A magnitude 7.2 earthquake has struck near New Zealand's Kermadec Islands at a depth of 30km, the US Geological Survey says.
The Pacific Tsunami Warning Center said no destructive widespread tsunami threat existed, based on historical earthquake and tsunami data.
The USGS gave the epicentre as 73km south-southeast of Raoul Island.
Raoul Island is the biggest in the Kermedecs group of islands which are between 800km and 1000km north-east of New Zealand.
The Kermadecs are made up of a chain of about 80 volcanoes, stretching for 2600km between Tonga and New Zealand. The area is well-known for volcanic activity and earthquakes.
