Keeping your car roadworthy is essential in New Zealand, and passing your Warrant of Fitness (WoF) is a legal requirement. However, many vehicles fail their inspection due to avoidable issues.

What Is a Warrant of Fitness (WoF)?

A WoF is a regular safety inspection that ensures your vehicle meets minimum road safety standards. It checks key components like brakes, tyres, lights, and structure.

Failing a WoF means your car is unsafe to drive until repairs are completed.

1. Worn or Damaged Tyres

Why it fails:

  • Tread depth below 1.5mm
  • Uneven wear
  • Cracks, bulges, or exposed cords

How to avoid it:

  • Regularly check tyre tread
  • Rotate tyres every 10,000 km
  • Replace tyres before they become unsafe

💡 Pro Tip: Use the 20-cent coin test to check tread depth quickly.

2. Faulty Lights and Indicators

Why it fails:

  • Broken headlights, brake lights, or indicators
  • Misaligned headlights
  • Non-working reverse lights

How to avoid it:

  • Check all lights weekly
  • Replace blown bulbs immediately
  • Clean foggy headlight covers

3. Brake Issues

Why it fails:

  • Worn brake pads
  • Brake imbalance
  • Soft or unresponsive brake pedal

How to avoid it:

  • Get brakes inspected every 10,000–15,000 km
  • Listen for squeaking or grinding sounds
  • Never ignore braking issues

4. Suspension and Steering Problems

Why it fails:

  • Worn shock absorbers
  • Loose steering components
  • Vehicle pulling to one side

  • Rust in structural areas
  • Damaged chassis or frame
  • Previous poor-quality repairs

How to avoid it:

  • Wash your car regularly (especially underbody)
  • Repair rust early before it spreads
  • Avoid buying poorly repaired vehicles
