A tsunami warning has been issued for New Zealand following a 7.8 magnitude earthquake has struck off the Kermadec Islands this morning.
The Pacific Tsunami Warning Centre has issued a warning for New Zealand, Tonga and the Kermadec Islands.
The United States Geological Survey reports the quake struck at 7.03am at a depth of 48km, and was centred 211km east of Raoul Island.
John Bellini, a seismologist with the U.S. Geological Survey's National Earthquake Information Centre, said it was uncertain if a tsunami was on the way to New Zealand.
It would strike the East Cape around 9.00 am and Auckland around 10.00am.
This feels strangely familiar to the early reports of what became a devastating tsunami in Samoa a couple of years ago. We've got our fingers crossed that this particular event doesn't lead to deaths and widespread damage - more details as they happen...
UPDATE (8.20am): The Pacific Tsunami Warning Centre has cancelled the tsunami warning, although NZ Civil Defence is still warning of the possibility of sea surges throughout the day.
