The inspection fee does not include the cost of any necessary repairs.

Most garages offer a free re-check within 28 days if repairs are completed.

VTNZ provides inspections only, with no repair services, offering an unbiased assessment.

The WoF 28-day rule allows you to get a free re-inspection if your vehicle fails its Warrant of Fitness (WoF) test and is repaired within 28 calendar days.

Here’s how it works:

If your car fails the WoF, you have 28 days from the date of the inspection to fix the issues.

You can return to the same testing station for a free re-check.

If you return after 28 days, you will need to pay for a new full inspection.

Note - The vehicle must only be driven if it’s safe and roadworthy, and only for the purpose of getting repairs or re-inspection.

This rule helps reduce costs and gives vehicle owners time to make necessary repairs without paying twice.

Most Common WoF Failures (Ranked Most likely first)

Tyre Issues

Worn tread, bald spots, or uneven wear are among the top reasons for WoF failure.

Tread depth must be at least 1.5 mm across the tyre.

Light and Indicator Problems

Faulty or burnt-out bulbs, broken lenses, or poor electrical connections are very common.

Includes headlights, brake lights, indicators, and number plate lights.

Brake Deficiencies

Worn brake pads, leaky brake lines, or uneven braking performance are regularly detected.

Brakes are critical to safety and closely scrutinized.

Windscreen Wiper and Washer Malfunctions

Wipers that smear or don’t work, and washers that don’t spray properly, are frequent minor failures.

Easily fixable but often overlooked.

Structural Rust and Damage

Rust in key structural areas (e.g., chassis, suspension mounts) can compromise vehicle integrity.

More common in older vehicles or those exposed to coastal environments.

Seat Belt Problems

Damaged, frayed, or non-functional seat belts lead to immediate failure.

Less frequent than tyres or lights but a critical safety concern.

Exhaust Issues

Leaky or excessively noisy exhaust systems are less common but still a reason for failure.

Includes poor sealing, rusted pipes, or damaged mufflers.

Yes, a check engine light can cause your vehicle to fail a Warrant of Fitness (WoF) in New Zealand. 

While the light may sometimes appear for minor or non-urgent issues, it still indicates that the vehicle’s onboard diagnostics system has detected a fault.

Many drivers ignore the check engine light, assuming it's not serious.

However, any illuminated warning light on the dashboard is a valid reason for WoF failure, regardless of the severity of the issue.

The vehicle must be diagnosed and repaired to turn off the light before it can pass inspection.

Even if the issue isn't major, the light must not be on during the WoF assessment.

Legally, you cannot drive a vehicle on public roads without a valid WoF, except in very limited circumstances. Driving without a current WoF is an offence under New Zealand law and can result in:

A fine of $200 if caught driving without a WoF.

No insurance coverage if you’re involved in an accident while the WoF is expired.

Your vehicle being deemed unsafe or non-roadworthy.

Exceptions

You may drive without a WoF only to get the vehicle repaired or to a WoF inspection, provided:

The vehicle is safe to drive.

You go directly to or from the place of inspection or repair.

Summary

You should not drive at all once your WoF has expired, unless you're going straight to a repairer or testing station, and your car is in a roadworthy condition.

A typical Warrant of Fitness (WOF) inspection takes 30 to 60 minutes to complete.

Many inspection centres estimate the process will take around 40 minutes.

The actual time can vary depending on -

The condition of the vehicle

The workload or busyness of the inspection centre

Vehicles in good condition may pass more quickly, while those with issues may take longer for assessment.

Yes, a damaged windscreen can cause your vehicle to fail a Warrant of Fitness (WoF) in New Zealand. 

During the inspection -

The windscreen is closely examined for cracks, chips, or other damage.

If any damage is larger than 25 mm, or located within the critical vision area (directly in front of the driver), the vehicle will not pass the WoF.

Even small chips in this area may lead to failure if they affect visibility or safety.

Repairing or replacing the windscreen may be required before the WoF can be issued.

Usually yes — if it’s small and cosmetic.

Pass likely (OK) -

• Dent 5 mm deep or less
• 40 mm wide or less
• No sharp edges or cracks
• No rust

On roof/pillars but only a light ding (e.g., hail)

Fail risk (Not OK) -

• Deeper than 5 mm or wider than 40 mm
• Sharp edges, torn metal, or cracks
• Rust present

Damage on critical parts (chassis rails, sills, major seams)

Plain takeaway -

Small, shallow dents = usually fine. 

Big, sharp, rusty, or on key structure = likely fail. 

If unsure, ask the inspector to check against the WoF rules.
