Staff at a Whangārei dairy were forced to flee their store after being confronted by a trio of young men armed with what appeared to be a shotgun.
The three youths approached staff at the Maunu Superette, on the corner of Maunu Rd and Porowini Ave, on Tuesday around 6.20pm.
A police spokesperson said the workers were able to flee to safety and successfully triggered the store's fog cannon as they escaped.
The trio made off with a stash of cigarettes taken from the superette's supply before making a getaway in a stolen Mazda Atenza parked nearby.
