Hanson was given only a warning by the Metropolitan Committee when he appeared in front of the judiciary on Thursday night for his role in the incident.
But his club has decided to force Hanson to watch today's game between Dunedin and University A from another field.
He will not be allowed to have contact with the team either during the game or at halftime.
The incident occurred during Dunedin's game against Green Island at Dunedin's home ground, Kettle Park, a week ago.
Referee Liam Scanlon's report said the game was called off slightly early because of an incident which arose after a Dunedin player was tackled by a player not using his arms.
Hanson "stepped on to the field, pushed a player and said, `If I ever see you do that again ..."
Scanlon said the Dunedin coaches were so close to the ground that they were on the field of play before he had time to blow his whistle.
There were no ropes in place to keep management and supporters back, and he doubted the incident would have occurred if ropes had been in place.
The Dunedin club has difficulty roping off the beach side of the ground as there is very little room.
But it is looking at drawing a line halfway between the sideline and the retaining wall to guide where coaches should stand.
Hanson wrote a letter of "sincere apology" to the Metropolitan Committee, which governs club rugby on behalf of the Otago Rugby Football Union.
"I accept that it is not appropriate for any coach or spectator to come into contact with any opposition player during a match," Hanson wrote.
"[My] reaction ... simply wrapping my arms around and essentially stepping between an opposition player and our player ... was purely motivated from the perspective of care and concern for the safety of players."
Hanson said he spoke to the Green Island player immediately after the game to offer his apologies.
The ORFU said the Metropolitan Committee had decided a warning was sufficient punishment for Hanson, and the Dunedin club was now dealing with the issue.
Dunedin coach Ed Baker was suspended for two weeks in 2008 for abusing a referee.
Scanlon's report on last week's game pointed the finger at both Dunedin and Green Island management for their "abusive" behaviour.
