A proposal to decrease the speed limit in inner-city Auckland is being seen as a way to future-proof the city

Auckland Transport wants to lower it it to 30 kilometres an hour inside the central city motorways.

Heart of the City chief executive Viv Beck says there's already a 30 kilometre an hour limit in Queen Street, parts of Wynyard Quarter and the Viaduct already.

She says it won't make a massive difference.

Beck says it's changing the city for the future, where there are already a lot of people living, walking and cycling.
