Secured Vs Unsecured Loans

Secured vs Unsecured Personal Loans in NZ

When you apply for a personal loan in New Zealand, one of the first distinctions you will come across is whether the loan is secured or unsecured. This affects the interest rate offered, the documentation required, and the consequences if repayments are not maintained.

This guide explains how each structure works, what lenders look at, and how to compare the two fairly.

What Is the Difference Between a Secured and Unsecured Loan?

The core difference is collateral - an asset the lender holds a registered interest over in case the loan is not repaid.

*Estimated total repayable figures are illustrative. Actual rates and fees vary by lender and individual circumstances.

What Is a Secured Personal Loan?

A secured loan is backed by an asset. In New Zealand personal lending, the collateral is almost always the vehicle being purchased - a car, SUV, ute, motorcycle, caravan, boat, or EV.

When a lender approves a secured loan, they register a security interest over the vehicle on the Personal Property Securities Register (PPSR). This means if the borrower defaults and the debt cannot be resolved, the lender has the legal right to repossess and sell the asset to recover the outstanding balance.

Because the lender has an asset to fall back on, the risk to them is lower - and that reduced risk is typically reflected in a lower interest rate.

What lenders assess for a secured loan

For a secured vehicle loan, lenders assess two things: the borrower and the vehicle.

• Borrower: income, employment type, living expenses, credit history, and existing financial commitments
• Vehicle: registered market value, age, condition, and kilometres

Vehicles that are too old, very high in kilometres, or below a minimum value threshold may not qualify for secured lending. In those cases, the loan would need to be structured as unsecured - which means a higher rate.

What Is an Unsecured Personal Loan?

An unsecured loan has no specific collateral. The lender is relying entirely on the borrower's financial profile - income, expenses, credit history, and account conduct - to assess the risk of lending.

If a borrower defaults on an unsecured loan, the lender's recovery options are through the courts rather than the repossession of an asset. This additional risk is reflected in a higher interest rate compared to secured lending.

Unsecured loans are typically used for purposes that do not involve a physical asset - debt consolidation, home improvements, medical or dental costs, travel, or other personal expenses.

How the Rate Difference Adds Up

The gap between secured and unsecured rates can have a meaningful effect on the total cost of a loan. Here is an example using a $15,000 loan over 60 months:

*Estimates only. Excludes establishment fees and other charges. Actual rates depend on individual circumstances and lender.

On a $15,000 loan, a 5% rate difference over five years produces a gap of over $2,000 in total interest paid. On a larger loan or longer term, the gap widens further. This is why matching the loan type to the purpose matters - using an unsecured loan for something that could be financed on a secured basis costs more.

Secured and Unsecured Loans - Advantages and Considerations

When Is Each Type Used?

Secured loans - typically used for vehicle finance

Because the vehicle provides the collateral, secured lending is the standard structure for car loans, EV loans, motorcycle finance, caravan loans, and boat finance in New Zealand. The lender's registration on the PPSR also protects their interest if the vehicle is sold before the loan is repaid.

Unsecured loans - typically used for personal expenses

When there is no asset involved - debt consolidation, home renovations, medical costs, a holiday, or a life event - an unsecured personal loan is the standard approach. Some lenders will also offer unsecured lending for vehicle purchases where the vehicle does not qualify for secured status.

The CCCFA Applies to Both

Regardless of loan type, all consumer lenders in New Zealand must comply with the Credit Contracts and Consumer Finance Act (CCCFA). This requires lenders to make reasonable enquiries into whether a loan is affordable and suitable for the individual borrower, based on their current income, expenses, and existing commitments.

Security reduces the lender's financial exposure if a loan goes wrong. It does not reduce the lender's legal obligation to assess whether the loan is appropriate in the first place. A secured loan application can still be declined if it does not pass the affordability assessment.

How to Compare Secured and Unsecured Offers

If you are comparing two offers for the same purpose, the clearest comparison is the total amount repayable over the full term - not the weekly or fortnightly repayment. Use the Nomu loan calculator to run both scenarios with the relevant rates, terms, and fees, then compare the total figures.

A secured loan at a lower rate over a longer term may produce a similar weekly repayment to an unsecured loan at a higher rate over a shorter term - but the total repayable will be different, and that is the number that reflects the true cost.

Also factor in fees: establishment fees, any PPSR registration charge on a secured loan, and early repayment fees if you plan to pay the loan out ahead of schedule. For more on how borrowing amounts are calculated, see our guide to how much you can borrow for a personal loan.

Using a Broker to Compare Options

A licensed financial adviser operating as a lending broker can compare both secured and unsecured options across a panel of lenders on your behalf. This can be useful if you are unsure which structure suits your situation, or if you want to understand how your application is likely to be assessed before submitting it.
