Waka Kotahi NZ Transport Agency sought public input into proposals to set permanent new speed limits for State Highway 1 and State Highway 59, and local link roads connected to Transmission Gully. Based on the feedback received during consultation, new speed limits are now in operation.
Speed limits are one way of keeping people safe on the roads. They can also help ensure that the roads are flowing smoothly and connecting well with other parts of the roading network.
Waka Kotahi and Porirua City Council sought feedback on the proposed speed limits for those parts of SH1 and SH59 that have been realigned or built as part of the motorway construction, motorway on and off-ramps, and the new Porirua link roads.
Before speed limits can be confirmed, formal consultation on the new speed limit proposals is required under the Land Transport Rule: Setting of Speed Limits 2017.

Waka Kotahi is introducing a variable speed limit (VSL) to safely manage southbound traffic where SH1 and SH59 merge, and to ensure safety and efficiency on the section of SH1 to the Helston Road overbridge at Johnsonville.
This extends the existing VSL, currently in place on SH1 from Helston Road to the Terrace Tunnel, to the southern end of Transmission Gully.
A VSL allows Waka Kotahi to adjust the speed limit and help manage incidents on the road or adverse weather conditions that may affect safety of road users. It can also be used to slow vehicles down if there is congestion ahead, or for temporary traffic control.
Electronic VSL signs will be progressively installed, however Waka Kotahi will temporarily use static signs approaching the Linden merge point between SH1 and SH59 until it is comfortable with how the network surrounding Transmission Gully is working.
All other speed limits that were consulted on are to ensure that vehicles are travelling at safe and appropriate speeds when using on and off-ramps connected to the motorway and other sections of state highway.
On 28 June 2021, Waka Kotahi consulted on proposed speed limits for parts of SH1 and SH59. Consultation was open for four weeks and closed on 27 July 2021.
During consultation we received 34 submissions from private individuals, road user groups and community organisations. We appreciate the response from the community and thank everyone who provided feedback.
The submissions did not identify any issues that Waka Kotahi had not already considered.
