Constant rain may have contributed to a quiet weekend in Dunedin's student quarter, police say.
Officers were prepared for a busy time on the first weekend of students being back in town.
Extra staff, including team policing units and the traffic alcohol group, were on duty around the student area in North Dunedin, Senior Sergeant Steve Aitken said.
But the weekend was quieter than expected.
"Sometimes we went in to pubs and nearly doubled the numbers.
"I'd say it was the rain."
Seven people were arrested by the drink-driving team, but the number of other arrests was lower than normal for the weekend.
Extra police staff would be on duty around North Dunedin during orientation week, which began yesterday.
Team policing units would be working again at the weekend, Snr Sgt Aitken said.
