East West Link

Detailed Planning
East West Link

The East West Link will provide a new link on the north side of the Mangere Inlet between SH20 at Onehunga and SH1 at Mount Wellington in Auckland.

It is expected to include improvements on SH1 through to Princes Street in Otahuhu. 

The proposed project includes: 

  • a new four lane arterial road between SH20 at Onehunga and the SH1 at Mt Wellington Highway
  • widening of SH1 between Mt Wellington Highway and Princes Street
  • free flow ramp connections at the Neilson Street Interchange
  • a grade separated for the Great South Road and Sylvia Park Road intersection
  • pedestrian and cycling link between Mangere Bridge and Onehunga through to Sylvia Park Town Centre, and
  • local road, landscape and drainage improvements.


Dec 2016 Planning applications for this option were lodged to the Environmental Protection Authority to begin the Board of Inquiry (BOI) process.
Nov 2017 The BOI handed down its draft decision, approving the planning applications for the project.
Nov 2017 The newly elected NZ Government announced a NZ$1 billion reduction in scale of the project by adopting an alternate option to that proposed by the previous NZ Government. It is unclear what the claimed reduced scale of works will comprise. The circa NZ$1.85 billion option chosen by the previous NZ Government was based on the findings of the 2014 Indicative Business Case prepared by the New Zealand Transport Agency (NZTA) and Auckland Transport Authority (ATA).
Jan 2018 BOI issued its final decision confirming the designations and granting the resource consents for the East West Link project.
Mar 2021 The New Zealand Supreme Court dismissed two appeals against the East West Link, upholding the Board of Inquiry's decision to award the Resource Management Act approvals for the project. The project continues to be re-evaluated against the Government Policy Statement on land transport, which was updated in 2020. Should the re-evaluation outcomes be met, and no further appeals are brought against the project, Waka Kotahi NZ Transport Agency will reassess the designation and scope of consents currently granted before moving forward with the project.
Jul 2023 The National Party releases their plan to reintroduce the 'Roads of National Significance' program as part of election commitments for the forthcoming NZ election. East West Link is included.
Mar 2024 The New Zealand Government released its draft Government Policy Statement on land transport 2024-34 for public consultation, which includes the development of the East West Link as a Road of National Significance.
