Australian Stephen John Dartnall, 30, was stopped by police at 12.15am yesterday in Arthurs Point Rd.
He recorded a breath-alcohol level of 718mcg. The legal limit is 250mcg.
Dartnall won $9511.15 for his performance in the NZ Open at The Hills -- leaving him ranked 388th in the world.
He was convicted and fined $700, with court costs $130, in the Queenstown District Court yesterday.
Dartnall, representing himself, told Judge Tony Couch there were no excuses.
"This is something I don't condone at all. It's just terrible. I feel horrible for doing it."
Dartnall, who confirmed he had the funds to pay a fine immediately, was due to fly home to Australia at 4.15pm yesterday.
Sergeant Ian Collin said the golfer gave police officers no explanation for drink-driving, simply saying he was "trying to get home".
