Two premises have been busted selling alcohol to minors in a police sting in the Nelson Bays area.
A joint Controlled Purchase Operation run by police, the district licensing agencies and public health was held last Saturday.
A total of 20 on and off licensed premises were visited by 17-year-old volunteers in the Nelson, Tahunanui and Stoke area and two sold them alcohol.
Police called the outcome "disappointing" and follow-up meetings will be scheduled between the managers and staff who sold the youths alcohol, police and the Nelson District Licensing Inspector.
Enforcement action would also be taken through the New Zealand Alcohol Regulatory Licensing Authority, police said.
