Wigram Skies, Broken Run, Awatea Park, Awatea Green and Magnolia Estate subdivisions, along with the business area of Lodestar Avenue and Stark Drive may be reduced from 50km to 40km.
The Christchurch City Council is also proposing to install P60 restrictions in the shopping section at The Landing to help customers find car spaces throughout the day in the busy central area, and in Skyhawk Road to keep the cycle lanes clear.
People can provide feedback on the draft safer speed plans via the council's Have Your Say webpage, with the deadline for submissions being November 18.
A final decision is due in December, with any changes in place by the end of January next year
Council transport operations manager Steffan Thomas said the safer speeds will benefit residents in a growing and very popular area of the city.
"Many families, along with several businesses, have moved to the wider Wigram area and we are very conscious of the need to ensure that speed limits support a safer environment,"
"Speed determines both the likelihood of a crash occurring and the severity of the outcome. Regardless of what causes a crash, whether people walk away or are carried away will depend on the speed the vehicles are travelling."
