Police in Counties Manukau believe three aggravated robberies of service stations in the past week are linked.
The first was at a Mobil station in Glen Innes last Friday, the second at a Mobil station in Mount Wellington on Wednesday and the latest at a Caltex station in Penrose on Thursday.
In the third incident, an attendant was assaulted with a firearm. Cash, cigarettes and other items were taken.
Police say there are similarities between the incidents and they are looking for Breyarn Hose, 17, to assist them with their inquiries. He is believed to be in Auckland, but has no fixed abode.
