What is a Warrant of Fitness (WOF)?

A Warrant of Fitness (WOF) is the official check in New Zealand to ensure that a vehicle is safe to drive on public roads.

It checks key safety components such as:

Brakes
Steering
Suspension
Lights and indicators
Tyres
Seatbelts
Windscreen and mirrors

A vehicle must pass a WOF check to be legally driven on public roads.

Who Needs a WOF?

All vehicles over 6 months old must undergo regular WOF inspections.

Vehicles include:
- Cars
- Light commercial vehicles
- Motorcycles
- Trailers (in certain cases)

Note: New vehicles may be exempt from WOF checks for the first 3 years, depending on vehicle type.

How Often is a WOF Required?

The frequency of WOF inspections depends on the vehicle’s age and type:

Vehicle Type	Frequency
Vehicles < 6 years old	Every 12 months (some light vehicles may vary)
Vehicles > 6 years old	Every 6 months
Trailers	Every 12 months (if registered for road use)

Always check NZTA rules — frequency may change for EVs, hybrids, or trailers.

Why WOF is Important

Ensures your vehicle is roadworthy
Reduces the risk of accidents
Protects drivers, passengers, and pedestrians
Required by law to avoid fines or impoundment

How Much Does a WOF Cost?

WOF fees vary depending on:

Vehicle type
Location of inspection
Private vs approved garages

Typical cost range:

Cars and light vehicles: ~$50–$70
Trailers: ~$25–$50

Prices may differ slightly depending on region and garage.

How to Get a WOF

Take your vehicle to an authorised WOF inspection station
Vehicle is checked for safety compliance
Pass or fail issued
If failed, repair is required before the WOF is issued
Pass: You get a WOF certificate valid for 6–12 months
Fail: You must fix the issues and get the vehicle rechecked

Expired WOF – What Happens?

Driving with an expired WOF is illegal
Fines may apply
Insurance may not cover accidents
Vehicle could be impounded in severe cases

Always check your WOF expiry date and set reminders.

Buying or Selling a Vehicle – WOF Rules

For Sellers:

Must disclose current WOF status
Provide certificate if available

For Buyers:

Ensure vehicle has valid WOF
Check for upcoming expiry dates
Consider scheduling a new WOF check for safety assurance

WOF is transferable to new owners as long as it is still valid.

Edge Cases and Special Situations

Imported vehicles: Must meet NZ safety standards before WOF is issued
Written-off vehicles: May require additional inspection
Classic or project cars: Can have flexible WOF scheduling, but must pass before driving on public roads
Modified vehicles: Require LVV certification before passing WOF

Frequently Asked Questions (FAQ)

Q: What happens if my WOF fails?

A: You must fix the faults and have it re-inspected. You cannot legally drive it until it passes.

Q: How long is a WOF valid for?

A: Typically 6 or 12 months depending on vehicle age.

Q: Can I get a WOF at any garage?

A: No — only at NZTA-authorized inspection stations.

Q: Do new cars need WOF?

Part 2 – Detailed WOF Process & Vehicle Safety Checks

How a WOF Inspection Works

A WOF inspection ensures your vehicle meets minimum safety standards.

Key areas checked include:

Brakes – Pads, discs, handbrake, and brake fluid
Steering & Suspension – No excessive play, shocks functioning
Tyres & Wheels – Minimum tread depth, no significant damage
Lights & Indicators – Headlights, brake lights, hazard lights
Windscreen & Mirrors – No cracks affecting visibility
Seatbelts – Functioning, no tears
Body & Chassis – No excessive rust or structural damage
Exhaust & Emissions – Safe exhaust, compliance with emissions rules

Vehicles failing in any of these areas will not pass the WOF until repairs are completed.

Step-by-Step WOF Inspection

Drive to an authorized WOF station
Vehicle is physically examined for each safety component
Inspector issues:
- Pass → WOF certificate valid for 6–12 months
- Fail → Faults are listed; vehicle must be repaired and re-inspected
Repairs can be done at the same station or another approved garage

WOF and Vehicle Age

Vehicles under 6 years old: Typically 12-month WOF
Vehicles over 6 years old: Usually require 6-month inspections
Trailers: Require 12-month WOF if registered for road use
Imported or modified vehicles: Additional checks may apply

Common WOF Failures

Brake issues – worn pads, leaks, uneven braking
Tyres – low tread depth, cracks, uneven wear
Lights not functioning – brake, indicator, or hazard lights
Steering/Suspension faults – worn bushes, shock absorbers
Seatbelts – missing or damaged
Structural rust – especially around chassis, sills, and wheel arches

Knowing common failures can help you pre-check your vehicle before inspection.

Cost of a WOF

Cars and light vehicles: ~$50–$70
Trailers: ~$25–$50
Repairs are additional if the vehicle fails
WOF costs are generally lower than fines or accident-related costs

Tip: Pre-checking your car saves money and time.
