A magnitude 7.3 quake has occurred in the Kermadec Islands.
The US Geological Survey reported the quake struck at 3.19am on Tuesday (1519 GMT on Monday) at a depth of 35km.
The Kermadec Islands are about 1,000km northeast of New Zealand.
The Institute of Geological and Nuclear Sciences told Morning Report the earthquake was too deep to cause a tsunami.
It said a 5.3-magnitude aftershock was recorded close to the original earthquake.
The Department of Conservation says its staff on Raoul Island felt the earthquake but report no significant damage.
DoC worker Mark Kearney died in 2006 during a volcanic eruption.
