WOF Inspections in New Zealand — A Complete Guide

If you own a vehicle in New Zealand, you'll need to get a Warrant of Fitness (WOF) regularly. It's a legal requirement that checks your car is safe to be on the road. This guide covers everything you need to know — from when you need one to what happens if you fail.

What is a WOF?

A Warrant of Fitness is a certificate issued after a vehicle passes a safety inspection. It confirms your car meets minimum safety standards set by Waka Kotahi NZ Transport Agency.

Think of it like a health check for your car. It's not about mechanical perfection — it's about ensuring your vehicle isn't a danger to you or other road users.

When do you need a WOF?

Your WOF frequency depends on your vehicle's age:

  • New vehicles — first WOF is due at 3 years from first registration
  • Vehicles 3–6 years old — WOF every 12 months
  • Vehicles over 6 years old — WOF every 6 months

If you drive a heavy vehicle (over 3.5 tonnes) or a rental vehicle, different rules apply. Check with Waka Kotahi for specific requirements.

How does a WOF inspection work?

Your vehicle is checked against a standard checklist. Here's what the inspector looks at:

  • Tyres — tread depth, condition, and pressure
  • Brakes — performance and condition
  • Suspension and steering
  • Lights and reflectors
  • Windscreen and windows — no cracks blocking vision
  • Wipers and washers
  • Seatbelts — all must work properly
  • Doors and latches
  • Body and chassis — no serious rust or damage
  • Exhaust system — no leaks and not too loud
  • Speedometer — must be accurate

The inspection usually takes 30–45 minutes. You can wait at the garage or drop it off and come back.

Step-by-step guide to getting a WOF

Step 1: Check your WOF expiry date

Look at the sticker on your windscreen or check your vehicle registration documents. You can also use the Waka Kotahi online vehicle checker.

Step 2: Do a quick pre-check yourself

Before you take your car in, check the basics: tyre tread, lights, wipers, and seatbelts. A simple check can save you a failed inspection and a recheck fee.

Step 3: Book an appointment

Find a WOF inspection station near you. Many garages, tyre shops, and service centres offer WOFs. Book ahead — especially if you're due soon.

Step 4: Bring the right documents

You don't need much — just your car. But if you've had modifications (like a lift kit or aftermarket wheels), bring documentation proving they're certified.

Step 5: The inspection

The inspector will check your vehicle against the standard checklist. They may drive it briefly to test brakes and steering.

Step 6: Pass or fail

  • Pass — you'll get a new WOF sticker and certificate. The expiry date will be printed on the sticker.
  • Fail — you'll get a failed inspection report listing what needs fixing. You have 28 days to get repairs done and a free recheck at the same station.

Step 7: Display the sticker

Put the new WOF sticker on your windscreen (driver's side, bottom corner). Keep the certificate in your glovebox.

WOF costs

WOF prices vary by region and garage. Expect to pay:

Vehicle type Typical cost range
Cars and light vehicles $50–$70
Motorcycles $30–$50
Heavy vehicles $80–$120

Some garages offer discounts for booking online or bundling with a service. Always ask about the price before booking.

What happens if your WOF expires?

Driving without a current WOF is illegal. If you're caught, you can get a fine of up to $400. Your vehicle could also be impounded.

If your WOF expires while your car is parked off-road (like in your driveway), you can't drive it on public roads until it passes. You'll need to get it towed to a garage or arrange a mobile WOF inspection.

Common reasons for WOF failure

Here are the most common issues that cause a fail:

  • Worn or damaged tyres (tread below 1.5mm)
  • Broken or dim lights
  • Windscreen chips or cracks in the driver's line of sight
  • Worn wiper blades
  • Brake issues
  • Rust in structural areas
  • Loose or missing seatbelts
  • Exhaust leaks or excessive noise

Most of these are cheap to fix if caught early. Regular maintenance helps avoid surprises.

Tips for passing your WOF

  • Check your tyre pressure and tread before the inspection
  • Top up your windscreen washer fluid
  • Make sure all lights work — including indicators and brake lights
  • Clean your windscreen inside and out
  • Remove any loose items from the car
  • If your check engine light is on, get it checked first
  • Keep your service history handy — it shows you've maintained the car

What if you disagree with a WOF result?

If you think your vehicle was unfairly failed, you have options:

  • Talk to the garage manager first — sometimes it's a misunderstanding
  • Get a second opinion from another inspection station
  • Contact Waka Kotahi if you believe the inspection was not done properly

Remember, a recheck is free within 28 days at the same station. If you go somewhere else, you'll pay for a full new inspection.
