Warrant of Fitness (WOF) in New Zealand: The Essentials

A Warrant of Fitness is the safety inspection that keeps light vehicles legal on New Zealand roads. It's separate from registration/rego — you need both current — but it's the one most people put off until the last minute. Here's what actually gets checked, how often, and what to do if yours has lapsed.

What is a WOF?

A WOF is a periodic safety inspection for cars, vans, and other light vehicles, confirming the vehicle meets minimum roadworthy standards. It's carried out by an authorised inspecting organisation and results in either a pass (WOF issued) or a list of items that need fixing before it can pass.

What gets checked in a WOF inspection

A standard WOF check covers safety-critical systems, generally including:

• Brakes (condition and performance)
• Steering and suspension
• Tyres (tread depth, condition, correct fitment)
• Lights, indicators, and reflectors
• Windscreen and wipers (visibility and damage)
• Seatbelts and structural condition
• Exhaust and structural rust/corrosion

It is a safety check, not a full mechanical service — a vehicle can pass its WOF and still have issues that aren't covered by the checklist. Regular servicing alongside your WOF schedule catches more than the WOF alone.

How often do you need a WOF?

Frequency depends on the vehicle's age and history:

• New vehicles are generally on a longer initial cycle before their first WOF is due.
• Older vehicles are typically inspected more frequently (commonly every six or twelve months, depending on age and current rules).
• Your exact due date is shown on your current WOF label and is checkable online against your plate.

Because the frequency schedule is set by vehicle age rules that are periodically reviewed, always check your specific due date rather than assuming based on a previous vehicle.

WOF vs Certificate of Fitness (CoF)

A Certificate of Fitness is the equivalent inspection for heavier vehicles — typically those over 3,500kg, plus buses, taxis, and some other vehicle classes used commercially. CoF inspections are generally more frequent and more detailed than a WOF. If you're unsure which applies to your vehicle, check its vehicle class on your registration details or ask a compliance specialist.

What happens if your WOF expires

An expired WOF means the vehicle isn't legal to drive on public roads, and it also blocks you from relicensing (renewing rego) until a new WOF is issued. If your WOF has lapsed:

• Don't drive the vehicle on public roads to get it inspected — arrange alternative transport or a mobile/at-location inspection if available.
• Book a re-inspection as soon as possible; a lapsed WOF doesn't require starting registration over, just a fresh pass.
• If the vehicle fails, you'll get a list of required repairs — some inspecting stations offer a discounted re-check within a short window once repairs are done.

Frequently asked questions

Can I drive with an expired WOF to get it checked?

No. Driving with an expired WOF on public roads is not legal, even if your destination is the inspection station. Arrange transport instead.

Does a new car need a WOF straight away?

New vehicles are generally on an extended initial cycle before their first WOF is due — check your specific vehicle's due date rather than assuming, since rules are periodically updated.

What's the difference between a WOF fail and a "minor defect"?

Inspecting stations typically flag issues by severity — some minor items may not fail the inspection outright but are noted for attention, while safety-critical faults result in a fail until repaired and re-checked.

Do electric vehicles need a WOF?

Yes — EVs are still light vehicles and go through the same WOF process, with some inspection points adapted for electric drivetrains rather than internal combustion.
