Police descended on an area in Auckland's North Shore after reports of a suspicious package.
A police spokeswoman said they were called about midday by someone reporting a suspicious-looking item in front of a property on Stanley Point Rd.
It appeared the item was a piece of historic military equipment, she said.
"Our main role was to ensure the public's safety and there was no threat to the public."
The NZ Defence Force Explosive Ordnance Disposal Team also attended the incident.
