A strong magnitude 5.2 earthquake struck 20km west of Pōrangahau this morning and was widely felt throughout the lower North Island.
The tremor, at a depth of 10km, struck at 3.18am. It was followed several aftershocks, the biggest being a magnitude 4 shake at 3.30am.
More than 5000 people reported feeling the initial quake on the GeoNet website.
Central Hawke's Bay deputy mayor Kelly Annand said it was a "big quake".
"It made us all a bit aware that the earth can move again, we haven't had one for quite some time."
At 3.40am, GeotNet said there had been five aftershocks so far.
"There will likely be more.
"Remember in an earthquake: drop, cover and hold. When in bed, cover your head. You are less likely to be injured if you stay in bed."
Fire and Emergency said it had had no callouts in relation to the shaking, which was felt strongly in places.
It had also received no reports of any damage.
