In northwest Auckland, a new limit of 80km/h will be extended north of North Cres to west of Kanohi Rd on SH16 at Kaukapakapa.
South of Kaukapakapa village, the exisiting 50km/h zone will be extended southeast of Opoto Pl on SH16 and the stretch of road south of Opoto Pl will decrease from 100km/h to 80km/h until after Henley Rd.
In Houhora, Far North, an 80km/h speed limit will be put in place on SH1 south of Saleyard Ave to north of Harbour View Rd. A 50km/h speed limit will be introduced north of Harbour View Rd to south of Harbour View Rd for the Pukenui community as well.
Gliddon said the residents had expressed concerns that the legal speed limits in their areas were too high and they were concerned for their safety.
"Reducing speed limits and making the road and roadside more forgiving of human error reduces the risk of crashes and limits their severity," he said.
