Four South Korean tourists in New Zealand were rescued from a hotel in Christchurch after a powerful earthquake hit the country's second-largest city on Tuesday, an official at the South Korean embassy here said.
The four had been trapped inside after a wooden staircase in the building collapsed, but were later saved by local rescue workers, the official said.
"No South Korean casualties have been reported so far," he added.
A 6.3-magnitude quake hit Christchurch on Tuesday afternoon.
Foreign news reports cited local police as saying there were reports of multiple deaths from the second tremor to hit the city in five months.
About 5,000 South Koreans are currently living in Christchurch. (Yonhap News)
