A clip, entitled "UFO over Dunedin NZ", has sparked a flurry of comments on the video sharing website, YouTube, since it aired this week.
The footage was shot in Dunedin over two consecutive nights - last Sunday and Monday.
The person, who was camping at the time, said the object was "visible for about 10 minutes, eventually going behind a ridge of hills to the west out of sight".
"The light appeared, grew in brightness, changed colour, shape and moved in relation to the land from east to west over Dunedin," the person said.
"I am going to have the whole footage analysed as soon as possible."
However, other viewers remain sceptical, suggesting the footage could show landing lights on an aircraft, a bright star, or a planet.
