The Dunedin City Council approved the suite of speed limit changes at its meeting on October 27.
Council transport group manager Jeanine Benson said the changes would take effect over the next few months, beginning with an extension of the 30kmh speed limit zone in the central city and the introduction of a 30kmh limit in the Green Island shopping area, before Christmas.
Those would be followed in the new year with lower speed limits for parts of Otago Peninsula, Port Chalmers, Mt Cargill, Blackhead and Scroggs Hill.
The changes were aimed at reducing the number of deaths and serious injuries on Dunedin roads, she said.
Between 2016 and 2020, 28 people were killed in crashes and 231 people were seriously injured on Dunedin roads.
Four of those deaths and 107 of the serious injuries involved pedestrians, wheeled pedestrians, cyclists and motorcyclists.
"These numbers are unacceptable," Ms Benson said.
"Reviewing and ensuring that speed limits across the city are set at levels appropriate for road function, design and use is a key measure we can undertake to improve safety on our roads."
The speed limit changes will come into effect as signage is updated over the next few months.
All changes are listed on the council’s website.
