Haere mai! Welcome

Faster and more reliable state highway journeys to drive economic growth

The SH1 Wellington Improvements Roads of National Significance project will alleviate Wellington’s longstanding bottlenecks with the construction of a second Terrace Tunnel, a second Mt Victoria Tunnel, and a major roading upgrade at the Basin Reserve, and supporting improvements to the state highway corridor through Wellington city, Hataitai and Kilbirnie. People and businesses will be able to get where they need to go faster and more reliably, while unlocking productivity and regional economic growth.

Congestion on SH1 through the city has a long history, with solutions looked at a number of times. In developing the proposed design, we have canvassed these previous investigations and previous community feedback and made refinements to align with the Government Policy Statement on land transport 2024 and the investment objective endorsed by the NZTA Board in October 2024.

We're now inviting further feedback from our stakeholders and the community.

Community engagement

This engagement survey is open until 11:59pm Sunday 14 December 2025.

We’ll publish a summary of what we heard from the community in February next year and consider your feedback as we continue to refine the project design.

The survey will take between 3 and 15 minutes depending on how much feedback you wish to provide. We will be asking you to tell us:

  • A brief bit about yourself and your travel along the SH1 route
  • Your perceptions on the benefits of the SH1 Wellington Improvements project
  • Your perceptions on particular aspects in sections of the improvements (you can select as many sections to view as you wish or none at all)
  • Your perceptions on how much difference the SH1 Wellington Improvements project will make to you and to the wider Wellington region

You will also be able to expand on your responses and provide comments in open text sections throughout the survey.

The engagement brochure containing more detailed information is available at: https://www.nzta.govt.nz/projects/sh1-wellington-improvements/community-engagement

The link will open in a separate tab on your browser so you can keep the survey open while looking at the project webpage.

Thank you, we appreciate your time.
