Heavy Vehicles and Overweight Permits
Ngā Waka Nunui me Ngā Puka Whakaaetanga Taumaha

If you operate a heavy vehicle, here you'll find the requirements for vehicle size and weight so that you can fit on the road safely, not impede other traffic and avoid damage to roads and bridges.

Overweight Permits

There are strict controls on the weight and axle loads of overweight vehicles. This is to protect our road network and bridges. If your vehicle exceeds the load limits, you need to apply for an Overweight Permit before you travel. Applications are to be made to both NZTA (for State Highways) and the local council. 

How to apply

  1. Fill out the NZTA overweight vehicle permit application form
  2. Send to [email protected]

For more information visit the NZTA Overweight Permit web page.

Over dimension Permits

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

This is so they can travel on the road safely – for example, get around corners and fit under bridges. The maximum dimensions for vehicles are set out in Land Transport Rule: Vehicle Dimensions and Mass Rule 2016 (VDAM Rule).

Over dimension permits are issued by NZTA.

High Productivity Motor Vehicles (HPMV)

The vehicle configuration for full HPMV allows freight operators to carry increased payloads on parts of the network where bridges have been assessed/upgraded to carry heavier weights.

The maximum weight of an HPMV depends upon the vehicle configuration and the route capacity.

Apply for a HPMV permit and read more on the NZTA website.


50MAX vehicle combinations have nine axles (one more axle than conventional 44-tonne vehicle combinations), meaning the overall truck load is spread further and there is no additional wear on roads per tonne of freight. This means 50MAX gives operators an option to carry increased payloads on parts of the network that, while economically important to New Zealand, carry lower volumes of freight.

Apply for a 50MAX permit to exceed mass on the NZTA website.
