There are three major construction sites, these will operate for 3 to 6 years.

  • Western Springs

  • May Road in Mt Roskill

  • Māngere Wastewater Treatment Plant

We’re starting construction at 2 of the major construction sites this year. You can see what’s happening at these sites below. We’ll post updates on all the other sites in 2020, when we get nearer to construction. There are also 13 smaller construction sites to build connections to the tunnel, which will operate between 12 -18 months. All construction sites are shown on the map (click to enlarge).
