Legality of mods in accidents

[Timbo]

In a case like this, it is not necessarily an issue for your car insurer, but for your third party (Green Slip) insurer. They will be guided by the police report -- particularly any indication that the vehicle may have been defective in a way that is relevant to the accident. That means, as Aaron says, that a modified part contributed to the accident. In the case of a death, there may be a coronial inquest, and the examination will be thorough. No police 'discretion'. If this is the case, then there's a whole range of that'll come down.

Wheels, tyres, brakes, suspension and steering are obvious areas that might be subject to scrutiny. All good reasons to avoid obvious (and potentially dangerous) mods such as stretched tyres, spacers, totally dumped suspension...
