ABC News (NZ): The New Zealand Government's early estimate suggests there is now around $10 to 12 billion worth of earthquake damage in Christchurch. The September earthquake mainly hit residential areas, but this time it was the central business district that bore the brunt. New Zealand's prime minister John Key says that indicates the economic impact of yesterday's earthquake will be worse. "I'm not an engineer, but my on the ground assessment of looking at those buildings - it's going to be quite some time before the CBD is operational," he said.
