A magnitude 5.5 earthquake has struck near Taupo and was felt throughout the Bay of Plenty and as far away as Hawke's Bay.
The quake struck at 12:42 pm 10 km north-east of Taupo at a depth of 108km.
GNS Science data centre manager Kevin Fenaughty said the quake was unlikely to be damaging, but was widely felt on the East Coast.
"Generally the East Coast feels them stronger than directly above where it occurred because the shaking energy is transferred more effectively up the plate boundary to the east."
The East Coast of the North Island is situated where the Pacific and Australian tectonic plates intersect.
On Monday, another earthquake centred 15km south-east of Tokoroa at a depth of 195km was also felt in Hawke's Bay, and in Wellington and Nelson.
People took to Facebook as the quake hit.
