Weigh right programme

The nation-wide Weigh Right Programme is designed to reduce heavy vehicle overloading on New Zealand roads. It will also help improve productivity and safety, while ensuring heavy vehicle operators pay their fair share of road maintenance.

The programme will see the installation of roadside technology and the development of intelligent software to direct potentially overloaded vehicles into 12 weigh stations throughout New Zealand. To do this, four existing weigh stations are being upgraded and an additional eight will be built at new sites.

This network will cover almost half of all New Zealand’s freight kilometres travelled. The national sites are:

  • Marsden in Northland
  • Three locations in the Auckland region (North Shore, Stanley St and Bombay)
  • Tauranga Port
  • Paengaroa (Bay of Plenty)
  • Taupō
  • Napier
  • Ohakea (Manawatū)
  • Mackays Crossing (Wellington)
  • Rakaia (Mid Canterbury) and
  • Glasnevin (North Canterbury).

The sites have been selected based on heavy vehicle volumes and risk profile. The highest volume sites are close to major centres, ports or significant highway junctions. These sites cover almost half of New Zealand’s freight kilometres travelled.

By addressing the impacts of heavy vehicle overloading, the Weigh Right Programme will contribute to increased productivity for compliant operators through fewer weigh station stops. It will also support a level playing field across the commercial heavy vehicle industry.

Currently, competitors who are illegally overloading can unfairly disadvantage compliant operators. Heavy vehicle safety will also improve by reducing the risk of rollovers from overloading.

To support weight compliance, the programme is building a new easy-to-use heavy vehicle permits system.
