Car Loan Refinancing NZ: How to Refinance Your Car Loan

Car loan refinancing is the process of replacing existing vehicle finance with a new credit agreement. The new finance is used to settle the old loan, after which you make repayments under the terms of the replacement loan.

The first step is finding out exactly how much is required to repay your existing car finance. You can then compare that amount with the replacement finance available. If refinancing proceeds, the existing loan is settled and any security associated with the old finance needs to be dealt with as part of the process.

There are several reasons someone might investigate refinancing. The important question is whether the replacement loan produces a worthwhile improvement after all costs are considered.

The balance shown on an account is not always the same as the amount required to close the loan on a particular date. Ask your existing lender for a current settlement figure before comparing refinancing. This gives you a more accurate starting point for determining how much replacement finance is required.

Future scheduled repayments can include interest that has not yet accrued, while the settlement calculation can include amounts payable when the loan is closed early. The lender can provide the amount required for a particular settlement date.

Potentially. Interest rates and borrower circumstances can change after a vehicle loan is established. Replacement finance may be available at a different rate, but the actual rate depends on the lender and application rather than simply what is advertised.

The benefit of a lower rate depends on the balance still owing and how long the debt would otherwise remain. A rate difference can matter more when a substantial balance and several years of repayments remain.

The example below shows the information you would want before making a decision. The figures are illustrative rather than current finance offers.

A lower new rate can look attractive until the costs of moving the finance are included. Existing finance can have reasonable early-repayment costs, while the replacement loan may have establishment or other fees.

Car finance is often secured against the vehicle. When secured finance is refinanced, the existing lender's security interest needs to be dealt with when the original debt is settled. If the replacement loan is also secured against the car, the new lender may register its own security interest.

The vehicle can be important to a refinancing assessment when it is being used as security. A lender may consider its current value, age, condition and other characteristics alongside the amount you want to refinance.

Negative equity occurs when the amount required to settle the finance is greater than the current value of the vehicle. For example, if the settlement figure is $30,000 but the car is worth approximately $24,000, there is a $6,000 difference.

It can be more difficult because the debt exceeds the value of the vehicle being used as security. Whether refinancing is possible depends on the lender, the amount of negative equity, the proposed finance and the borrower's circumstances.

If the vehicle is worth more than the amount required to settle the loan, you have positive equity in the vehicle. That does not guarantee refinancing approval or a particular rate, but the relationship between the debt and the security can be relevant to the lender's assessment.

Yes, depending on the replacement rate, amount and term. However, a lower repayment can be created simply by extending the debt over more years. That can make the loan easier to manage week to week while potentially increasing the total amount of interest paid.

These are different goals. Someone refinancing primarily to improve cash flow may prioritise the repayment amount, while someone trying to reduce borrowing costs may focus more heavily on the rate, fees and repayment period.

Extending the term can reduce the required repayment, but it also keeps the debt in place for longer. Consider the age of the vehicle and whether you are comfortable still making repayments later in the car's life.

Yes. Cars depreciate and can require more maintenance as they age. A long refinance term can mean paying finance while also facing increasing servicing or repair costs. The repayment should therefore be considered alongside how long you expect to keep the vehicle.

Yes. Refinancing is a new credit application. A lender can assess your credit history, income, expenses, existing financial commitments and other circumstances when determining whether replacement finance is available.

If your financial circumstances or credit profile have changed since you originally financed the vehicle, the options available now may be different. This does not guarantee approval or a lower rate, but it can be a reason to compare current finance.

Potentially. Refinancing does not necessarily require moving to another finance provider. Your existing lender may have options available, while another lender may offer a different structure. Compare the actual costs rather than assuming switching providers is automatically better.

Car refinancing generally focuses on replacing the finance attached to one vehicle. Debt consolidation usually involves combining multiple eligible debts into one new loan. In some circumstances a borrower may be considering both, but they are different financial decisions.

Refinancing can be worth investigating when enough of the existing loan remains for a meaningful difference in rate or structure to matter.

Refinancing may offer limited benefit when the existing loan is almost repaid, the balance is small, settlement and establishment costs are high or the replacement finance substantially extends the term without enough benefit elsewhere.

Use a side-by-side comparison rather than looking at one attractive number.

Before replacing your existing vehicle finance, make sure you can answer the key questions below.

Whether refinancing improves an existing car loan depends on the settlement amount, vehicle, rate, fees, term and finance available to the borrower.
