A number of Christchurch residents want their neighbourhood to be condemned, as liquefaction following Friday's earthquake forced another clean-up.

Aftershocks continued to rock Christchurch on Saturday after quakes measuring 5.8 and 6.0 shook the nerves of many residents on Friday.

The quakes cut power to about 26,000 homes and caused issues with water supply and wastewater, though most of those services were back to normal by late Saturday.

But cleaning up huge amounts of silt caused by liquefaction was the biggest problem for many residents in the suburb of Parklands, who have already faced this issue twice before.
