Overview

At Waka Kotahi NZ Transport Agency, we’re aiming for a road system free of death and serious injury. We also want to enable a productive land transport system, which supports a level playing field for the heavy vehicle industry. The Weigh Right Programme is one way we are delivering this.

In the programme, roadside technology is installed and intelligent software developed to screen heavy vehicles and to direct potentially overweight vehicles into a commercial vehicle safety centre (CVSC, formerly weigh station) for further inspection.

Vehicle screening involves weigh-in-motion or in-road scales, automatic number plate recognition cameras and electronic signs all working together to identify potentially overweight vehicles.

Targeting potentially overweight non-compliant vehicles can enable compliant heavy vehicles to continue their journey without interruption, and makes for a better use of resources and time.

It’s about safer roads, a level playing field for industry and smarter regulation.

Scope

Twelve CVSC sites will be rolled out in the Weigh Right Programme. The weigh station at Glasnevin (north Canterbury) was upgraded and opened in January 2019 and the one at Paengaroa (Bay of Plenty) was opened in July 2020.

The locations of the CVSCs are on heavy-volume routes and cover 46% of the total freight kilometres travelled in New Zealand.

These sites are close to major centres, sea ports or significant highway junctions and at locations where it is difficult for heavy vehicles to avoid.
