"These clowns take it upon themselves to lash out and paint an embarrassing picture for the game. With this punishment we want to show that we have the backs of our officials and won't tolerate this behaviour from anyone.
"These are volunteers and they are already few and far between, we need to show that we support them."
Mr Tamati said sideline and on-field behaviour was a major concern in this country and the incident exacerbated the notion there was a problem with people watching and playing sport being unable to control themselves.
"It's worrying that people aren't listening or taking notice, maybe the punishment that we are going to dish out will," Mr Tamati said.
The board met last night after consulting New Zealand Rugby League to discuss what action to take.
They made the unanimous decision that harsh action must be taken against the players involved.
Once all the official reports have been collected, the judiciary will make their decision on what the penalty will be.
"There should be a decision by the end of the week," Mr Tamati said.
