Rotorua police, alongside Hamilton and Tauranga Traffic Alcohol Groups were out in force this weekend as part of Operation Tri-City.
The operation included running checkpoints across Rotorua, with 7986 cars stopped across Friday and Saturday nights.
Police have been working hard to remind road users to stay sober, alert, and safe this summer, but unfortunately many people still haven't got the message.
Across the two days, 42 people who police stopped were over the legal breath alcohol limit, with a number of these over double the limit.
Rotorua police area commander Inspector Anaru Pewhairangi said this was extremely disappointed and "frankly quite shocking".
