The East West Link, part of the NZ$10.5 billion Roads of National Significance (RoNS) programme, will provide a new link on the north side of the Mangere Inlet between State Highway 20 (SH20) at Onehunga and State Highway 1 (SH1) at Mount Wellington in Auckland.

It is expected to include improvements on SH1 through to Princes Street in Otahuhu. The project is the main part of the broader East West Connections programme.

The Link and broader programme are also featured in the "Auckland Plan" which sets out how Auckland will change and grow over the next 30 years.

However in late 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).

The option proposed comprised:

- 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 drainange improvements.

Planning applications for this option were lodged to the Environmental Protection Authority in December 2016 to begin the Board of Inquiry (BOI) process. In November 2017 the BOI handed down its draft decision, approving the planning applications for the project.

On 23 January 2018, BOI issued its final decision confirming the designations and granting the resource consents for the East West Link project.

Under the original timeline, construction was expected to commence in 2018, with the project completed by 2025.

In April 2018, the project was included in the Auckland Transport Alignment Project's (ATAP) investment priorities, for the 2018-2028 decade.

The ATAP reports the Government is reviewing East West Link. While the exact form of this investment is not yet known, it will generally focus on addressing the most significant congestion and freight access problems in the area in a way that better optimises existing infrastructure. The ATAP has assumed approximately $800 million will be invested in this corridor, representing a reduction of around $950 million from the earlier proposal.

The Draft Transport Agency Investment Priorities (TAIP) confirms NZTA is reviewing the project to align it with the new priorities set out in the Government Policy Statement (GPS) on Land Transport. Notably as a result, the project is not included in the National Land Transport Programme 2018-21, which outlines the NZTA's planned activities over the three year period.
