Warrant of fitness (WOF) NZ: Everything you need to know

Quick answer: A WOF confirms your vehicle passed a basic road safety check. It is not a full mechanical assessment or a pre-purchase inspection.

A Warrant of Fitness, commonly called a WOF, is a regular inspection that checks whether a vehicle meets New Zealand’s required safety standards. Privately used cars, utes, vans and four-wheel drives generally need a current WOF to be driven or parked on public roads.

A valid WOF shows that an approved inspector considered the vehicle roadworthy at the time of the inspection. It does not guarantee the car will remain safe until the expiry date, so you are still responsible for keeping it in WoF condition between checks.

How often your vehicle needs a WOF depends on its age and the date of first registration, regardless of where it was registered.

‍

These rules apply based on the vehicle’s first registration in New Zealand or overseas. You can find the next expiry date on the WOF label displayed inside the front windscreen.

Important: New Zealand’s light vehicle inspection rules will begin changing from 1 November 2026. Eligible light vehicles registered on or after 1 November 2019 will move from annual to two-yearly WOF inspections. Older vehicles registered before 1 January 2000 will move from six-monthly to annual inspections.

A WOF inspection is a regular check to ensure that your vehicle meets New Zealand’s required safety standards. It examines safety-related components rather than every area of a vehicle’s condition.

The inspector will check:

• Tyres: Overall condition and whether each tyre has sufficient tread depth.
• Brakes: Whether the braking system operates effectively.
• Steering and suspension: Components must be safe, secure and working correctly.
• Vehicle structure: Structural areas are checked for unsafe damage or rust.
• Lights: Headlights, brake lights, indicators and other required lights must work.
• Windscreen and glazing: Glass must provide safe visibility and meet damage requirements.
• Wipers and washers: These must clear the windscreen effectively.
• Doors: Doors must open, close, and remain properly secured.
• Seatbelts: Belts, webbing and buckles must be safe and functional.
• Airbags: Airbag systems are checked where fitted.
• Speedometer: It must operate correctly.
• Exhaust: There must be no leaks, and it cannot be smoky or louder than the vehicle’s original exhaust system.
• Fuel system: It must not have any fuel leaks.

Modified vehicles may also need a low-volume vehicle certificate before they can meet WOF requirements.

What a WOF does not check

A WOF is not a pre-purchase inspection or a full mechanical assessment. A vehicle may pass its WOF while still having mechanical faults or upcoming repair costs.

The inspection does not generally assess:

• The condition of the engine, clutch, gearbox or differential
• Oil and other lubricant levels or conditions
• The remaining lifespan of brake pads, unless they are visibly unsafe
• Paintwork or cosmetic damage
• Rust that does not affect a structural area
• The vehicle’s overall reliability or value

A valid WOF only confirms that the vehicle met the applicable safety requirements at the time of its inspection. It remains your responsibility to keep your vehicle safe to drive between inspections. For example, tyres may pass initially but need to be replaced once the tread reaches the minimum legal depth.

There is no fixed government price for a WOF inspection. Each provider sets its own fee, so the cost can vary by inspection site, vehicle type and location.

‍

Prices change, so check the current fee with your chosen garage, VTNZ branch or other approved WOF agent before arriving. AA, for example, currently lists different rates for members and non-members.

The inspection itself is generally quick, but allow extra time during busy periods or when booking is required. If the vehicle fails its WOF, you will receive a list of issues that need attention. Once the repairs are complete, take the vehicle back for another WOF inspection.

A passed WOF is valid until the expiry date shown on the label inside your front windscreen. Your inspection frequency still depends on the vehicle’s date of first registration, including whether it was first registered in New Zealand or overseas.

Yes. You can renew a WOF before it expires. When the vehicle passes its inspection within 14 days of the current expiry date, the remaining validity carries over. The new WOF period starts from the existing expiry date, so you do not lose those remaining days.

When you renew more than 14 days early, the new expiry period is generally calculated from 14 days after the date the vehicle passes. If the current WOF has already expired, the new period starts from the date it passes the inspection.

The expiry period may also depend on when the vehicle was first registered anywhere in the world. For example, an initial WOF issued within two years of first registration may run until the third anniversary of that registration date. COF vehicles follow separate expiry rules.

A WOF, vehicle licence and Certificate of Fitness serve different legal purposes, even though they are often confused.

‍

A WOF or COF checks roadworthiness, while rego is the recurring licence fee that allows the vehicle to be used on the road. Registration is different again: it is generally a one-off process completed when the vehicle enters New Zealand.

For most private cars, a current WOF is required before the rego can be renewed. New vehicles usually receive an initial inspection, and another WOF inspection will not be required until the third anniversary of their first registration. After that, the inspection schedule depends on the applicable WOF rules.

Put simply: The WOF checks whether your car is safe, the rego confirms its road licence is paid, and a COF is the inspection used for certain commercial and heavy vehicles.

You can sell a car without a current WOF in New Zealand, but the buyer and seller should agree to this in writing.

Unless another arrangement is agreed:

• A light vehicle must have a WOF issued less than one month before the sale.
• A heavy vehicle requiring a WOF must have a current WOF.
• A vehicle requiring a COF must have a current COF.

The written agreement should clearly state that the buyer accepts the vehicle with an expired WOF or a WOF that is more than one month old. Include the vehicle details, sale date and signatures of both parties, then keep a copy of each.

A buyer who accepts a vehicle without a current WOF cannot use it for normal driving. It may only be driven somewhere for inspection or repairs, provided it is safe to make that trip.

Can I drive with an expired WOF to an inspection?

You may drive a vehicle with an expired WOF directly to an inspection or repair appointment, provided it is safe to drive. You cannot use it for everyday trips. If it fails the WOF, the same restriction applies until the required repairs and recheck are completed.

Can I park a car with an expired WOF on a public road?

Generally, no. You must display a current WOF label inside of your front windscreen. Keep an expired vehicle on private property unless you are taking it directly for an inspection or repair.

Does a WOF inspection check the engine and transmission?

No. A WOF focuses on safety-related components rather than the vehicle’s complete mechanical condition. It does not replace a mechanical or pre-purchase inspection covering the engine, transmission, clutch or overall reliability.

When does a new car need its initial WOF inspection?

New vehicles first registered anywhere in the world generally receive an initial WOF that runs until the third anniversary of their first registration. Another WOF inspection will not be required before that date, after which the relevant inspection frequency applies. Some vehicles then move to annual WOF inspections, depending on the current rules and registration date.
