Multiple people will appear before a Taranaki Rugby judicial committee after a serious brawl at a club match in New Plymouth.
The fight erupted after the final whistle of Spotswood United's last-minute 17-15 win over Tukapa at Sanders Park, Westown, on June 1.
It is understood rugby players, management, executive members of the clubs and supporters became involved in the violence. Another smaller brawl followed while players shook each other's hands.
The Taranaki Rugby Football Union (TRFU) and New Zealand Rugby (NZR) have been investigating the incident and players believed to have been involved were stood down from last weekend's clashes, TRFU community rugby manager Cole Brown said.
A number of people will now appear at rugby judicial hearings, which are being held behind closed doors, on Tuesday and Wednesday evening.
In an emailed response to questions about how many people would appear and whether they were players, coaches, managers or spectators, the TRFU said it would not disclose the names of those involved while the proceedings were taking place.
However, the TRFU said "multiple" people, representing both clubs, would be appearing and the union's independent judicial committee was responsible for dealing with acts of foul play.
The committee was very experienced and used to the judicial process, the TRFU said.
A rugby operations advisory committee, which includes a selected number of club representatives, was set up to handle any discrepancies/clarifications relating to club and secondary school rugby and would also be involved in the hearings from a competition point of view, the union said.
The outcome of the hearings is expected to be released on Thursday.
Brown has previously said the union and NZR were taking the situation seriously and the violence was a "rare and isolated incident".
The NZR Black Book states players, clubs or people involved in misconduct could face fines, be suspended for a period of time, be expelled from the competition, be given exclusion orders from matches or having any involvement with any teams playing matches, or be suspended from involvement in rugby coaching or administration.
Brown said teams could lose points as a consequence of the incident, which could prove costly as both were in the top three at the time the brawl occurred.
