MetService meteorologist Angus Hines said there were thunderstorms forecast for the area, so although not predicted, it was possible for there to be tornadoes forming.
"Tornadoes in New Zealand are usually not big enough to appear on radars so are hard to forecast," Hines said.
"This looks to be a funnel cloud, which is kind of like a miniature tornado that moves downwards from the base of the cloud but doesn't actually reach the surface to cause much damage."
