A female junior rugby coach, who pushed a referee after a friendly match on Saturday, is the subject of a complaint with the Otago Rugby Football Union.
The incident was believed to have occurred on Saturday, on the first day of the season, in what was a friendly round.
A bystander, who watched the game, said the coach was on the field, encroaching over the sideline for most of the game, yelling at the referee and players.
She came on to the field at the end of the game when the pushing incident occurred.
Otago Rugby Football Union referee education officer Jim Thomson said an official judicial process was under way and, because of that, he could not comment.
