The NZ Transport Agency 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.
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.
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.
