6.4 magnitude earthquake rocks NZ
A strong quake has been felt across New Zealand this afternoon.
The 6.4 magnitude quake was centred 35km north-west of Kaikoura, on the east coast of the country's south island, at a depth of 83km, GeoNet said.
GeoNet described the quake as "strong".
New Zealand Herald reader Paddy Brocherie wrote in to describe the quake as "the longest quake I've ever felt and I live in Christchurch".
"Bad, bad, bad."
Susan Allan said she felt the earth move in Riwaka - a "sharp rolling jolting for approx 30 seconds".
The quake shook the house, but there was no damage, she said.
Public information specialist for GeoNet, Caroline Little, said the magnitude 6.4 quake was centered 40km north west of Kaikoura.
She said those in Kaikoura were sure to have felt the tremor.
"The deeper the quake, the more rolling the shaking is rather than that violent shaking - they definitely would have felt it."
Ms Little said there were reports of the quake being felt as far south as Timaru, and as far north as Hamilton.
