How to know whether your motorhome needs a Warrant of Fitness or Certificate of Fitness

Motorhomes include many different types of vehicles, ranging from van and bus conversions to purpose-built vehicles. The standards and safety requirements for your motorhome will depend on its vehicle class. This is determined by its weight and purpose:

  • If your campervan has a Gross Vehicle Mass (GVM) of 3500 kg or less, it will require a Warrant of Fitness, the same as a conventional family car.
  • If your motorhome has a Gross Vehicle Mass (GVM) of 3501 kg or more, it will need a Certificate of Fitness. Commercial passenger vehicles of any weight, taxis and rental cars also require a CoF.

 

What is a Warrant of Fitness for a motorhome?

A Warrant of Fitness is an official document that certifies your vehicle meets the required New Zealand road safety standards. It is issued to passenger cars and light commercial vehicles weighing 3500 kg or less. A WoF can only be issued by a certified WoF inspector. Depending on where you have this done, the cost can vary, but budget for a minimum of $60.

How often you will need to have your WoF renewed depends on when your motorhome was first registered:

  • First registered 1999 or earlier - every 6 months.
  • First registered 2000 or later – annually.
  • Motorhomes less than 3 years old - not required until the third anniversary of registration.
  • New motorhomes - after the first inspection, new vehicles don’t require another WoF until the third anniversary of registration.

It is illegal to drive your motorhome if:

  • the WoF certification has lapsed
  • the WoF label is not displayed
  • your motorhome doesn’t meet WoF requirements.

  • structural condition (rust or other damage isn't allowed in certain areas)
  • lights (are all bulbs working and are your headlights aligned?)
  • glazing (is your windscreen safe and clear?)
  • windscreen washers and wipers (do they work and are they clean?)
  • doors (are they secure and do they open and close safely?)
  • safety belts (must not be faded or damaged; buckles must work properly)
  • airbags, anti-lock brakes and electronic stability control
  • speedometer (must be working)
  • steering and suspension (must be safe, secure, and effective)

  • The WoF process can usually be done fairly quickly, in around 15-20 minutes.
  • The process of obtaining a WoF is familiar and easy for most vehicle owners.
  • Any motorhome that requires a WoF can be driven on a standard Class 1 full car licence (this applies to any motorhome up to a GVM of 6000 kg).

 

What is a motorhome Certificate of Fitness?

Similar to a Warrant of Fitness, a Certificate of Fitness is to certify that your motorhome meets the required New Zealand road safety standards. The key difference is that a CoF is performed on heavier vehicles, those that weigh 3501 kg or more. As such, the inspection differs somewhat from that of a WoF.

Depending on where you have this done, the cost can vary from $150 – $250. A CoF must be renewed every six months.

  • Just as with a WoF, it is illegal to drive your motorhome if:
  • the CoF certification has lapsed

Benefits of owning a motorhome that needs a certificate of fitness

Because motorhomes that require a CoF have a higher GVM, they also have a higher payload. This makes a CoF motorhome a good option if you travel with a lot of gear. Likewise, a CoF motorhome may be preferred if you like to go off-grid for extended periods as you’ll be able to carry bigger water tanks.

 

How to prepare for a Warrant of Fitness or Certificate of Fitness

  • Lights: Check that all of your lights are in good working order. This includes the indicators, park lights, brake lights, and headlights – both dipped and high beam. Get a friend to help you, or park your motorhome in front of a window so you can see the reflection of the lights.
  • Wipers: Make sure these are working properly and that the windscreen-washing function is in good working order. Check that when you use the wipers and liquid your window is left clean and smear-free.
  • Seatbelts: These should be in good working condition and free from tears or rips. If possible, remove any child safety seats.
