A middle-aged woman on a zero-alcohol licence allegedly registered more than five times the legal breath-alcohol limit.
She was one of six drink-drivers apprehended by Dunedin police at the weekend.
Senior Sergeant Craig Dinnissen, of Dunedin, said the 40-year-old recorded 1400mcg per litre of breath at Queens Gardens, in central Dunedin, on Sunday.
The legal limit is 250mcg.
She was also on a zero-alcohol driver's licence, Snr Sgt Dinnissen said.
The woman was known to police.
Snr Sgt Dinnissen said the next-highest breath-alcohol reading recorded was 744mcg, from a driver on the Southern Motorway.
