COF & WOF
« back
Your motor caravan will require either a Certificate of Fitness (COF) or a Warrant of Fitness (WOF) depending on the manufacturer's gross laden weight.
Your Motor Caravan is Under 3500 kgs:
The vehicle requires a WOF; which are obtained from approved private garages and Vehicle Testing Stations; the requirements are the same as for a private car.
If a NA class (under 3500 kg’s manufacturer’s gross laden weight rating) motor caravan is classed as a modified vehicle it will require a Declaration Form or a Low Volume Vehicle Certificate to obtain a WOF.
A declaration form is required where the vehicle has been modified from standard e.g. where the engine has been changed from standard petrol to a diesel, using the same mountings, and the power output does not exceed 10% more than the original.
A Low Volume Vehicle Certificate is required where the motor caravan has been modified and it affects the Vehicle Standards Regulations (VSR's). If any Member requires information on this they should contact a Low Volume Vehicle (LVV) Certifier.
Your Motor Caravan is Over 3500 kgs:
You will be required to obtain a Certificate of Fitness (COF).
If your vehicle has a manufacturer's gross laden weight rating between 3,500 kg and 3,750 kg - but weighs less than 3,500 kg fully laden - you will be able to apply for an exemption from the COF requirements, providing it was first registered in New Zealand before January 1992 and complies with the Low Volume Vehicle Code. Applications may be made to the New Zealand Transport Agency.
If your vehicle has a manufacturer's gross laden weight rating between 3,500 kg and 3,750 kg - but weighs less than 3,500 kg fully laden - you will be able to apply for an exemption from the COF requirements, providing it was first registered in New Zealand before January 1992 and complies with the Low Volume Vehicle Code.

If your vehicle's manufacturer's gross laden weight is over 3,750 kg but now weighs less than 3,500 kg when fully laden you will still be required to obtain a COF.
