Gee said to the Herald after his appearance it was the "silliest mistake I'd ever made".
Gee said on the night in question he had drunk three wines, however he said, "I don't normally drink wine."
Gee said Lawyers had suggested he could get off the charge due to his band profile, but the musician felt he didn't deserve any special treatment.
"I was very happy to plead guilty...I was very happy to put it behind me."
His message to others; "Don't drink and drive, it's a very simple lesson... it's just not worth it."
He said his day in court could have been the least of his worries.
"I'm just very thankful no one was hurt... silliest thing I've done, gross error of judgment."
Gee, 42, is the drummer, guitarist and one of the founding members of the Feelers which formed in the early 1990s.
His profile on the band's page cited that in his spare time he cooks, cleans, feeds the chickens and is currently teaching drums, bass, guitar and mentoring up-and-coming bands at the Auckland School of Rock.
