SH1 Templeton to Dawsons Road permanent speed limits

Section menu

Project introduction

Waka Kotahi NZ Transport Agency has set a new permanent speed limit for the short section of State Highway 1 (SH1) from Templeton to Dawsons Road, just south of Christchurch.

  • Project type

    Speed review
  • Project status



Between December 2020 and February 2021, Waka Kotahi consulted with local community, iwi, businesses and stakeholders on a proposed lower speed limit for the stretch of State Highway 1 (SH1) from Templeton to Dawsons Road.

Significant changes have occurred at this location, including a new roundabout, which has changed the driving environment. This has meant the former speed limit of 100km/h is no longer right for the road. With construction of the Christchurch Southern Motorway stage 2 project nearly complete and the new Dawsons Road Roundabout fully functioning, the safer speed limit of 80km/h is a logical fit for the new road layout.

What we know

South and southwest Christchurch has seen significant growth over the past 10 years. A lower speed was needed to future-proof the road for increased traffic demand and to create a logical reduction in speed as drivers exit the new Christchurch Southern Motorway.

Due to motorway construction, this section of road has had temporary speed limits in place for a couple of years now. The lower speed limit will help regulate the speed of traffic travelling off the new motorway into the Templeton township and create consistency with speed limits on side roads.

In addition to a lower speed limit, diagonal markings on the edge of the road will be repainted and extended as a traffic calming technique to visually narrow the road, signalling that drivers need to slow down. The existing passing lane will remain in place and will be monitored by Waka Kotahi and local police for speed compliance, speeds while overtaking, and the number of passing vehicles.

Speed increases the likelihood of crashes and the severity of crashes when they happen. A small reduction in speed can make a big difference in improving safety on our roads.

Consultation and submissions

Public consultation on the project was open for six weeks from 16 December 2020 to 1 February 2021.

As the consultation coincided with the holidays, we extended the feedback period from four to six weeks, to ensure everyone has a chance to have their say.

We received 58 submissions from stakeholder organisations and the public.
