New Zealand quake tsunami warnings cancelled

WELLINGTON/SYDNEY (Reuters) - New Zealand and Australia cancelled tsunami warnings on Wednesday after an earthquake struck the south of New Zealand, causing minor damage but no injuries.

Australia's weather bureau said a small tsunami had been recorded in New Zealand and another was detected in the Tasman Sea heading towards Australia's southeast coast.

"Our deep ocean buoy in the southern Tasman Sea indicates a wave travelling across the Tasman. Because of the depth of the water we can not tell the wave height," Chris Ryan, from Australia's Tsunami Warning Centre, told Reuters.

Australia's Bureau of Meteorology issued a statement advising people in low lying coastal areas to move to higher ground and for people to get out of the water.

Australia cancelled its tsunami warning after an hour, downgrading the threat to a "small boat alert". New Zealand also cancelled its tsunami warning.

The Institute of Geological and Nuclear Sciences said the tremor, measuring 6.6 magnitude, struck at 9.22 p.m. (0922 GMT).

The government institute said it was centred in the remote and unpopulated Fiordland region, about 150 km (95 miles) north west of the the country's most southern city, Invercargill. It was measured at around five km (three miles) below ground level.

Local civil defence officials had issued a warning about a "potential tsunami" for the region, because of conflicting reports about the quake's size. The Japanese meteorological agency put the preliminary magnitude at 7.8.

"There was a small wave, but it was not damage causing ... people probably wouldn't have noticed it among the other waves," Civil Defence spokesman Vince Cholewa told Reuters.
