A 16-year-old boy has been charged following the attempted aggravated robbery of a Grey Lynn dairy on Tuesday evening, police say.
Detective Inspector Scott Beard, of Auckland, said the teen has been charged with assault with intent to rob and aggravated wounding. He's been remanded in Oranga Tamariki care until July 16.
A mother and her adult son are recovering from surgery after being stabbed at the Hylite Dairy on Great North Rd.
Police are also trying to find a male who they believe can help with their enquiries, Beard said, releasing a photo of the person they are seeking.
