My car isn't worth much but I still owe money on it. Would third-party insurance leave me exposed?
Yes — third-party insurance could leave you significantly exposed if your car is worth little but you still owe money on it. In New Zealand, the key issue is that your loan doesn't disappear just because your car is written off or stolen.
The good news is that third-party cover can still make sense for a low-value car, depending on how much you owe, what you can afford to lose, and whether you could manage without the car.
What happens in different scenarios?
| Situation | Third-party only | Comprehensive insurance |
|---|---|---|
| You damage someone else's car | Usually covers the damage you cause, subject to your policy | Usually covers this too |
| Someone damages your car and is at fault | You may be able to recover costs from them, if liability can be established | Your own insurer can generally handle the claim under your policy terms |
| You cause an accident and your car is badly damaged | You pay to repair or replace your own car | Your insurer may cover your car, subject to your excess and policy terms |
| Your car is stolen | You generally get no payout for your own car | Theft is generally covered, subject to policy terms |
| Your car is written off | You still owe the outstanding loan | You still owe the loan, but an eligible insurance payout can help repay it |
The biggest risk: you could lose the car, still owe thousands of dollars to your lender, and have to find money for another vehicle.
A simple example
Your car's current value
$4,000
Your outstanding loan
$8,000
Potential shortfall if the car is written off
$8,000
With third-party only, you could receive no payout for your own car and still owe the full $8,000. With comprehensive cover, a hypothetical $4,000 payout could reduce the debt to $4,000, before any applicable deductions.
That is the core problem: the amount you owe and the amount your car is worth are two different things. Even comprehensive insurance might not clear the loan if you owe more than the car's insured value. Car insuranceInsuranceWhat Happens if Your Car is Written Off in NZ?
What I'd consider in your position
- Third-party only: Makes sense if the car is cheap to replace and you could still manage your loan if the car were destroyed or stolen.
- Third-party, fire and theft: A middle ground if you mainly want protection against theft and fire, but can afford the risk of accidental damage to your own car.
- Comprehensive: Worth considering if losing the car would leave you paying off a loan for a vehicle you can no longer use. Check whether your finance agreement requires this cover, too. Car insurance buying guideGetting a loan for your car
You could also ask whether gap insurance is available and suitable for your situation. It may cover some or all of the difference between an eligible insurance payout and your outstanding loan, depending on the policy. Insurance
