Lord Howe Island, NZ, on tsunami alert over 7.6 Pacific quake.
A tsunami warning has been issued for Lord Howe Island, off the NSW coast, after an earthquake near the Loyalty Islands within New Caledonia.
New Zealand authorities are also on alert, urging residents along its northern coast to avoid beaches and shore areas.
The New Zealand National Emergency Management Agency said people should get out of the water, off beaches and away from harbours, rivers and estuaries in areas from Ahipara to Bay of Islands, Great Barrier Island and from Matata to Tolaga Bay.
"We expect New Zealand coastal areas to experience strong and unusual currents and unpredictable surges at the shore," the agency said in a statement.
