Transmission Gully motorway project before the Public Private Partnership

On this page you'll find information about the Transmission Gully motorway project, before the Public Private Partnership (PPP) was signed.

For all information on the design and construction of the Transmission Gully motorway by the Public Private Partnership consortium (Wellington Gateway Partnership), please go to the Transmission Gully motorway project page.

 

Chronological timeline

There’s been documented public interest in an inland route through Transmission Gully going back as far as 1919. However, it has only been in the last two decades that public views have been canvassed more formally.

In 2008, two major public consultations were undertaken to ask residents of the greater Wellington region if a route through Transmission Gully should be progressed. Both public consultations returned overwhelming support for a motorway through the gully.

In the first half of 2012, regulatory consent applications for the project were heard and approved by an independent Board of Inquiry. And in November 2012, Waka Kotahi NZ Transport Agency received the Government’s approval to proceed with the Transmission Gully motorway through a Public Private Partnership.

  • 2008

    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.

  • 2010

    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, Waka Kotahi lodged a request with the EPA seeking changes to the Wellington Regional Freshwater Plan to provide a clearer policy framework within which resource consent applications for the Transmission Gully project for activities in and on water bodies could be considered.

    A series of Open Days and a Project Expo were held in October 2010 to give the public the opportunity to find out more about the Transmission Gully project. The Open Days and Project Expo covered the planning process, noise issues, traffic effects, ecology and water issues, and showed what the Transmission Gully route will look like.

  • 2012

    The Board of Inquiry’s hearing on the Transmission Gully applications was conducted from 13 February 2012 to 15 March 2012.

    On 22 June 2012, the Board of Inquiry released its final decision on the Transmission Gully applications.

    In August 2012, the Minister of Transport directed Waka Kotahi to assess the suitability of using a Public Private Partnership (PPP) procurement model to design and build the motorway.

    Following an extensive business case analysis (using the Treasury’s better business case framework), Waka Kotahi determined that the project meets the Treasury’s criteria for a PPP procurement model.

    In November 2012, the Cabinet gave Waka Kotahi approval to finance and build the Transmission Gully motorway using a PPP. Waka Kotahi 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 was confirmed by the Cabinet before Waka Kotahi awarded the PPP contract in 2014.

  • 2013

    In January 2013, Waka Kotahi called for ‘Expressions 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, Waka Kotahi announced the two consortia that had been shortlisted to deliver the Transmission Gully Public Private Partnership (PPP) project. These were the Wellington Gateway Partnership and the Positive Connection consortia.  A ‘Request for Proposal’ (RFP) was issued to the two shortlisted consortia and their subsequent proposals underwent a rigorous evaluation process to select the preferred bidder for the project.

    In December 2013, Waka Kotahi announced the Wellington Gateway Partnership as the preferred bidder to finance, design, build, operate and maintain the Transmission Gully motorway.

  • 2014

    In July 2014, Waka Kotahi signed a Public Private Partnership  (PPP) contract with the Wellington Gateway Partnership.  Under the terms of the PPP contract, the Wellington Gateway Partnership will design, construct, finance, operate and maintain the new Transmission Gully motorway for the 25 years that will follow the expected five-year period to build the motorway. The motorway is scheduled to open for traffic in 2020.

Transmission Gully applications to the Environmental Protection Authority (EPA)

In August 2011, Waka Kotahi NZ Transport Agency applied for designation and resource consents for the Transmission Gully section of the Wellington Northern Corridor road of national significance project (Levin to Wellington Airport).

The Waka Kotahi applications sought approval to construct 27 kilometres of inland motorway through Transmission Gully linking Mackays Crossing in the north with Linden in the south. Transmission Gully is so named because it generally follows the route of the Paekakariki–Takapu Road 110 kV electricity transmission line.

All of these applications were lodged under the new national consenting process through the Environmental Protection Authority (EPA), and heard through a Board of Inquiry.

The EPA was set up as part of a governmental move to streamline and simplify the resource consent application process. One of the benefits of the EPA process is the shorter time frame for considering applications, which, therefore, allows outcomes to be known much more quickly than previously. The entire consenting process, using the EPA path, took less than a year.
