A heavily armed gang may be responsible for a spate of robberies at South Auckland banks and bars, police say.
The same people were likely to be behind seven aggravated robberies in Otahuhu, Otara and East Tamaki in June and July, Counties Manukau Detective Sergeant John Love told the New Zealand Herald.
In each case the thieves were disguised and used a variety of weapons including pistols, axes, knives and a World War 2-era rifle.
"It's a crew who have gone on a bit of a roll and generally they don't stop unless they get caught, so we want to try and stop them," Mr Love said.
"They get more and more brave as they get on ... someone will get hurt."
Mr Love said there had not been any robberies since July 14 but the gang had stolen a lot of money "so maybe they're just sitting quiet at the moment".
A number of stolen vehicles were also used in the raids.
Anyone with information about the robberies should contact police, Mr Love said.
