The museum has been evacuated.
Taupō police Senior Sergeant Tony Jeurissen said Taupō Museum staff had found what was described as a "metal cylinder with wings" in a storeroom this morning.
He said it had 'remove before firing' written on the bottom which led them to think it was explosive.
There was no paperwork for the item and staff were not able to locate it in their records.
The council's communications manager Lisa Nairne said it appeared the item had been received before the register started.
"We can't confirm how long it's been there."
More to come.
