The difficult and dangerous work of quelling the fire on the hills above Christchurch goes on as cordons continue to be lifted.

Drizzle is helping firefighters but is also restricting access to some areas.

The blaze, which has destroyed 11 homes and ripped through more than 2000 hectares of scrub and forest since Monday, remains largely contained and work continues on hotspots and building fire breaks.

The Fire Service is concerned about the area around Victoria Park and east of Dyers Pass Road, electronic equipment on Marleys Hill and the southern flank of the fire.

Police and the NZ Defence Force continue to patrol cordoned off areas.

Many people have returned to their homes but more than 100 have registered to gain access to their properties behind cordons.

The cordon is now above 236 Dyers Pass Road, the last house on the road up the Port Hills from the suburb of Cashmere.

The cordon on Victoria Park Road is also now above the last house on this road, which is the entrance to Victoria Park.

Residents in houses up to, and including, houses at 299 and 304 Kennedys Bush Road, can now access their properties.

A community meeting was held this morning to keep residents up to date on developments. Around 400 residents turned out to the meeting in which frustration and indignation was directed against emergency services officials and authorities.

Firefighters worked through the night to ensure the fire remains within its 29km perimeter, ahead of fire retardant being applied by planes this afternoon.

Lieutenant Colonel Rob Loftus says nine army chefs will prepare three meals a day for at least 250 emergency workers from a field kitchen set up at Hallswell Quarry.

The Christchurch Adventure Park remains in the hands of the fire authority and within the cordon.

"At this stage we have been unable to get into the top of the park to do a full and proper assessment. However we do know that there is significant damage," the park says.
