NZTA seeking feedback on State Highway speed review NZTA says the focus on making safer roads for all is evident in the current programme of works for Northland and into Auckland, such as the Ara Tūhono – Pūhoi to Warkworth motorway. Speed limit reductions could be on the cards for the region’s two State Highways as a result of a review being carried out by the Waka Kotahi NZ Transport Agency (NZTA) in Northland and Rodney this year. Over the next couple of months, NZTA will be organising community information sessions to get feedback from local people on State Highway 1, from Warkworth to Whangarei, and State Highway 16, from Wellsford to Waimauku.
