Why do Trailers need WoFs?

In order to legally use a trailer on New Zealand roads, the trailer must have an appropriate Warrant of Fitness certification. This ensures that the trailer’s lights, wheel bearings, tyres, tow bar couplings, and reflectors are functioning properly, improving everyone’s safety.

It’s very easy to hook up your trailer and use it without thinking to check if it has a current WoF or registration. However, you may be at risk of fines or potential safety issues if the WOF has expired. Keep you, your family, and others safe on the roads, plus avoid the risk of your trailer parts breaking down,  or getting a fine, by ensuring your trailer has a registration and WoF as soon as possible.


Types of trailer WOFs

A standard trailer WoF covers most types of trailers found on New Zealand roads. A standard trailer is identified by its single axle. Common types of standard trailer include:

  • Light trailers
  • Small caged trailers
  • Boat trailers

A commercial (or full) trailer has two axle sets and is used for transporting heavier equipment such as bulk supplies and other vehicles.
