Contract awarded for Transmission Gully
Media release,

Purpose

The NZ Transport Agency applications sought approval to construct 27 kilometres of inland highway through Transmission Gully linking MacKays Crossing in the north with Linden in the south. Transmission Gully is so named because it generally follows the route of the Paekakariki–Takapu Road 110 kV line.

Benefits

All of these applications were lodged under the new national consenting process through the Environmental Protection Authority (EPA).

The EPA was set up as part of a governmental move to streamline and simplify the resource consent application process. One of the benefits of the EPA process is the shorter timeframe for considering applications which, therefore, allows outcomes to be known much more quickly than previously. The entire consenting process, using the EPA path, has taken less than a year.

  • Working together

    The New Zealand Transport Agency, together with the Porirua City Council (PCC) and Transpower New Zealand Limited lodged Notice of Requirement and resource consent applications for the Transmission Gully Proposal comprising:

    • the Main Alignment (proposed new highway) and the Kenepuru Link Road for which applications were made by the NZ Transport Agency for notices of requirement for new designations and resource consents;
    • Two Link Roads that will connect the Main Alignment with the suburbs of Whitby and Waitangirua for which applications were made by the Porirua City Council for notices of requirement for new designations and resource consents; and
    • The relocation of 24 transmission towers and strengthening of 10 towers required in order to accommodate the Main Alignment for which applications were made by Transpower New Zealand Limited.

    The three applicants presented integrated application documents.
