Have you failed your Warrant of Fitness (WOF)?


In New Zealand, all cars must legally show a valid Warrant of Fitness “WOF” label on the windscreen. Failure to show a WOF label can result in a fine. A failed Warrant of Fitness can be stressful as it means that you cannot legally drive your car until it has been fixed by a mechanic. Fortunately, we want to make the process of getting your WOF certification as straightforward and simple as possible.

At Grimmer Motors, we want you to be able to get your vehicle back on the road as soon as possible. For this reason, we provide our customers with reliable, high-quality WOF repair work. 


Common reasons for a failed WOF

If the CV joint or the CV boot become damaged then you may fail a Warrant of Fitness (WOF). At Grimmer Motors we can look after all your cv joint repair and replacement needs.

Safety Belt Failed WOF

Safety belts are designed to protect you and the other passengers in your vehicle in the event of an accident by restricting your forward motion during a sudden stop or vehicle impact. Most modern cars use safety belt pre tensionsers to tighten the safety belt the instant a crash is detected, to prevent your upper body and head hitting the steering wheel or wind screen. Sometimes the webbing on the safety belt start to frey or come apart or the safety belt buckle / latch won’t click and hold in place properly, causing you to fail a Warrant of Fitness. Another common fault is the safety belt ratchet mechanism won’t lock the safety belt when it is pulled out quickly.

At Grimmer Motors we have the experienced and qualified team of mechanics to quickly and reliably provide quality safety belt repairs for your vehicle.

Steering & suspension failed WOF

The suspension is the system of springs, shock absorbers (shocks), ball joints, tie rod ends, bushes, sway bar links, and bearings that allows relative motion between the vehicle frame and the wheels.
