Aftershocks have been felt after a severe quake measuring 5.8 rocked the lower North Island, with GeoNet warning the shakes could continue for weeks.
The 24km-deep quake struck 15km east of Pongaroa, on the east coast near the border between Wairarapa and Manawatu, about 9pm yesterday.
Houses swayed and items shook off shelves, but there have been no reports of serious damage.
The quakes was felt by more than 5000 people from as far away as Auckland and Invercargill, GeoNet said.
A series of aftershocks meant a sleepless night for many, with 10 smaller shakes recorded and some getting up to "moderate" intensity, GeoNet said.
GeoNet scientist Caroline Little said there had been "a few foreshocks" earlier yesterday, with the largest being a magnitude 3.8 quake in the same location.
Within he first 35 minutes of the 5.8 quake there were almost 4000 felt reports coming in from much of the North Island, she said.
The Ministry of Civil Defence said there was no tsunami threat after the quake.
Residents in Pongaroa said the quake lasted about 30 seconds and was a shuddering, rolling quake.
Whakataki Hotel manager Dave Hastie was sitting in the pub at the time, which is located several kilometres south of where the quake was centred.
He initially thought it was just a blustery wind and said it lasted about 30 seconds.
"It was one of the better ones," he said. "I thought of dashing outside."
A Havelock North resident said: "it went for 30-40 seconds swaying the curtains. Glass flexed in the window frames. Low frequency noise".
John Booth, the Mayor of Carterton District, said the quake "Gave the old farm house a good rock and roll, feel like I'm on a boat".
Pongaroa is a small town in the Tararu District, part of the Manawatu-Wanganui region. The town lies 110km southwest of Hastings. The village itself has a population of about 100 while the surrounding farms bring the local population up to some 300.
