A man who robbed a Whangarei supermarket at gunpoint sparked an armed offenders callout in the city.
Police said a man armed with a short-barrelled firearm handed a threatening note to a checkout operator at Tikipunga Countdown on Monday night and was handed a sum of money.
He fled, and the armed offenders squad was later called to a nearby house.
They carried out a search but no arrests were made.
The checkout operator was unhurt but extremely shaken and upset, police said.
