The number of local premises caught selling alcohol to minors remained the same over the past year, despite controlled purchase operations being stepped up threefold.
Police figures showed four premises in the Rotorua station's area were caught selling alcohol to minors in controlled purchase operations at on and off-licences in 2014, the same number as in 2013.
However, more than three times as many controlled purchase operations were performed last year, 54 compared to 17 in 2014.
Bay of Plenty Inspector Kevin Taylor said police continued to watch alcohol sales closely and were confident of the positive relationships they had with most alcohol outlets.
"We would like to believe that the partnership we have with the industry is fostering a more responsible and legal attitude to retailers' obligations under the Sale and Supply of Alcohol Act."
