Four liquor outlets in Northland have been caught selling booze to minors in a sting by police and Northland District Health Board.
The Controlled Purchase Operations saw underage volunteers, aged 17, attempt to purchase alcohol from 18 licensed premises in the Bay of Islands and 16 outlets in Whangarei.
Four liquor outlets, two in the Bay of Islands and two in Whangarei, sold alcohol to minors.
Senior Sergeant John Fagan, area prevention manager for Whangarei/Kaipara, said the result was disappointing.
"All premises selling or supplying alcohol are aware that we run these types of operations regularly so should not be surprised that they are being tested. We expect that all premises should guard against sales to young persons and have the right procedures in place," he said.
