Firefighting operations could continue at Port Hills for up to a month as thermal imaging is still identifying new hotspots that could flare up within the fire zone.
A Christchurch Civil Defence update said the area was still an active fire zone, but 95 per cent of the fire perimeter area is now controlled.
"As long as hot spots remain in the Port Hills we will have a presence and this could be for some time, possibly up to four weeks unless there is a significant change in the weather," principal rural fire officer Darrin Woods said.
Civil Defence said drone photography and thermal imaging showed hotspots in most areas.
