A short, sharp magnitude 5.1 quake rocked central New Zealand at 3.46 this afternoon.
GeoNet changed its initial report to upgrade the quake from magnitude 4.9 and a depth of 103km to 5.1 and 76km respectively. It was centred 15 km west of Ohakune, at 3.46pm. There were no initial reports of damage.
Duty seismologist Lara Bland said it was ''the magnitude where people feel it quite strongly''.
While it felt like two quakes it was actually the same one in ''two phases of energy'', she said.
The first wave felt like a ''bang''.
''After that you got more shaking. Within minutes, more than 3300 people reported feeling the quake to GeoNet, from Otago to Auckland."
In Taranaki, residents described it as a big jolt.
"Was pretty good here in Whalers Gate [New Plymouth], had to hold the TV so it wouldn't fall over," said Jimmy Kurth.
Andrea Russell said she was on the third-floor of a building.
''[It was] quite a big jolt to start with then just a gentle sway but it went for quite a while."
