NZ Insurance & Misfuel Claims: What's Covered & How to Claim

Putting the wrong fuel in your car happens more often than you'd think. Whether it's petrol in a diesel tank or diesel in a petrol engine, knowing how your insurance handles misfuel claims can make a stressful situation much more manageable.

Most major New Zealand insurers including AMI, State Insurance, AA Insurance, Vero, and Tower treat misfuelling as an accidental damage claim under comprehensive cover. This typically includes the cost of fuel drain and flush services, plus any mechanical damage caused by running contaminated fuel through your engine. However, coverage varies significantly between policies and insurers.

AMI and State Insurance generally cover misfuel incidents as part of their comprehensive policies, but you'll need to pay your excess. AA Insurance often includes misfuel cover in their premium packages, while Vero and Tower assess claims case-by-case depending on your specific policy terms. The key factor is whether you started the engine after misfuelling – running contaminated fuel can cause expensive damage to fuel pumps, injectors, and engine components.

To claim, you'll need to contact your insurer immediately and provide details about what happened. Most insurers require you to use their approved repairers and may ask for photos or receipts. Keep all documentation from the fuel station if possible, including your receipt showing the fuel type purchased.

The claims process typically involves an assessment to determine the extent of contamination and any mechanical damage. Simple fuel drain and flush jobs are straightforward, but if you've driven the vehicle or started the engine multiple times, expect more extensive repairs and higher costs.

What to do right now

If you've just misfuelled, don't panic but don't start the engine. This is absolutely critical – starting the engine circulates contaminated fuel throughout the system, potentially turning a simple drain job into major engine repairs costing thousands.

Call your insurer first to understand your coverage, then arrange professional help. Even if your insurance doesn't cover misfuel claims, getting the problem fixed quickly prevents more expensive damage.
