Blue slip NSW: when you need an AUVIS inspection
A NSW blue slip (AUVIS inspection) is required when registration has lapsed three months or more, the vehicle comes from interstate or overseas, it has no plates, or it is an approved written-off vehicle being re-registered. The report is valid for 42 days from inspection.
When you need one
- Registration has been lapsed for three months or more
- The vehicle is arriving from interstate or overseas
- The vehicle has no number plates
- The vehicle is an approved written-off vehicle being re-registered
Blue slip vs pink slip
A pink slip is an eSafety check — a periodic roadworthiness inspection for a vehicle already registered. A blue slip goes considerably deeper: it verifies vehicle identity (VIN and engine numbers), roadworthiness and design compliance. It is an identity and compliance check, not just a safety check.
The 42-day window
An AUVIS report is valid for 42 days from inspection. That sounds generous until a modification issue surfaces and you need engineering certification before the vehicle will pass. Sequence the work: certify significant modifications first, then book the blue slip.
You still need CTP
A blue slip does not register the vehicle. You will also need CTP (green slip) insurance to complete NSW registration.
