Auckland Airport police say the discovery of a bomb that led to the cordoning off of parts of Auckland Airport this afternoon was the result of an innocent mistake by a passenger.
They say this sort of event is quite common at the airport, as people bring back World War I and World War II memorabilia regularly without realising the potential threat.
Acting Sergeant Chris Ridley says there was no malicious intent in today's incident but police have to respond as if the bomb is live.
Sergeant Ridley says the maximum penalty for today's offender is possibly only a fine.
The man declared the artillery shell to customs when he arrived at the airport.
He'd collected it as a souvenir on an overseas snorkelling trip.
