There have been about 300 temblors in five days and officials have since doubled their estimate for repairing the earthquake-stricken city. The latest rumbling registered 5.1 and was located just 10 kilometres outside the city. No one was injured.
“My guts are just churning up here. When will this thing end? It is like living in a maelstrom,” Christchurch mayor Bob Parker said.
“We were starting to think maybe, just maybe, we are over the worst of this, and now we have had this shocking event,” Parker told NewstalkZB radio. “This is a hammer blow to the spirit of a lot of people.”
Some 500 buildings were destroyed after Saturday's earthquake and 1,600 of the area's 100,000 buildings are said to be damaged. New Zealand's treasury secretary said restoring the buildings could cost NZ$4 billion.
