Applications to the Environmental Protection Authority (EPA)

The NZ Transport Agency (NZTA) applied for designation and resource consents for the Transmission Gully section of the Wellington Northern Corridor of national significance project (Levin to Wellington Airport) in August 2011.

About the project

The NZTA 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.

In combination with this application, the Porirua City Council (PCC) sought approval for two roads that will link the new highway with the urban areas of Whitby and Waitangirua. As part of the project, and in order to accommodate the new highway Transpower New Zealand Limited sought consent to reposition the transmission lines between State Highway 58 (SH58) and Mackays Crossing.

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.
