New Zealand is still being shaken by a string of aftershocks a day after strong earthquakes that triggered a tsunami warning.
Three large earthquakes hit early on Friday off the coast of the North Island and prompted evacuations and a tsunami warning that was cancelled in the afternoon after the threat of a large wave passed.
On Saturday, the local GeoNet monitoring centre registered more than a dozen aftershocks with a magnitude over 4 from the early hours, including a magnitude-6.1 and 5.4. Most were marked as weak.
The US Geological Survey also recorded a series of aftershocks.
Seismologist Matt Gerstenberger said the continuing earthquakes are normal but warned the public to stay vigilant about the danger of a tsunami, in comments reported by Radio New Zealand.
Early on Friday, three large earthquakes occurred offshore, beginning with a 7.1-magnitude quake off New Zealand's East Cape.
That was followed shortly after by a 7.4 and a 8.1-magnitude quake near the Kermadec Islands, some 800 kilometres off the northeast coast of New Zealand's North Island.
In February, New Zealand marked 10 years since a major Christchurch earthquake that left 185 people dead.
