A group of volunteer divers with a mission to clean up Wellington Harbour have found their third piece of unexploded and potentially dangerous WW2 ammunition.
Ghost Divers pulled up a small brassy object over the weekend - which a historian has confirmed is a fuze mechanism.
The group called the Defence Force explosive ordnance disposal team to deal with it.
Previously group founder and president Rob Wilson has found two unexploded artillery shells at Shelly Bay, and he says there's a growing list of things they're instructed not to touch.
