His lawyer Stephanie Burlace said Tehuia-Webb was apologetic and had made a bad choice on the day.
"It's obviously the result of a family member calling attention to it," she said.
"It's not something he's known by the family to do at all and that's why they sent a clear message that it won't happen again."
Judge Philip Crayton sentenced Tehuia-Webb to 40 hours community work, six months supervision and disqualified him from driving for six months.
"They were concerned about you, no doubt for your own safety," he said.
"Your reading was extremely high. Two and a quarter times the criminal limit for driving."
