Tuigamala, who works with former Manu Samoa player To'o Vaega, father of the Kelston 1st XV captain, said it was difficult to feel there was any justice.
"I'm befuddled. On what basis have they made this judgment? I don't think the committee has thought it through. I'm appalled by it."
He said members of the Vaega family were bitterly disappointed.
Former All Black flanker Michael Jones said the committee had to explain how it arrived at its decision.
"On the one hand you have a very severe punishment, and on the other a very lenient punishment.
"This has not gone down well from the outside looking in and communities need the justification."
The disciplinary committee delivered its decision after spending more than 10 hours deliberating.
Jones said disciplinary action was needed, but he questioned its severity.
"If they were looking for fall guys [for bad behaviour in rugby] then it needed to happen a long time ago and to those at a higher level who these boys look up to."
Kelston principal Steve Watt said the school was considering appealing against the bans and was "reviewing the options" open to it.
"Some decisions will be made after the weekend," he said.
Auckland Grammar headmaster John Morris indicated after the hearing that some students from his school could face further internal discipline.
He did not return calls yesterday, but wrote on the school's website that he had watched the video of the incident frame-by-frame.
"I am even more sickened by the level of violence I observed - it literally turned my stomach. There are no innocent parties in this.
"Some of our boys have to take responsibility for responding most inappropriately, regardless of which team started the fracas."
The suspended players have seven days from the time of the judgment to appeal against their sentences.
A member of the disciplinary committee, former detective senior sergeant Neil Grimstone, said last night that the bans were tailored to individual players depending on their rugby commitments.
"We were privy to a lot of things that are not in the public domain," he told TV One's
Close Up
programme.
"We've made our decisions on video footage other people have not seen."
