Each project generally progresses through several phases, which can take several years. These pages set out the general planning phases for each project.

The process can begin with the identification of a corridor study area. After technical investigations and engagement with stakeholders, property owners and the community, the process continues to route protection and Notices of Requirement.

Notices of Requirement process

The route protection stage provides landowners with certainty as to whether their property is impacted.

Note that Te Tupu Ngātahi is responsible for the planning phases of the project only. Timelines for funding and delivery mechanisms for future phases including construction are yet to be confirmed.

What is a corridor study area?

A corridor study area is the area of land identified for where a new future transport project could be located. The study areas are typically much wider than the final requirements for that of a new transport route.

Once a study area has been identified, we need to undertake detailed investigations before we can start to narrow down the area and understand the impacts on any individual properties.

Part of these investigations include meeting with property owners to understand how they use the land and any other characteristics or issues we should be aware of (e.g if the land is used for a specific purpose, any special features of the land).

We also need to understand the environmental effects, such as possible ecological, noise or visual impacts. We look at how these can be avoided, minimised or mitigated. We may need to undertake non-intrusive site walkovers to do this and if this needs to occur, we’ll seek the permission of landowners first.

Corridor study areas

It is generally expected that the new routes will be located somewhere within the study area, unless detailed investigations, including geotechnical studies, necessitate changes. Factors that will be considered when locating the transport route include:

  • Environmental (e.g significant ecological areas, watercourses and wetlands)
  • Topography
  • Stormwater treatment
  • Connections to existing transport network
  • Road geometry and transport corridor facilities
  • Land ownership
  • Legal requirements

What happens next?

Once the corridor study area has been refined, a preferred route is submitted as part of a Detailed Business Case to Auckland Transport and Waka Kotahi NZ Transport Agency for approval.

Following endorsement, the projects proceed to the route protection phase.
