The NZ Transport Agency (NZTA) has lowered the speed limits of seven North Island areas after communities expressed their concerns about their safety.
Effective immediatley, the speed limits will decrease for stretches of roads at Puhoi, Kaukapakapa, Pukenui and Houhora.
"We are grateful to the many people who've given us feedback as this demonstrates the lower speed limits will clearly be welcomed by the communities," NZTA's system design mangager Brett Gliddon said.
At Puhoi, north Auckland, the 80km/h speed limit on State Highway 1 through Johnstones Hill tunnel will be extended north to the Puhoi Rd intersection, down from 100km/h.
The speed limit from SH1 to the 50km/h zone in Puhoi village will also fall from 100km/h to 80km/h.
