The City Centre to Māngere (CC2M) mass transit corridor is a key component of Auckland’s future transport network.

The CC2M project was prioritised through the Auckland Transport Alignment Project 2018 for the 2018-2028 decade.

In 2018, the New Zealand Transport Agency (NZTA) commenced preparation of an indicative business case for the project.

In April 2018, NZ Infra (a joint venture of the New Zealand Superannuation Fund and Canadian institutional investors CDPQ Infra), submitted an option for an alternative delivery and financing approach to the CC2M Project.

Neither of these options is fully developed, and therefore the Government has asked the Ministry of Transport to run a process with both NZTA and NZ Infra where they further develop their separate options for Auckland’s rapid transit project.

Both parties have agreed to take part in this process and have received a set of requirements.  These requirements include commercial and financial matters, the technical solution and service delivery response, and how their solution will achieve the key goals for the project. 

This process will take up to six months, and at its completion, the intent is that the Government will be in a position to determine which delivery partner will provide the best long-term outcomes and value for money for Aucklanders and for New Zealand.

The objectives of the project

The Government has agreed the following objectives for the project:

Access and Integration

  • Improved access to employment, education and other opportunities through enhancing Auckland’s Rapid Transit Network and integration with Auckland’s current and future transport network.


  • Optimised environmental quality and embedded sustainable practices.

Urban and Community

  • Enabling of quality integrated urban communities, especially around Māngere, Onehunga and Mt Roskill.

Customer Experience

  • A high-quality service that is attractive to users, with high levels of patronage.

Why is light rail needed for Auckland?  

Congestion in Auckland costs hundreds of millions in lost productivity annually as the city grows by 40,000 people per year adding an additional 10,000 – 12,000 cars on the roads. Attractive public transport alternatives are needed to carry large volumes of people efficiently.

While public transport trips have now hit 100 million per year, light rail will carry an additional 11,000 commuters per hour and will service the growing employment areas of the city centre and Auckland airport which has 35,000 workers alone. Additionally, light rail will drive urban regeneration along its route from the city to Māngere.

What is happening in the next stage of the project?

Both NZ Infra and NZTA will progress their options for the CC2M corridor. The Ministry of Transport will support this process. 

This process will take up to six months and the Ministry of Transport will provide advice to the Government in February 2020.

How is the project being managed?

There is a Ministers’ Oversight Group comprising the Ministers of Finance, Transport and Urban Development, Environment, Infrastructure and Associate Transport.

A Chief Executive Advisory Group has also been set up to support the Secretary of Transport in his role in managing the process. This Group comprises Chief Executives Chaired by Peter Mersi. 


Background information

NZTA work to date

In May 2018 the NZTA was appointed the lead agency for delivering light rail in Auckland and has been developing a business case for the project based on work completed through the Auckland Transport Alignment process. This process is consistent with NZTA’s usual infrastructure investment approach.

This model would see NZTA lead the work to plan, design, construct, fund and maintain a light rail line from the city centre to the growing employment centre at Auckland Airport, providing capacity for 11,000 commuters per hour and driving urban regeneration along the route.

Over the last year NZTA has been developing an enhanced proposal for integrating light rail into the transport network. It is now looking to further advance its approach.

There are a number of options for funding the project, including a public-private partnership and looking at new revenue sources such as land value capture and third-party contributions. NZTA will explore these further in the next stage of the project.

About NZ Infra

NZ Infra is a joint venture of the New Zealand Superannuation Fund and CDPQ Infra (an infrastructure subsidiary of the Canadian pension fund, Caisse de dépôt et placement du Québec (CDPQ)).

CDPQ Infra is currently constructing the Réseau express métropolitain, a new 67km light rail line in Montreal.  In April 2018, NZ Infra submitted an option for an alternative delivery and financing approach to the CC2M Project.

This new infrastructure solution in the New Zealand context would see NZ Infra design, finance, construct, own and operate light rail in Auckland.
