On 20 April 2012, the NZ Transport Agency lodged its regulatory consents application for the Mackays to Peka Peka project with the Environmental Protection Authority (EPA).
The NZ Transport Agency application sought approval to construct approximately 16 kilometres of expressway from just north of Mackays Crossing to Peka Peka Road following the designation set aside for the Western Link Road. The Expressway will pass through Raumati, Paraparaumu and Waikanae between the existing state highway and the coast.
The Mackays to Peka Peka route is an important component of the Wellington Northern Corridor which runs from Wellington Airport to north of Levin.
The Wellington Northern Corridor is one of seven ‘roads of national significance’ that the Government has identified as essential state highways which require upgrading to reduce congestion, improve safety and support economic growth in New Zealand.
