Map showng oversized vehicle movements as part of the Kaiwaikawe Wind Farm project Overnight oversized load movements for Mercury NZ’s Kaiwaikawe Wind Farm projectOver the next few months, regular oversized loads carrying wind turbine components will be moving on our state highway network overnight from Northport to the Kaiwaikawe Wind Farm site. They will be travelling in convoys between Sunday to Thursday nights to minimise impacts on daytime traffic. To avoid morning peak congestion, trucks will return to Northport along the same route after 9.30am.
There has been a lot of behind the scenes planning between Mercury Energy, the NZTA Maintenance and Operations team, bridge engineers, the NZ Police Commercial Vehicle Safety, and specialist transport load pilot crews to ensure these works are delivered as smoothy and safety as possible.

NZTA thanks road users and local communities for their patience and cooperation while these movements take place, and for helping keep everyone safe around oversized vehicles. Images show the turbine components at Northport – gives you a sense of just how big these loads are! Photo courtesy of Northport. |
