A sting on Northland liquor outlets revealed none of the 16 businesses targeted breached the law by selling alcohol to minors.
It's the fourth consecutive time that a sting in Northland has seen no sales to minors and police say it shows most licensees were fulfilling their legal obligations.
Police have released the results of the latest Controlled Purchase Operation (CPO) which was carried out by officers and staff from the Northland District Health Board.
The operation audited 16 off-licensed premises in the Mid North and Bay of Islands area and involved under 18-year-olds attempting to buy alcohol from licensed premises.
Attempts were made at licensed premises in Kaikohe, Okaihau, Moerewa, Kawakawa, Opua and Paihia and there were no sales to minors.
