Four on-licences were caught selling alcohol to minors in a police sting last night - one minor as young as 15.
Police in the Auckland city district targeted eight places.
The four premises - in Ellerslie, Panmure and Newmarket - will be prosecuted under the Sale and Supply of Alcohol Act. Their cases will be heard by the Alcohol Regulatory Licensing Authority.
Last night's operation comes just a month after five premises in the western area of Auckland city district, sold alcohol to minors in a separate operation.
"It's really disappointing and frustrating that we continue to have premises seemingly flout the law and their obligations," said Inspector Gary Davey, Auckland city police district prevention manager.
