Warrant of Fitness

wof Reviewed 12 August 2026 4 min read

Short answer

A Warrant of Fitness is a periodic safety inspection, not a mechanical guarantee. There is no grace period once it expires — the infringement fee is $200 — and the only permitted use of an unwarranted vehicle is taking it for repair or for a new inspection. If it fails you get one free recheck within 28 days with the same inspecting organisation. From 1 November 2026 most light vehicles move to a two-yearly cycle.

A Warrant of Fitness records that a vehicle met a national safety standard on the day it was inspected. That is all it does, and understanding the limits of that sentence saves people a great deal of money — both the buyers who treat a current warrant as proof of a sound car, and the owners who assume a fresh warrant means nothing will go wrong for a year.

Everything else about the system is administrative: how often you need one, what happens when a vehicle fails, and how a lapsed warrant quietly blocks your rego.

How often you need one

Frequency depends on the vehicle's age and, from late 2026, on when it was first registered. Under the rules in force until 1 November 2026, most light vehicles between four and fourteen years old are inspected annually, vehicles first registered before 1 January 2000 are inspected every six months, and a new light vehicle's second warrant falls due at three years.

That is about to change for a large share of the fleet. From 1 November 2026 most light vehicles first registered on or after 1 November 2019 move to a two-yearly inspection, new vehicles get their second warrant at four years instead of three, and pre-2000 vehicles move from six-monthly to annual. The bands are specific and the registration dates matter, so the November 2026 changes are worth reading against your own vehicle rather than assumed from a summary.

If you simply want to know when yours is due, NZTA publishes an expiry lookup and how to check your WoF expiry explains what it can and cannot tell you.

What the inspection covers

The inspection works through the safety systems: tyres and wheels, brakes, steering and suspension, structure and rust, lights and indicators, glazing, wipers and washers, doors, seatbelts, airbags, the exhaust and fuel systems, and the vehicle's built-in warning systems. From 1 November 2026 the warning lights for autonomous emergency braking and lane keep assist are added to that list for vehicles fitted with them.

It does not cover mechanical condition, service history, or anything about how the vehicle will behave next month. What is checked and what is not goes through the scope properly, including the separate rules for caravans, trailers and motorhomes, which are certified in their own right rather than under the towing vehicle's warrant.

There is no grace period for an expired WoF or an expired rego. The infringement fee is $200 for each. The day after the expiry date the vehicle is unwarranted, and no rule gives you a week to sort it out.

When something goes wrong

Three situations account for most of the trouble, and each has its own answer.

The vehicle failed. This is not a penalty. You have 28 days from the failed inspection for a free recheck, it must be with the same inspecting organisation — a different branch of the same company is fine — and after 28 days you pay for a fresh inspection. What to do after a failed WoF covers the recheck rules, including the trap where a repaired system has to be performance-tested again.

The warrant has expired. You may drive the vehicle only to take it for repair or to obtain a new warrant, and only if it is safe to do so. That exception is narrow and it is the only one. The rules on driving with an expired WoF set out what that covers, what it does not, and what happens to your insurance position.

Your rego is blocked because of it. A vehicle licence cannot be renewed without a current warrant, which produces a circle that looks unsolvable: no rego without a WoF, and no legal driving without a rego. The way out of the rego and WoF deadlock is the same legal exception, plus an honest account of the risk it does not remove.

Cost, and where it is not the number you think

WoF pricing is not regulated, so it varies between providers and it is legitimate to ring around. What that comparison usually misses is the recheck: because the free recheck ties you to the organisation that inspected the vehicle, a cheap inspection a long drive away becomes an expensive one the moment something fails. What a WoF costs sets out what you are actually paying for and which quotes are not comparable.

If it turns out you need a CoF instead

Not every vehicle takes a warrant. Heavy vehicles, vehicles that carry paying passengers, and rental vehicles are certified with a Certificate of Fitness on a shorter cycle, and the category is decided by weight and by use. Since use changes the day you start hiring a vehicle out or driving people for money, working out whether you need a WoF or a CoF is worth doing before the use changes rather than after.

Frequently asked questions

How often do I need a WoF?

Until 1 November 2026, most light vehicles between four and fourteen years old need one every year, vehicles first registered before 1 January 2000 need one every six months, and a new light vehicle's next warrant falls due at three years. From 1 November 2026 those bands change substantially, with most of that middle group moving to a two-yearly inspection and pre-2000 vehicles moving from six-monthly to annual.

What does a WoF actually check?

It is a safety inspection against a national standard: tyres and wheels, brakes, lights, steering and suspension, structure and rust, glazing and visibility, seatbelts, doors, and the warning systems the vehicle was built with. It is not a mechanical inspection. It says nothing about whether the engine is sound, the clutch will last or the vehicle is worth buying.

Can I drive without a current WoF?

Only to take the vehicle for repair or to obtain a new WoF, and only if it is safe to drive. That single exception is the whole allowance. Any other use of an unwarranted vehicle on the road exposes you to a $200 infringement fee, and there is no grace period after the expiry date.

Does a WoF mean the car is in good condition?

No, and this is the most expensive misunderstanding in the whole system. A warrant records that the vehicle met the safety standard at the moment it was inspected. It is not a warranty, it does not cover mechanical condition, and it is not a substitute for a pre-purchase inspection when you are buying.

Where can I get a WoF done?

At any inspecting organisation appointed by NZTA — that includes testing stations, AA centres that do inspections, and a large number of independent garages. The standard is national, so no provider is stricter or softer by design. Price is not regulated, so that does vary.
