Lower speed limits will come into force on more than 600 roads across Auckland today, including the central city.
Most speed limits will go down from 50km/h to 30km/h. However, Nelson, Hobson and Fanshawe Sts will each have a new speed limit of 40km/h, down from 50km/h. Some shared streets like Federal St will continue to have a 10km/h speed limit.
Freemans Bay on the outskirts of the central city and Te Atatu South are other urban areas where the speed limit is being reduced from 50km/h to 30km/h.
Speed limits are also being reduced on many rural roads in Rodney and Franklin, where the 100km/h speed is typically being reduced to 80km/h.
Auckland Transport safety manager Bryan Sherritt said Auckland is a Vision Zero region and no one should lose their life or get seriously injured simply moving around the city.
