A magnitude 5.5 earthquake has struck 70km north-east of Collingwood and has been felt widely throughout central New Zealand.
GeoNet reports the quake was at a depth of 190km. Collingwood is at the top of the South Island, near Farewell Spit.
More than 11,000 people have reported feeling it on the GeoNet website. Most reports were from people living at the top of the South Island and bottom of the North Island, but some reported feeling it in Auckland and as far north as Northland.
Many people have taken to social media, saying they felt the quake, and some said they received an alert about the earthquake before they felt it.
