The lower North Island has rattled and rolled all night long after a severe jolt put the jitters under many last night.
The largest of a series of quakes measured 5.8 and struck at 9:05pm yesterday, 15km east of Pongaroa and at a depth of 24km.
Pongaroa is on the Wairarapa coast, northeast of Masterton.
The GeoNet website says 5265 people reported feeling the "severe" quake, some as far north as Auckland and south to Invercargill.
Most reported it as a light quake.
One person in Dannevirke reported it as damaging but the Fire Service said no one had reported any damage to it.
It was followed by quakes measuring 3.5, 3.8, 4.1 and 4.4 before a 2.8 tremor about 5:27am today.
GeoNet seismologist Caroline Little says aftershocks could continue for weeks, and some may reach magnitude 5.
The area was no stranger to earthquakes, with four above magnitude 5 in the last 20 years within 60km of Pongaroa, she said.
