In 2008, during Phase 1 of the Transmission Gully project, the NZ Transport Agency undertook public consultation on the preferred route through Transmission Gully. The consultation resulted in 88.6% of respondents supporting the preferred route.
In 2010, during Phase 2 of the project, engagement on design and environmental matters was undertaken with iwi, community groups, statutory agencies and territorial/local authority stakeholders in preparation for the lodgement of Notice of Requirement (NoR) and resource consent applications with the Environmental Protection Authority (EPA).
In September 2010, the Transport Agency lodged a request with the Environmental Protection Authority (EPA) seeking changes to the Wellington Regional Freshwater Plan to provide a clearer policy framework within which resource consent applications for activities in and on water bodies can be considered.
A Board of Inquiry hearing was held on the request in July 2011 and the Board announced its final decision on 10 October 2011. Details of the final decision can be accessed on http://www.epa.govt.nz/Resource-management/tgpc/Pages/Final-report-and-decision.aspx.
On 15 August 2011, the Transport Agency lodged the applications with the EPA and detailed information on the applications, process and timeframes can be obtained on www.nzta.govt.nz/projects/transmission-gully-application.
On 24 August 2011, the Environmental Protection Authority (EPA) recommended to the Minister for the Environment that the regulatory consent applications lodged for the Transmission Gully project be directed to a Board of Inquiry as a proposal of national significance. Information on this can be accessed on the EPA website.
On 16 September 2011, the Minister for the Environment directed that the applications be referred to a Board of Inquiry. The Ministerial direction can be accessed on http://www.epa.govt.nz/Resource-management/tg/Lodgement-and-Notification/Pages/Ministers-Direction.aspx.

The Board of Inquiry’s hearing on the Transmission Gully applications was conducted from 13 February 2012 to 15 March 2012.
The Board of Inquiry’s draft decision was released on 4 May 2012 and can be accessed on the EPA website.
On 22 June 2012, the Board of Inquiry released its final decision on the Transmission Gully applications. The Board’s decision can be accessed on http://www.epa.govt.nz/Resource-management/tg/Pages/Final-report-and-decision.aspx.
In August 2012, the Minister of Transport directed the Transport Agency to assess the suitability of using a Public-Private Partnership (PPP) procurement model to design and build the highway.
Following an extensive business case analysis (using the Treasury’s better business case framework), the Transport Agency determined that the project meets the Treasury’s criteria for a PPP procurement model.
In November 2012, the Cabinet gave the Transport Agency approval to finance and build the Transmission Gully highway using a PPP. The Transport Agency was also given approval to borrow up to the estimated costs of traditional procurement as part of the PPP. Final approval of the borrowing limit will be confirmed by the Cabinet before the Transport Agency awards the PPP contract.
In January 2013, the Transport Agency called for ‘Expression of Interest’ from consortia (New Zealand and overseas) interested in and capable of delivering the Transmission Gully Public Private Partnership (PPP) project.
In April 2013, the Transport Agency announced the two consortiums shortlisted to deliver the Transmission Gully Public Private Partnership (PPP) project. These were the Wellington Gateway Partnership and the Positive Connection consortiums. A request for proposal (RFP) was issued to the consortiums and their proposals underwent a rigorous evaluation process to select the preferred bidder for the project.
In December 2013, the Transport Agency announced the Wellington Gateway Partnership as the preferred bidder to finance, design, build, operate and maintain the Transmission Gully Public Private Partnership (PPP) motorway.
The Transport Agency is currently in Public Private Partnership (PPP) contract negotiations with the preferred bidder, the Wellington Gateway Partnership. It is hoped to reach completion of negotiations in the second half of 2014. Progress to date remains consistent with that timeframe and if the negotiations are concluded successfully, the PPP contract for the Transmission Gully project will be awarded to the preferred bidder. Construction is then likely to start shortly after the awarding of the contract - with the Transmission Gully highway expected to be open for traffic in 2020.
