When borrowing in New Zealand, most personal loans are either secured (backed by an asset) or unsecured (no collateral required). The difference affects your interest rate, borrowing limits, approval odds, and what happens if you can’t repay.
Secured loan: Lower rate, larger limits — but the lender can repossess your asset if you default
Unsecured loan: Higher rate, simpler process — but no asset at risk if you can't repay (though your credit score and income are still at risk of enforcement action)
Secured Loans
A secured loan requires you to offer an asset as collateral. If you default on the loan, the lender can repossess and sell that asset to recover their money.
Common assets used as security in NZ:
- Motor vehicles (most common for personal secured loans)
- Property equity (via a mortgage top-up)
- Savings/term deposits (used as security for personal loans in some cases)
- Boats, motorcycles, caravans
Benefits of secured loans:
- Lower interest rates (typically 2–5% lower than unsecured)
- Higher borrowing limits
- Easier approval if you have marginal credit history
- Longer terms possible
Risks of secured loans:
- The lender can repossess your vehicle (or other asset) if you stop paying
- PPSR registration — the loan is registered against the vehicle on the Personal Property Securities Register, meaning the car can’t be sold until the loan is repaid
- If the vehicle is written off (accident, fire, theft), you need insurance to cover the remaining balance
Unsecured Loans
An unsecured loan has no asset backing. The lender takes on more risk, which is why rates are higher.
Benefits of unsecured loans:
- No asset at risk
- Simpler application process (no PPSR registration, no asset valuation)
- Suitable for purposes where no asset exists to offer (medical bills, holiday, debt consolidation with no vehicle)
Risks of unsecured loans:
- Higher interest rates
- Lower borrowing limits
- Stricter income and credit requirements for approval
- If you default, the lender still has legal recourse — debt collection, court judgment, wage garnishment
Rate Comparison: Secured vs Unsecured
Typical rate difference between secured and unsecured loans from the same NZ lender:
| Loan type | Rate range | Notes |
|---|---|---|
| Secured personal loan (vehicle) | 9–15% p.a. | Asset registered on PPSR |
| Unsecured personal loan | 11–20% p.a. | Higher rate, no collateral |
| Secured against property equity | 6–12% p.a. | Effectively a home equity loan |
Which Type of Loan Is Right for You?
Choose secured if:
- You have a vehicle or other asset to offer as security
- You want the lowest possible rate
- Your credit history is not perfect (security improves approval odds)
- You need to borrow a larger amount ($15,000+)
Choose unsecured if:
- You don’t own an asset free of other finance
- You want simplicity — no PPSR paperwork
- The loan purpose doesn’t involve purchasing an asset
- Your credit is strong and you qualify for competitive unsecured rates anyway
Car Finance: A Special Case
When buying a car with finance, the vehicle being purchased typically becomes the security for the loan. This is standard practice — whether through a bank car loan or dealer finance. The PPSR registration on the vehicle means:
- You can’t sell the car without paying out the loan (or the buyer inherits the liability)
- Always check the PPSR (at ppsr.govt.nz) before buying a used car to ensure no existing finance is registered against it
PPSR — Personal Property Securities Register
The PPSR is New Zealand’s register of security interests in personal property (everything except real estate). When a lender takes security over a vehicle or other personal property, they register it on the PPSR.
For borrowers: Your vehicle will be on the PPSR for the duration of the loan. This is standard and expected.
For used car buyers: Always check the PPSR (free search at ppsr.govt.nz) before buying a used vehicle. If there’s an existing security interest and the seller doesn’t pay it out from the sale proceeds, the finance company can repossess the car from you even as the new owner.
