About the Proposal

The New Zealand Transport Agency (NZTA) lodged an application for the East West Link Proposal with the Environmental Protection Authority (EPA) on 16 December 2016. The application is for two notices of requirement and 23 resource consents ('the matters').

The East West Link Proposal involves the construction of a new four lane arterial road connecting State Highway 20 (SH20) at the Neilson Street Interchange in Onehunga with State Highway 1 (SH1) in Mt Wellington. The proposed highway travels along the northern edge of the Mangere Inlet (Manukau Harbour), which is a heavily industrialised area. It also involves reclamation, and effectively creates a coastal causeway.

In addition to the proposed highway, the proposal includes new local road connections within the Onehunga and Penrose areas and new, or upgraded, cycle and pedestrian facilities.

The East West Link proposal comprises:

  • A new four lane arterial road between SH20 at the Neilson Street Interchange in Onehunga and the on and off-ramps on SH1 at Mt Wellington Highway;

  • SH1 widened in each direction between Mt Wellington Highway and Princes Street to increase capacity to allow connection to the Project. Several bridges will either be upgraded or widened to facilitate this;

  • Major upgrades to the Neilson Street Interchange to enable direct access between SH20 and EWL through free flow ramp connections in all directions;

  • A full pedestrian and cycling link between Māngere Bridge and Onehunga through to Sylvia Park Town Centre;

  • Local road improvements at Galway Street, Captain Springs Road, Hugo Johnston Drive and a new access road for the existing ports; and A grade separated intersection of Great South Road and Sylvia Park Roads to provide improved reliability and future resilience.

  • Landscape and recontour the coastal edge of Māngere Inlet to reflect the original foreshore which existed before extensive historic reclamation; and

  • Incorporate stormwater treatment wetlands located within new headlands on the foreshore of the Māngere Inlet.

In total, the matters lodged for the consenting and designation of the East West Link Proposal are:

  • Two Notices of Requirement

  • 23 Resource Consents
