“It gave us all a bit of a shock,” Wanaka Tourism Office general manager James Helmore told Fairfax NZ News, as shaking persisted for some 15 seconds.

“There may be some minor damage in plastering” he said, but there was none he could see at that moment.

Local media is also reporting evacuation at the Wanaka Puzzling World attraction park.

“It was significant, we evacuated quick because we didn't know whether it was going to get worse,” Heidi Landsborough of Puzzling World said. “It was a bit difficult because we had a few people who thought it was part of the experience.”

New Zealand partially lies on the eastern margin of the Australia plate which is one of the most seismically active areas of the world, due to the convergence of the Australia and Pacific plates.
