The Canterbury Earthquake Recovery Authority is on track to have the residential red-zone cleared by April next year, with more than 7,000 homes demolished so far.
The February 2011 Canterbury earthquake led to just over 8,000 homes in Christchurch and the Waimakariri District being red-zoned.
Of the 4,000 red-zoned homes on the Port Hills, 167 have been cleared, and clearance of another 45 properties is underway.
The authority said over 7,000 homes on crown-owned flat land had been cleared.
It said 17 of the 39 homes on flat land were still to be cleared but cannot be, due to unresolved insurance issues.
