A 5.7 magnitude earthquake has struck near Christchurch, on New Zealand's east coast.
The quake caused cliffs to collapse into the sea, but no injuries and no major damage to the city was reported.
The epicentre of Sunday's earthquake was 15km east of Christchurch, the country's seismological body Geonet, said.
Christchurch Mayor Lianne Dalziel said: "Obviously with a 5.7 magnitude earthquake so close to the eastern coast of Christchurch its certainly been a big shock for the city, a set back in terms of people's confidence and feeling of security."
In 2011, Christchurch was devastated by an earthquake which killed nearly 200 people.
