"That's some really bad behaviour there."
In another alleged drink-driving incident, police were called to a crash in Cargill St, Dunedin, at 12.15am on Friday.
A 25-year-old woman was picking up a friend when she crashed into a parked car.
Dinnissen said she tried to flee, but her car's engine seized.
The woman claimed to have drunk three beers over three hours, but had a breath-alcohol level of 504mcg, double the legal limit.
Dinnissen said "504[mcg] is a bit more than three beers".
At 10.45pm on Friday, a 27-year-old learner driver came to the attention of police after running an amber light at the intersection of George and St Andrew Sts, in Dunedin.
The man was found to have a breath-alcohol level of 772mcg, Dinnissen said.
"Drink-driving is a constant."
