Every question, every answer, every source

If your parked car was damaged in the Auckland floods, you don't have to accept a repair proposal without first understanding whether the car is safe, whether the damage has been properly assessed, and whether a write-off settlement is available under your policy.

Flood damage can be particularly concerning because water may affect electrical systems, safety features, bearings and engine components, sometimes with faults appearing weeks or months later.

In New Zealand, you can challenge an insurer's assessment and ask for the evidence behind its decision. The key is to act before authorising repairs or agreeing to a settlement.

What to do now

1. Document the flood damage

Photograph any waterlines, wet carpets, damp upholstery, warning lights and visible damage. Keep towing receipts, inspection reports and all messages from the insurer. Don't start or drive the vehicle if water may have reached the engine or electrical systems.

2. Request the full assessment in writing

Ask the insurer for the assessor's report, the estimated repair cost, the proposed scope of work, and details of any flood-related electrical, mechanical, corrosion or safety checks. Ask how they have ruled out hidden damage.

3. Get an independent assessment

Consider asking a qualified mechanic or vehicle assessor who is independent of the insurer and repairer to inspect the vehicle. Ask specifically whether the flood damage could make the vehicle uneconomic or unsafe to repair, and whether the proposed repairs address hidden damage.

4. Ask the insurer to reconsider a write-off

Request a written explanation of its repair-versus-write-off decision. Ask what valuation it has used for your car, how it calculated the repair costs, and whether the estimate includes the possibility of additional damage discovered during repairs.

Can you insist that the car is written off?

Not automatically. In New Zealand, the insurer's decision generally depends on your policy terms, the cost-effectiveness of repairs and whether the vehicle can be repaired safely. You can challenge that decision with evidence, but simply preferring a payout may not oblige the insurer to write it off.

Waka Kotahi (NZTA) specifically warns that drying a flood-damaged vehicle is not enough to establish its safety, because electronic and mechanical safety systems may have been affected. Water damaged vehicles

A few things to establish:

• Agreed value or market value: Check which basis your policy uses and how the insurer calculates a total-loss settlement.
• Repair cost versus vehicle value: Request the actual figures and ask whether further damage could increase the cost.
• Safety: Ask for evidence that the vehicle can be repaired safely, including appropriate checks for flood-related damage.
• Your policy wording: Some policies give the insurer the choice of repairing the vehicle or settling it as a total loss, subject to specified conditions.

A car can be technically repairable but still uneconomic to repair. Conversely, flood exposure alone does not automatically mean every vehicle must be written off.

If the insurer won't reconsider

1. Make a formal complaint to the insurer. State that you dispute the repair decision and ask for a fresh review by another assessor. New Zealand Consumer Protection recommends asking the insurer to review a claim if you disagree with its outcome. Insurance
2. Escalate to the insurer's independent dispute resolution scheme if the complaint isn't resolved. Depending on the insurer, this may be the Insurance & Financial Services Ombudsman Scheme (IFSO), Financial Services Complaints Ltd (FSCL), or another approved scheme. These services are free for eligible complaints. Making a complaint about your financial service providerDisputes and consumer protectionMake a complaint
3. Keep everything in writing. Save the policy, assessor's report, repair estimate, photos, independent reports and all correspondence.

Subject
: Formal request to review flood-damaged vehicle assessment

Kia ora,

I am writing regarding my vehicle, which was damaged in the Auckland floods, and your current proposal to repair it.

I am concerned that the proposed repairs may not adequately address the full extent of the flood damage, including any hidden electrical, mechanical, corrosion or safety-related issues.

Before I authorise or agree to the proposed repairs, please provide:

• A copy of the full assessor's report and repair estimate.
• Details of the inspections and tests carried out to assess flood-related damage.
• Your reasons for determining that repair is appropriate rather than treating the vehicle as a total loss.
• The vehicle valuation and repair-cost calculations used in reaching that decision.
• Confirmation of how any additional damage discovered during repairs would be assessed and covered.

I would also like to request a review by another assessor, taking into account the potential for hidden flood damage and the vehicle's long-term safety and reliability.

Please record my concerns on the claim and advise me of the formal complaints process if we cannot resolve this matter.

I look forward to receiving your written response before the repair work proceeds.

Kind regards,

[Your name] [Claim number] [Vehicle registration]

Let me help you assess your specific case

The most important detail is whether the insurer is proposing repairs despite substantial water exposure, or whether it has already assessed the car as repairable based on an estimate.

What make and model is your car, and how high did the floodwater reach? For example, just the wheels, the bottom of the doors, the seats, or the dashboard.

With that information, I can help you identify the key warning signs of a potential write-off and the strongest questions to put to your insurer.
