What is a Warrant Of Fitness (WoF) and why is it important?

A warrant of fitness is a mandatory vehicle safety assessment in New Zealand. This certification, also known as a WoF, verifies that your vehicle satisfies the basic safety criteria required to travel legally on public roads.

All light vehicles, including cars, vans, and motorbikes, must have a current WoF to remain roadworthy in New Zealand. This requirement is critical for reducing accident rates, identifying mechanical concerns early on, and maintaining safety across the transportation system.

What Does a WoF Inspection Cover?

A certified inspector at an authorised testing centre must carry out a warrant of fitness inspection. All the vehicle's important safety systems are examined during the procedure. These consist of:

  • Brakes and brake pads
  • Steering and suspension systems
  • Tyres (tread depth must be at least 1.5 mm)
  • Lights, indicators, and reflectors
  • Seat belts
  • Windscreen, washers, and wipers
  • Doors and windows
  • Exhaust system and emissions
  • Rust, chassis condition, and general body integrity

If the vehicle passes all inspections, a WoF label is issued and displayed on the windscreen.

How Often Do You Need a Warrant of Fitness?

The frequency of your warrant of fitness depends on the age of the vehicle:

  • New vehicles: First WoF is due three years after initial registration
  • Vehicles under 20 years old: Annual inspection
  • Vehicles over 20 years old: Inspection every six months

If you are unsure about your vehicle's next due date, you can check it online using the NZTA’s registration and WoF tools.

What Happens If You Fail Your WoF?

If your car does not meet the required safety standards, it will fail the warrant of fitness examination. The inspector will submit a report outlining all of the flaws. You will have 28 calendar days to complete the repairs and return for a free re-inspection at the same location.

Your vehicle is legally forbidden from operating until the issues are resolved, with the exception of travel to and from a repairer or inspection location. Driving without a valid WoF can result in fines and may affect insurance coverage.

Is a WoF the Same as a Vehicle Service?

Routine maintenance cannot be replaced by a warrant of fitness.  

A WoF's main purpose is to ensure road safety. During the inspection, it evaluates whether your vehicle is safe to drive.  


A service is more comprehensive, covering mechanical systems like the cooling system, engine, transmission, oil, and filters. Routine maintenance, which keeps your car in good condition all year, can help prevent WoF problems.  

How to Prepare for a WoF

Here are some tips to improve the chances of passing your next warrant of fitness:  

  • Examine every light and change any damaged bulbs.
  • Check that your tyres have enough tread and are evenly worn
  • Verify that the wipers, washers, and mirrors are working
  • Check that all seat belts click in securely and retract smoothly
  • Repair any visible rust or body damage

Before the inspection, do a self-check to save time and avoid preventable failures.

A warrant of fitness is more than just a legal requirement; it also represents a commitment to responsible car ownership and safer roads. Frequent WoF checks keep your car on the road, help identify problems early on, and ensure that you contribute to public safety.
