement amount and remaining cost of the existing loan against the rate, fees and term of the proposed replacement loan.

Refinancing one loan vs consolidating several debts

Refinancing and debt consolidation are related but not identical. Refinancing commonly refers to replacing existing finance with a new loan, while debt consolidation specifically involves combining multiple eligible debts into replacement finance.

RefinancingDebt consolidation
Can replace one existing loanUsually combines multiple eligible debts
May change rate, lender or termCreates one new repayment for combined debts
Focuses on replacing existing financeFocuses on combining debt

Can you refinance with the same lender?

Potentially, depending on the lender and products available. Refinancing does not necessarily require moving to a different provider. What matters is how the replacement finance compares with keeping the existing agreement.

Does your credit history matter when refinancing?

Refinancing involves applying for new credit, so lenders can assess your current circumstances rather than simply relying on the fact that you already have a loan. Credit history, income, expenses, existing debts and the proposed refinance amount can all be relevant.

What if your financial position has improved?

If your circumstances have materially changed since taking out the original finance, the lending options available now may differ from those available previously. That does not guarantee a lower rate or approval, but it can be one reason borrowers investigate refinancing.

What if the amount owing is more than the asset is worth?

This can be relevant when refinancing secured finance such as a vehicle loan. If the outstanding settlement amount exceeds the current value of the asset, the borrower has negative equity. That can affect the refinancing options available because the debt exceeds the value of the security.

Should you refinance just to lower your weekly repayment?

Not without checking the total cost. Lowering the repayment can be useful when it genuinely improves affordability, but extending the debt can increase the amount paid overall.

Quick answer

Ask both: 'What will my new repayment be?' and 'How much will I repay altogether?'

When refinancing may be worth investigating

Refinancing can be worth comparing when there is a meaningful potential improvement in the cost or structure of the loan. The key is whether the benefit remains after all costs are included.

SituationWhat to investigate
Rates have changedWhether a meaningfully lower actual rate is available
Your circumstances have changedWhether different finance is now available
Current repayment structure no longer suitsAlternative affordable terms
Existing loan has substantial time remainingPotential interest difference over the remaining period
You want to change lenderComplete cost of moving the finance

When refinancing may make less sense

The potential benefit may be limited when the existing loan is nearly repaid, the settlement costs are high, the new loan has significant fees or the refinance substantially extends the debt without producing enough other benefit.

How to compare refinancing properly

Put the existing loan and proposed replacement finance side by side. Avoid comparing only the interest rates or repayments.

Compare refinancing options

Refinancing can potentially change the rate, repayments, term or lender attached to an existing debt, but whether it improves your position depends on the finance available. EveryLoan refers visitors to Simplify Finance, where applications, lender matching, credit decisions and funding are handled by Simplify Finance and its lender partners.

Quick answer

EveryLoan is not a lender. Refinancing approval, rates, fees and loan terms depend on the lender and your individual application.

FAQ

Frequently asked questions

Refinancing means replacing existing finance with a new loan. The original loan is settled and the borrower then repays the replacement finance.

Potentially. A different rate may be available, but whether refinancing saves money also depends on fees, settlement costs and the new loan term.

Car finance can potentially be refinanced depending on the lender, vehicle, existing loan and borrower circumstances. Any existing security interest also needs to be dealt with.

Potentially. Compare the settlement cost and remaining cost of your existing personal loan with the rate, fees, term and total cost of replacement finance.

Not automatically. Refinancing replaces the existing debt with new finance. It changes the loan rather than simply removing the balance.

It could be because of a lower rate, a longer loan term or both. Check the total amount repayable to understand whether the new loan is actually cheaper.

There can be costs associated with settling existing finance and establishing a new loan. Check both credit contracts when comparing the overall cost.
