A failed WOF (Warrant of Fitness) is rarely caused by one big dramatic fault. More often, it\’s a handful of small, gradually-worsening issues that finally cross the line into \”doesn\’t meet the standard.\” Knowing the most common failure points can help you catch them before your next inspection rather than being surprised by them at the testing station.
1. Tyres
Tyres are one of the most frequent WOF failure points. Common issues include:
- Tread depth below the legal minimum of 1.5mm
- Cuts, bulges, or exposed cord
- Mismatched tyre sizes or types on the same axle
Checking tread depth and tyre condition yourself every few weeks is a simple habit that avoids this entirely.
2. Brakes
Brake-related failures include worn pads, low fluid, uneven braking between wheels, or a handbrake that doesn\’t hold sufficiently. Because braking performance is safety-critical, inspectors apply a strict standard here.
3. Lights
A surprising number of WOF failures come down to something as simple as a blown bulb — headlights, brake lights, indicators, or number plate lights. It\’s a quick fix, but an easy one to overlook until inspection day.
4. Windscreen and Wipers
Cracks or chips within the driver\’s direct line of sight, and wiper blades that don\’t clear the windscreen effectively, are both common fail points, especially heading into wetter months.
5. Suspension
Worn shock absorbers, bushes, or other suspension components affect handling and stopping distance. These issues often develop gradually, so drivers may not notice them day-to-day until a WOF inspection flags them.
6. Exhaust System
Excessive noise, visible smoke, or leaks in the exhaust system are all inspected. Corrosion from coastal air is a common cause of exhaust failures in Auckland specifically.
7. Structural Rust or Corrosion
Rust affecting structural areas of the vehicle — particularly around chassis rails, seatbelt mounting points, or suspension mounts — is treated seriously, since it relates directly to the vehicle\’s structural safety.
8. Seatbelts
Frayed, cut, or non-retracting seatbelts, or mounting points that aren\’t secure, will fail a WOF. These are quick to check yourself before your appointment.
Frequently Asked Questions
How can I reduce the chance of failing my WOF?
Regular servicing catches most of these issues early. A quick self-check of tyres, lights, and wipers before your appointment also helps avoid easily-preventable fails.
What happens if my car fails a WOF?
You\’ll be given a list of the specific faults. Once they\’re repaired, the vehicle can be re-inspected, often at a reduced or no additional cost within a set period depending on the testing station\’s policy.
How often does a vehicle need a WOF in New Zealand?
This depends on the vehicle\’s age and registration date — newer vehicles are generally inspected annually, while older vehicles typically require a WOF every six months.
