To protect the road network, the Vehicle Dimensions and Mass (VDAM) Rule 2016 specifies the legal weights and axle loads. If your vehicle exceeds these load limits, you need to apply for an overweight permit before you travel.

You need to apply for an overweight load permit before you travel if:

  • The maximum legal weight of your vehicle exceeds:
    • 44 tonnes
    • or 45 tonnes for 7 axle combinations with a minimum wheel base of 16.8m
    • or 46 tonnes for 8 axle combinations with a minimum wheel base of 17.4m
  • The weight on any individual axle of your vehicle exceeds the legal weight.
  • The vehicle weight exceeds the weight restriction posted on the road or bridge (refer to Table 1 and Table 2 below for current weight restrictions) of your route.

Travelling on State Highways and local roads

Contact NZTA(external link). They will liaise with Christchurch City Council to approve the Christchurch City Council road portion.

We require a minimum of five working days to process the application as it depends on the complexity of your route and the amount of assessment we need to do. 

If we need more time to process an application, you will be notified.
