A magnitude 6.1 earthquake struck off the coast of the North Island this afternoon - the biggest since Friday morning's magnitude 7.1 quake that struck at 2.27am.
Today's 6.1 quake hit at 1.16pm 140km, east of Te Araroa in the Gisborne region, at a depth of 33km.
GeoNet reported the shaking as "moderate".
More than 1000 people recorded feeling the earthquake.
A number of people took to social media to report what they felt.
"Gisborne. That was a good one, felt like it last for a full minute of strong but gentle rocking," one person wrote.
Another said: "That definitely got the heart going!! Was hoping it wasn't going to get worse."
The 6.1 quake comes after a number of small tremors had been felt off the coast of East Cape overnight and this morning.
At 10.30am, a 5.4 magnitude quake struck 125km east of Te Araroa at a depth of 12km, a magnitude 4.4 quake struck 135km east of Te Araroa at 8.56am today at a depth of 12km.
A 4.7 quake was registered at the same location and depth, at 7.58am today. GeoNet labelled it "weak".
A flurry of 12 small earthquakes registering between 3 and 4.7 also occurred between 6pm and 9am off the coast of Te Araroa.
GeoNet said the most likely scenario in the next 30 days is that further quakes of smaller magnitude will occur - and less often.
