Occupational therapist Cameron Casey, 37, was metal-detecting with his dad Barry Casey in Lawson Park when his detector showed a “large target” buried 13cm under a tree on Tuesday.
“I was sort of expecting a can or something and I dug it up, I thought it was a crushed pipe, I find lots of crushed pipes,” Casey said.
“So I just put it in my bag and then when I got home, I sort of just put it out on the table and then I noticed the fuse and ‘I thought, oh, gosh, what have we got here?’”
Casey said it had gotten into the wrong hands it would have been “nasty” and “could have been fatal”.
When police arrived at his home the next day, he said they were “happy he had reported it” so it was “no longer floating around public domain”.
An NZDF spokesperson said an explosive ordnance disposal (EOD) team responded to a request for assistance from police after a member of the public had discovered a possible improvised explosive device whilst metal detecting.
“The NZDF EOD team assessed the item to be a metal pipe bomb which was rendered safe and disposed of in a safe manner,” the spokesperson said.
“Anyone who discovers a potentially dangerous item should always exercise caution until the item is deemed safe by an expert. If you do discover something that might be dangerous, remain clear of the item and contact New Zealand Police as soon as possible.”
Casey said this was the most interesting thing he had found during his three years of metal detecting.
Other treasures he has uncovered include a perfectly preserved wallet from 1946 complete with the shopping list and bus ticket, many shillings and other older coins.
“Mostly it’s mountains of bottle tops, cans and a lot of vapes,” Casey said.
