A driver was allegedly almost five times the new drink-drive limit when stopped by Queenstown police on Sunday.
The Central Otago woman, 34, provided a breath sample which returned a reading of 1188 micrograms of alcohol per litre of breath say police, when stopped near Frankton roundabout, State Highway 6, at 1.30am.
Officers in a patrol car had noticed her swerving down the road.
Drivers with more than 250mcg but less than 400mcg in their system are ticketed under new rules that came into force in December. Those with 400mcg or more go to court.
Three-and-a-half hours later, at 5am, police stopped a 29-year-old Swedish woman on the same stretch of road, after a taxi driver reported her poor driving.
