Here’s a snapshot of what’s happening onsite and behind the scenes – December 2021 update.


Our first earthworks season concluded in early October, with over 650,000 cubic metres of earth moved since construction began in January. We have already moved over 10% of the project’s total and by the end of this earthworks season, we plan to have moved around half of the project’s total earthworks.

Te Ahu a Turanga is one of the largest earthworks projects in the country and has around 120 pieces of large machinery onsite.

Eastern access – Woodville

Looking from the current highway in Woodville, you can see Cut 30 taking shape as material is shifted downhill to form the embankment that will eventually lead up to the Mangamanaia Stream Bridge. Further uphill the temporary construction haul road is progressing up the ridge, and the forestry block is being felled. Work on Cut 28 is now visible. When finished, this cut will be around 50m deep.

Western access – Ashhurst

Access tracks from Saddle Road into the western end of the highway area are nearing completion. These tracks enable access to the Eco Bridge area and to the largest cuts and fills on the project.


Steady progress is being made to the bridges and underpasses along the alignment. The first piles have been installed on the Parahaki Bridge, across the Manawatū River. Work also continues on the remaining wall of the Nutcracker Farm Underpass near the Ashhurst end of the highway. And at the Woodville end of the project, the Morgan Road Underpass has had its roof poured, which will enable the adjacent culvert to be constructed.


Our landscaping teams put more than 250,000 native plants in the ground at two sites this year, as part of the project’s ecological offset planting programme. Maintenance of these plants will continue for the next five years. Preparations are also under way for the 2022 season, with a total of 600,000 plants to be planted at three offset sites.
