Certification of Fitness

A certificate of fitness (CoF) is a regular check to ensure that your vehicle meets required safety standards. Vehicles requiring this certification are:

  • heavy vehicles – trucks, larger trailers, motor homes (Our site does not do heavy vehicles)

  • all passenger service vehicles – taxis, shuttles and buses

  • rental vehicles.

The CoF inspection covers a range of vehicle safety and environmental factors, including the condition of the vehicle's tires, brakes, lights, steering, suspension, and structural components. The inspection also includes an emissions test to ensure that the vehicle's exhaust emissions are within acceptable limits.


If a vehicle fails a CoF inspection, the owner is required to make the necessary repairs to bring the vehicle up to the required standard before the CoF can be issued. In some cases, a vehicle may also be issued with a "rejected" CoF if it fails to meet the minimum safety standards, in which case it must be repaired and re-inspected before it can be driven on public roads again.

Overall, the CoF is an important part of ensuring that all heavy vehicles on New Zealand roads are safe and compliant. By requiring regular inspections and ensuring that vehicles meet minimum safety and environmental standards, the CoF helps to keep drivers, passengers, and other road users safe.
