Police say they are "extremely disappointed" by the number of people caught drink driving during a 24-hour operation targeting alcohol-related crime.
The annual, trans-Tasman, Operation Unite campaign saw 43,916 drivers pass through a breath alcohol checkpoint.
While the final results are still to be revealed, police said they were "left aghast" by the number of people who continue to get behind the wheel while impaired by alcohol.
Alcohol Harm Prevention manager Inspector Ben Offner said: "We're extremely disappointed with the high number of people who were detected drink driving. One is one too many, but there were plenty more and they should all know better."
"As we lead into the busy Christmas period, this should be a wake-up call for all New Zealanders, to make alternative transport arrangements if they plan on drinking. We all have a responsibility to ensure our mates, family and whanau get home safely and make responsible decisions on the road."
