WoF Explained

A Warrant of Fitness (WoF) is a regular safety inspection required for all light vehicles used on New Zealand roads. The purpose of the WoF is to ensure that vehicles meet minimum safety standards, protecting both the driver and other road users. Without a current WoF, it is illegal to drive your vehicle on public roads, and you may face fines of up to $200 if stopped by police.

What Gets Checked During a WoF?

A WoF inspection covers more than 28 individual safety items. The inspection is carried out by a licensed Vehicle Testing Station (VTS) and typically takes between 30 minutes and an hour. The key areas examined include:

• Tyres — tread depth must be at least 1.5mm across the full width of the tyre. Inspectors also check for damage, bulges, and correct sizing.
• Brakes — both the foot brake and handbrake are tested for effectiveness, wear, and fluid leaks.
• Steering and suspension — components are checked for wear, play, and damage that could affect vehicle handling.
• Lights and indicators — all headlights, tail lights, brake lights, indicators, and fog lights must be working and correctly aimed.
• Glazing — the windscreen must be free from cracks or chips in the driver's line of sight.
• Structural condition — the body, chassis, and subframe are inspected for rust, cracks, or other damage that could compromise safety.
• Seatbelts — all seatbelts must be present, working, and free from damage.
• Exhaust emissions — the exhaust system is checked for leaks and excessive emissions.
• Doors, latches, and hinges — doors must open, close, and latch securely.
• Windscreen wipers and washers — must be operational and effective.
• Speedometer — must be present and working.

How Often Do You Need a WoF?

The frequency of WoF inspections in New Zealand depends on the age of your vehicle:

• Vehicles first registered on or after 1 January 2000 — WoF required every 12 months.
• Vehicles first registered before 1 January 2000 — WoF required every 6 months.

You can get your WoF up to one month before it expires without losing any time on your next due date. This gives you a useful buffer to schedule the inspection at a convenient time.

How Much Does a WoF Cost?

WoF inspections in New Zealand typically cost between $50 and $80, depending on the testing station. VTNZ, AA, and other large chains tend to charge at the higher end, while smaller independent garages may offer lower rates. Some garages offer free re-inspections if your vehicle fails on minor items and you have the repairs done at their workshop.

Where to Get a WoF

WoF inspections can only be carried out at an approved Vehicle Testing Station (VTS). These include nationwide chains such as VTNZ and AA Auto Centre, as well as many independent garages and mechanics. You can find your nearest approved testing station using the NZTA online search tool. It is a good idea to book ahead, especially around busy times such as the end of the month.

NZTA Rules and Regulations

The WoF system is governed by Waka Kotahi NZ Transport Agency (NZTA). The rules are set out in the Land Transport (Motor Vehicle Safety) Regulations, and testing stations must follow the Vehicle Inspection Requirements Manual (VIRM). If you believe an inspection was carried out incorrectly, you can raise a complaint with NZTA or request a re-inspection at a different testing station.

Keeping your WoF current is one of the most important responsibilities of car ownership in New Zealand. If your vehicle fails its inspection, see our guide on what to do if your car fails its WoF. For a broader overview of ownership costs and obligations, visit the car ownership hub.
