A 5.6 magnitude earthquake has shaken Southland.

The quake struck 30km west of Te Anau at 2.55pm, according to GeoNet.

GeoNet reported the intensity as strong.

A fire service spokesman said it was a "good shake" but no reports of injuries or damage to building were reported.


There were reports of the quake being felt as widespread as Oamaru, Haast and Bluff.

It was felt in the main centres of Dunedin, Invercargill and Queenstown.

In Te Anau, the Ranch Bar and Grill duty manager Hayley Dawson said the quake was large enough to shake glasses and get the five patrons in the bar at the time talking.

''The local handles were all rattling,'' she said.

Previous quakes Ms Dawson experienced over her year living in the town she had not noticed, but she ''did notice this one''.

Fresh Choice Te Anau owner Keith Cullen said the quake was ''rapid'' but was not severe enough to send stock from shelves.

''We certainly felt it,'' Mr Cullen said. ''It was quite a quick shake.

''I just shot down to the shop floor but no-one was worried or scared.''


Mr Cullen said it lasted about 10 to 15 seconds and was ''a lot bigger than most'' he had felt in his 15 years in Te Anau.

Another quake, of magnitude 4.3, shook Fiordland this morning.
