There have been numerous reports of what appears to be a meteor shooting across the sky in the South Island and lower North Island.
Sightings of a "ball of coloured flame" or "silver fireball" have been witnessed in Christchurch, Whanganui, Wellington, Kapiti Coast, Nelson and Kaikoura between 6pm and 7pm on Monday.
One witness in Canterbury wrote on Weatherwatch.co.nz: "Was like a flying ball left with a jet stream sort of thing in the sky and was really bright!"
"Fantastically big, bright, and racing across the sky," said another witness in Otaki, Kapiti Coast.
Simon Holtham wrote on the website: "I saw this too, it was like something out of a movie, ball of coloured flame shooting towards the earth from west to east, a couple of flashes, lots of smoke which stayed in the sky for ages, and then gone."
Another person said: "Seen bright light flying in high speed with huge tail over looking the Cook Strait."
