The Army has detonated a live World War II bomb after a family found it on their property at Kinohaku.
Te Awamutu constable Rainier Bron said a man notified police on Wednesday, June 6, about a mortar shell on his family's farm.
The family had owned the bomb for many years and as children had played with it on their grandfather's farm, he said.
"The grandfather used to be part of the Home Guard during World War II. They think that's where the mortar shell had come from."
"They never thought it was live and they lost track of it about 20 years ago but recently found it again."
