It is unlikely that more homes will be red-zoned in the Port Hills area after thousands of tonnes of rock came down in yesterday's quake, says Land Information New Zealand.
In the Port Hills area 712 homes have been red-zoned and 498 of them are now owned by the Crown.
LINZ group manager Brenden Winder said the red-zone offer had expired and he did not expect more homes to be reclassified.
He told Checkpoint their priority was to assess the stability of the areas where the collapse occurred, before resuming work there, which would take a few days to complete.
Council owned facilities nearly all operating again
All Christchurch City Council-owned facilities have been checked since yesterday's quake, and are operating as normal, except for one.
Just the Linwood Service Centre and Library remains closed until repairs to light fittings can be carried out.
A council spokesperson said Horncastle Arena and the Hadlee Pavilion were inspected by structural engineers today and preparations are continuing for this weekend's New Zealand-versus-Australia test cricket match at Hagley Oval.
The spokesperson said geotechnical engineers were closely monitoring slope stability in affected areas of the Port Hills.
Christchurch Mayor Lianne Dalziel said the quake was a shock for a lot of people contributed to by the fact that it was the biggest aftershock the city has had in four years and there was no rumbling noise before the shake and it happened quite suddenly.
"We've lost the memory of what it was like, we had over 50 aftershocks over magnitude five between September 2010 and December 2011, we actually got used to them."
She said the latest quake was a reminder of New Zealand's natural hazard environment.
Ms Dalziel said Christchurch felt like a much more secure environment than it did after the 2011 quake.
Liquefaction ... again
A Christchurch resident living in an uninsurable home said Sunday's quake had her worried she would be made homeless.
Bower Ave homeowner Alice Mardel said she bought her home in a damaged state knowing that it was uninsurable but hoping there would be no more large shakes.
She said yesterday's quake had her in a panic that her home would receive further damage that she would not be able to afford to get fixed.
But Ms Mardel said she was thankful it pulled through without a scratch.
A couple who live on Bower Ave which was badly affected by silt from liquefaction said they were worried yesterday that they might be back to square one with sorting out their lives.
Yesterday's quake left most parts of the city unscathed but resulted in more silt and a sink hole appearing on Bower Avenue in Parklands.
Allyn Bettridge and Josie Hartley were in Lyttelton when the quake struck and quickly returned home to see if their house, which was only rebuilt 12 months ago, had survived the shaking.
Apart from a giant sink hole in the road outside their home and piles of silt, there was no damage and only the job of picking up a few items off the floor.
Mr Bettridge said Bower Ave was due to be sealed today for the first time since the February 2011 quake, something which will now have to wait a bit longer.
