Project overview

Te Ara o Te Ata – Mt Messenger Bypass aims to deliver a much improved road safety, resilience and journey experience. The bypass is a new 6km route from Uruti to Ahititi that avoids the existing steep, narrow and winding route over Mt Messenger on State Highway 3.

It includes two bridges of approximately 125m and 30m length, and a 235m tunnel. The route will be lower and less steep than the existing road.

A substantial environmental restoration programme is also a key feature of the project.

Construction is underway and is expected to take approximately four years.

  • Partnering with Ngāti Tama

    Our relationship with Ngāti Tama began in 2016 when we approached them as manawhenua of the rohe surrounding the Mt Messenger section of SH3, to become involved in the project. Ngāti Tama representatives were involved in a two-step assessment process to select preferred options for improving the road.

    Our relationship has strengthened over time.

    We continue to work closely with Te Rūnanga. In 2020, Ngāti Tama members voted in favour of agreements with Waka Kotahi NZ Transport Agency, allowing land needed for the bypass to be exchanged.
