Firefighters say it's lucky no-one was hurt when what's described as a mini tornado ripped through two streets in Invercargill on Friday afternoon.
Station Officer Greg Koppert says they found debris scattered about several properties in Glenalmond Crescent and Rockdale Roads.
The mini tornado lifted an entire corrugated iron fence from a house in Glenalmond Crescent and threw the fence on top of a parked car, smashing the window and penetrating the passenger seat.
Another section of fence smashed a bedroom window of a nearby house.
Trees and other fences were also blown over and three roofs had iron lifted.
Koppert says one resident estimated the wind at 170 kilometres an hour.
