Calls from the community have led to speed limits on some Yaldhurst roads being lowered.
The changes, which come into force in December, include a reduction in speed on SH73 east of Yaldhurst as well as Ryans, Pound, Hasketts and School roads.
New Zealand Transport Agency director regional relationships Jim Harland said: "The speed limits on Yaldhurst roads have been the subject of ongoing community calls for reductions, particularly with the significant development in the area which has generated more pedestrian and cycling activity alongside traffic."
NZTA's speed review proposed slower speed limits for SH73 on the western urban periphery of Christchurch, extending west through Yaldhurst township.
