"It is a privilege, not a right, that licensees and duty managers are granted the ability to sell alcohol and we expect them to take their responsibilities around the sale of alcohol extremely seriously,'' Patrick said.
"To sell to minors who are carrying, and on request presenting, legitimate identification showing they are under the legal purchase age is unacceptable.''
Police will be applying to the Alcohol Regulatory and Licensing Authority (ARLA) for orders in relation to each sale to the minor during the CPO.
The operation was conducted by Northland Police Alcohol Harm Prevention Officers, the Whangārei District Council and Northland District Health.
The consequences when the licensees are reported to the authorities are major and can result in their licence to sell alcohol being suspended for several days, large fines and even the licence being cancelled.
