The VTNZ has refused my daughter a warrant because they say her fuel cap is not safe, and could leak.
On checking it , it appears just fine. They are telling her to replace it with a new one. Is this the latest thing with VTNZ that having a blitz on or just someone being over picky.

While there will always be interpretations of the rules by the different authorised NZTA inspectors, they must be able to justify their decisions to pass or reject a vehicle.

The rules would appear to be very clear in regards to the fuel cap.

The reasons for rejection on a fuel system are listed below.

Condition

1. There is a noticeable fuel leak from the fuel system.
2. The security of the fuel tank is affected by:
a) corrosion damage, or
b) cracking or other damage, or
c) insecure or loose tank mountings.
3. A fuel line is insecure or loose so that it is likely to be damaged during normal use of the vehicle.
4. A fuel pipe is severely damaged or excessively corroded.
5. A fuel hose is damaged or perished.
6. The fuel pump is insecure.
7. The fuel filler cap or capless fuel filler seal is missing, insecure or likely to allow fuel spillage when the vehicle is in normal use.
8. The fuel tank is fitted with a ‘temporary use’ fuel filler cap

If you disagree with the rejection you are entitle to take the car back and ask for the inspector or their Manager to justify their decision.
