Bay of Plenty police caught fewer locals selling alcohol to minors in controlled purchase operations last year- despite more checks on licensed premises.
Police figures showed 11 premises were nabbed selling booze to youngsters in operations at on and off-licences in the police district in 2014 compared with 27 in 2013.
In 2013, 214 controlled purchase operations were carried out and in 2014 there were 244.
The Bay of Plenty Police District covers the area from Katikati in the north, east to the tip of the East Cape and south past Turangi in the central North Island.
Inspector Kevin Taylor of Bay of Plenty police said there were a number of potential reasons for the drop in premises found supplying to minors.
