Police were still investigating the large-scale brawl and it was unknown if charges would be laid.
Tangaroa College principal Ngaire Ashmore said a hearing would take place on July 14 in front of the ARU's disciplinary committee.
The committee, made up of independent panellists, does not comment to the media but it was understood its decision would be released through the ARU.
Ms Ashmore said no students had faced disciplinary action at the school as a result of the incident.
"We are working our way through a process and really trying to understand exactly what happened and how it was able to happen," she said.
She said the school has held meetings with the Auckland Secondary Schools Rugby Union, police, Otahuhu College and students.
Ms Ashmore said all spectators who attended Saturday's game were welcome back to watch future games.
Otahuhu College principal Neil Watson said the school was also working with police, Tangaroa College and match officials.
The ARU has refused to talk about the incident until both police and its own internal processes are complete.
