A New Zealand tsunami warning has been cancelled but people and small boaters will need to be careful in the water in all parts of the area, officials said.

New Zealand's Ministry of Civil Defense & Emergency Management issued an advisory stating that they expect there will be unusually strong tidal surges and currents. They have advised that people and those with small boats use caution and their discretion before entering the water or going out in small boats, according to the agency's website.

A powerful earthquake struck off the Kermadec Islands of New Zealand, triggering a tsunami in the area, according to the U.S. Geological Survey and the U.S. Pacific Tsunami Center. The magnitude of the quake was initially 7.8, and it resulted in a tsunami warning for New Zealand, the Kermadec Islands and Tonga.

USGS added that the quake struck at 7:03 a.m. (local time) on Thursday, about 131 miles east of Raoul Island, which is part of the Kermadec archipelago, and was only 30 miles deep.

A report from the Pacific Tsunami Warning Center stated that sea level readings indicated that the tsunami that was generated may have been destructive along coasts near the epicenter of the quake.
