Traffic volumes on State Highway 59 and State Highway 58 between Paremata and Pāuatahanui have changed since Transmission Gully Motorway - Te Aranui o Te Rangihaeata opened. Waka Kotahi is looking at the function of these roads and what each corridor could look like in future.
Waka Kotahi NZ Transport Agency is considering options for the future of State Highway 59 (old SH1 between Mackays Crossing and Linden) and State Highway 58 (between Paremata and Pāuatahanui).
This process involves looking at how the roads will be used henceforth and by whom; what the transport network impacts are likely to be from increased land development and changes in population; changes in traffic volumes and speeds since the opening of the Transmission Gully Motorway - Te Aranui o Te Rangihaeata; and what changes could be made to the roads to meet the needs of those who use them.
In early 2023, we consulted with five key stakeholder groups – Porirua City Council, Greater Wellington Regional Council, Paremata Residents’ Association, Plimmerton Residents’ Association and Ngāti Toa Rangitira – on SH59 from Paremata to Plimmerton. This was part of a Board of Inquiry consent condition following the completion of the Transmission Gully Motorway - Te Aranui o Te Rangihaeata. Our consultation report outlines the process for the consultation, what the stakeholders said in their submissions and our responses to this feedback.

Submissions were received from all stakeholder groups and are available below. Note: some of the information in these submissions is redacted to protect the privacy of the submitters.
The feedback we received from this consultation will input into the development of a Strategic Plan for the full extent of the SH59 corridor which will have a longer-term view of how that section of road is used (as well as consider future growth projects and local issues such as increased housing and population changes).
Wider consultation with the community and further stakeholder groups will be carried out further down the track and feedback from this will also be considered in the development of the Strategic Plan.
This plan will firstly consider the function (how the road is used and by whom) of SH59 section by section. For example, the function of SH59 along the Mana Esplanade differs from its function to the south. Once function has been confirmed, we will develop preferred options for the future form of the road (appropriate to each section of SH59). These option preferences will then be considered for future funding.
The plan will inform future National Land Transport Plans.
Another consent requirement was to determine the effects of reduced traffic and potentially higher environmental speeds on the coastal route resulting from the opening of the Transmission Gully Motorway – Te Aranui o Te Rangihaeata. The findings confirmed that no new safety risks have been introduced due to that motorway becoming operational.
