Dunedin police say they will be stepping up patrols to target anyone drink-driving home from end-of-season sporting group break-ups after 13 intoxicated drivers were apprehended this past weekend.
Acting Inspector Craig Dinnissen, of Dunedin, said all 13 drivers blew more than the old drink-driving limit of 400mcg per litre, meaning they will be heading to court.
``You can see why we're a bit disappointed,'' Insp Dinnissen said yesterday.
In 2014, the breath-alcohol limit was close to halved, down to 250mcg of alcohol per litre of breath.
Readings between 250mcg and 400mcg do not result in a criminal conviction, but yield a $200 fine and 50 demerit points.
Blowing over 400mcg results in court action.
Insp Dinnissen said the drink-drivers were caught throughout Saturday and Sunday all across Dunedin, and it was unclear what was behind the number of impaired drivers.
``Sometimes we can attribute it to sports clubs but we haven't done enough analysis at this point to see where their last drinks were.''
Those attending end-of-season sports break-ups needed to be aware that they could expect a heavier police presence targeting drink-drivers, Insp Dinnissen warned.
