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 (WoF) inspections, are:

  • CoF A (Light)
    All passenger service vehicles including taxis, shuttles & buses, as well as rental cars & campervans, and motorcycles.
  • CoF B (Heavy)
    All heavy vehicles including trucks, larger trailers & motorhomes over a weight of 3,500kgs.

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.
