A match in Wanaka last Saturday ended in a brawl and police were called to the match, while a game last month between a side from Telford Polytechnic and Otago Boys' High School was called off early, after a fight involving both sides.
A hearing had decided letters would be written to Otago Boys' High School and Telford to reprimand the players on their behaviour that day.
Neither side would take any competition points from the game.
Otago Boys' was believed to be winning the game before it was called off.
Otago secondary schools rugby council chairman Mike Newell said he could not tell whether there was an increased number of unsavoury incidents, but generally he felt games were played in good spirit.
He admitted because of funding issues the secondary school grades below the Highlanders First XV competition did not have a set, easy-to-follow structure.
This led to games where teams of one age-group were playing against a side of a different age-group. School teams had been forced to play club sides.
Whether that had led to an increase in violent incidents he could not say, but the schools council was looking at a review to see what had worked and what could be changed.
The secondary schools competition used to get about $30,000 from the Otago Rugby Football Union to help run the provincial-wide competition.
But this had dropped to $10,000 this season because of the Otago union's financial troubles, and so costs and travel had to be cut.
The Highlanders First XV competition had recorded no instances of bad behaviour and the chairman of its competition committee, Des Smith, said he has been very impressed with the standard of teams in the grade.
He had not witnessed one incident and had been all around the region to watch games in the competition.
Otago Rugby Football Union operations manager Richard Perkins said he was disappointed to hear about the incident in Wanaka.
Perkins felt it was hard to say whether this season was any worse than previous seasons for violence on the field.
"It is not acceptable at all that this has happened but until we do a review at the end of the season we can't really compare this year against any other," he said.
Metropolitan junior rugby chairman Grant Degarnham said he had not heard of any bad incidents in primary school grades.
He felt the key was communication with club delegates making sure any problems were quickly fixed in their club's teams.
If the problem remained, it would fester and could become bigger than it needed to be.
The Otago Rugby Football Union could not provide information yesterday on the outcome of the hearing into the incident of the game between a Telford Polytechnic side and an Otago Boys' High School side.
The game was called off 20 minutes early after a brawl broke out between both teams near the sideline.
