UPDATE: 20 February, 2026 – Remember to have a say on South Island speed reviews

There is still time for people to have their say on proposed changes to speed limits on sections of state highways in Canterbury, Southland and on the West Coast (more detail in the earlier release in December).

So far, there have been 818 total submissions, from 766 contributors, on the targeted proposals across the affected areas that have been the subject of community concern.

Consultation on these changes is open until 5pm on 6 March 2026. People can view the various proposals and have their say in short surveys here.

22 January, 2026 – Consultation opens on South Island speed limit changes:

Public consultation is now open on proposed speed limit changes on sections of state highways in Canterbury, Southland and on the West Coast (see more in the December release below).

From today, people can view the various proposals and have their say in short surveys here. Feedback needs to be provided by 6 March 2026.

We encourage all those with an interest in these speed limits to have their say.

19 December, 2025 – Speed limit changes proposed:

Targeted speed limit changes are being proposed on state highways across the South Island after community concerns were raised about safety.

Next month, New Zealand Transport Agency Waka Kotahi (NZTA) will open public consultations for people to have their say on these proposed changes in Canterbury, on the West Coast and in Southland.

The proposed speed limit changes include the following:

• State Highway 1 (SH1) at both ends of Temuka, South Canterbury – northern section 70km/h to 50km/h, southern section 80km/h to 60km/h.
• SH1 south of Amberley (North Canterbury) – 80km/h to 60km/h.
• SH1 south of Rolleston (near Christchurch) – 100km/h to 80km/h.
• SH75 north of Halswell (Christchurch) – 60km/h to 50km/h.
• SH73 Kirwee and Sheffield (Central Canterbury) – 70km/h to 50km/h.
• SH67 and SH67A Westport south including Buller Bridge (West Coast) – 100km/h to 60km/h.
• SH7 at Blacks Point (West Coast) – 70km/h to 60km/h.
• Introduction of Intersection Speed Zones* on SH1 at Norwood and SH73 at Waddington (Central Canterbury), and SH6 at Five Rivers (Southland) – 100km/h to 100/60km/h variable.

*Intersection Speed Zones (ISZs) feature electronic signage that temporarily lower the speed limit when a vehicle approaches to turn from or onto a side road.

“These proposed changes are highly targeted, covering just 12 kilometres of the South Island’s 5000km state highway network, but they will make a real difference where it matters most,” says NZTA director of regional relationships for the central and lower South Island, James Caygill.

“We’re focused on saving lives and reducing serious injuries without adding unnecessary delays for drivers.”

Each proposal meets the requirements of the Government’s Setting of Speed Limits Rule 2024, which mandates six weeks of public consultation before decisions are finalised. New limits will become legally enforceable once signs are installed and uncovered.

NZTA’s targeted approach to state highway speed management under the 2024 Rule prioritises:

• Schools Variable Speed Limits (VSLs)
• ISZs for high-risk rural intersections
• Speed changes and new speed limits needed for projects and seasonal speed limits
• A small number of community requests that meet strict criteria.
