Could anyone tell me the difference between a Certificate of Fitness and a Warrant of Fitness
Depending on the gross laden weight of the vehicle it will either need a COF or WOF safety inspection. COF is generally for heavier vehicles with a gross laden weight exceeding 3500kg like trucks, motor homes, large trailers as well as all passenger service vehicles (taxi's, buses ,etc.). See NZTA website WOF or COF for more information.
