Certificate of Fitness (CoF)

A Certificate of Fitness (CoF) is a regular check to ensure that your vehicle meets required safety standards.

Intro Image

New Zealand law requires all commercial transport vehicles, and any heavy vehicle over a weight of 3,500kgs, to be inspected regularly for a Certificate of Fitness (CoF).

Vehicles requiring this type of certification, rather than the more common "Warrant of Fitness" or WoF inspections, are:

  • heavy vehicles - trucks, larger trailers, motor homes
  • all passenger service vehicles - taxis, shuttles and buses
  • rental vehicles.

CoF expiry dates
Your Certificate of Fitness starts from the date your vehicle passes the inspection. However, if you bring your vehicle to us a few days before your current CoF expires (up to a maximum of 28 days), we can extend the expiry date of your new CoF equal to the number of days you had left on the old one.
