There was a swarm of small earthquakes in the central North Island on Sunday morning.
The Institute of Geological and Nuclear Sciences said about 25 small quakes were recorded following two tremors near Turangi.
They occurred at 8.11am and 8.30am on Sunday at a depth of 2km, measuring 2.9 and 3.3 respectively, 10km north of Turangi.
GNS Science says the swarm is nothing for people to be worried about and happens about every two or three months in the Rotorua-Lake Taupo area.
Another earthquake measuring 3.6 on the Richter scale, was registered at 8.01pm on Saturday, within 5km of Norsewood in Hawke's Bay, at a depth of 50km.
