A sports psychologist says Aaron Smith's latest indiscretion is ridiculous schoolyard behaviour that is not tolerated in the larger arena.
The All Blacks halfback will be facing disciplinary action over an encounter with a woman at a Christchurch Airport toilet, the day after the test against the Springboks in Christchurch three weeks ago.
Registered psychologist Sara Chatwin said Smith had brought shame on the sport with his actions.
"He's yet again brought the spotlight onto the sport for the wrong reasons," Chatwin told Newstalk ZB.
"It is really unfortunate because as Kiwis we love our rugby, we love our sport."
Situations like this cast aspersions on rugby and the people who played it, she said.
