What to Do if Your Car Fails Its WoF

A failed Warrant of Fitness is not unusual and it is not the end of the world. Thousands of vehicles fail their WoF inspections in New Zealand every week, often for relatively minor and inexpensive issues. The important thing is to understand the process, get the repairs done promptly, and get your vehicle re-inspected so you can legally drive again.

What Happens When You Fail?

When your vehicle fails its WoF, the testing station will give you a detailed inspection report listing every item that did not pass. Each failed item will be clearly described, and the inspector may also note advisory items — things that are not yet failures but will likely need attention soon.

If your WoF was still current when you took the vehicle in for inspection, your existing WoF remains valid until its original expiry date. This means you can still legally drive the vehicle while you arrange repairs, provided the current WoF has not yet expired. If your WoF has already expired, you should not drive the vehicle on public roads until it passes re-inspection.

Repair Timeframe

After a failed WoF inspection, you have 28 days to get the repairs completed and bring the vehicle back for a re-inspection at the same testing station. If you return within this 28-day window, the re-inspection is limited to the failed items only, which is quicker and often cheaper. If you exceed the 28-day period, you will need a full new WoF inspection, which means paying the full inspection fee again.

The Re-Inspection Process

When you return within 28 days, the inspector will only check the items that previously failed. If everything passes, you receive your new WoF sticker. Many testing stations offer free or low-cost re-inspections if the repairs were carried out at their own workshop — it is worth asking about this when you first receive the fail report.

If some items pass but others still fail, the 28-day clock does not reset. You will need to fix the remaining items and return again within the original 28-day period.

Common WoF Fail Items

Some items come up far more frequently than others. The most common reasons for a WoF failure in New Zealand include:

• Tyres — insufficient tread depth (below 1.5mm), damage, or incorrect size. Replacing tyres costs $80 to $250 each depending on the size and brand.
• Lighting — blown bulbs, cracked lenses, or misaligned headlights. Bulb replacement is usually under $30, but headlight realignment can cost $50 to $100.
• Windscreen damage — chips or cracks in the driver's line of sight. A chip repair costs around $60 to $100, while a full windscreen replacement can be $300 to $600+.
• Brake wear — worn pads, scored discs, or low brake fluid. Brake pad replacement costs $200 to $500 per axle.
• Suspension components — worn bushings, ball joints, or shock absorbers. Costs vary widely from $100 to $800+ depending on the part and vehicle.
• Exhaust leaks or emissions — a leaking exhaust can cost $100 to $500 to repair depending on the location and severity.
• Structural rust — significant rust on structural components can be expensive to repair and in severe cases may make the vehicle uneconomical to fix.
• Seatbelt issues — frayed or non-retracting belts. Replacement costs $100 to $300 per belt.

Cost of WoF Repairs

The cost of getting your vehicle up to standard depends entirely on what failed. Simple items like a blown bulb might cost under $20 to fix, while a combination of worn brakes, tyres, and suspension work could easily run to $1,000 or more. If you are unsure whether the repairs are worth the cost, get a second opinion from another mechanic before committing — especially for older vehicles where the repair cost may approach or exceed the car's value.

Can You Drive Without a WoF?

Driving without a current WoF is illegal in New Zealand. If stopped by police, you face an instant fine of $200. Your vehicle can also be issued a notice to repair or, in serious cases, ordered off the road entirely. Beyond the legal consequences, driving a vehicle that has failed its safety inspection puts you, your passengers, and other road users at risk.

There is one exception: you are permitted to drive directly to a testing station or a repair workshop for the purpose of getting the vehicle repaired and re-inspected, even if the WoF has expired. However, this is limited to direct travel only — no detours.
