Strong earthquake rattles central North Island

A 5.4 magnitude earthquake has struck 30km east of Wairoa, reports Geonet.

The quake was initially recorded as having a magnitude of 5.6.

The quake was 27km deep, with "strong" shaking reported.

It struck at 6:16pm.

The tremor was also felt in Cambridge, Hamilton, Eketahuna, Napier and Whakatane, among other places.

It follows a 4.7 magnitude quake north of Milford Sound earlier on Tuesday.

Geonet said there have been nine aftershocks from the North Island quake, ranging from magnitude 1.9 to 3.4. The aftershocks were "not unexpected for a quake of this size".

The quake was centred west of the Mahia Peninsula, with Geonet saying it had received "over 3000 felt reports, largely from Hawke's Bay and Gisborne areas".

Civil Defence in Hawke's Bay said there was no tsunami threat.

"Tonight's earthquake near Wairoa was a bit of a shake, but not enough to be a 'long or strong, get gone' quake," Civil Defence posted to Facebook.

It reminded people that the natural warning sign of a tsunami was a quake that lasted longer than a minute or strong enough to knock you off your feet.

"But if you ever feel you should evacuate, please don't wait for an official warning - head to high ground or inland." 

There have been no reports of damage to buildings or people. 

Various people reported feeling the quake on Twitter.

"Bit of a sway in Opotiki," wrote one person.
