Heavy vehicle permits

There are strict controls on the weight and axle loads of overweight vehicles.

Overdimension vehicles and loads need to follow additional requirements before travelling on our roads.

Specialist vehicles may require permitting based on their rear-axle mass limit.

The VDAM manual states Waka Kotahi NZ Transport Agency’s policies, standards, processes and procedures for the permitting of vehicles exceeding standard dimensions and mass limits. It also references Performance Based Standards (PBS) for non-standard vehicles.
