Auckland Rugby is investigating claims of violence in club rugby, including one of an 8-year-old boy being shoved and another where a match official says he was punched.
This comes after the Herald revealed last month police plans to have cops on the sidelines of school and age-grade matches in a bid to curb violent and abusive behaviour.
In the first incident, an 8-year-old Pakuranga player was allegedly at the receiving end of violence. Miles Hayward said his grandson was pushed in the back by a parent at an under-9 game against College Rifles.
"I feel that parents are getting away with too much aggressive behaviour towards referees and players," he said.
"He ran on and took exception to how his son had been tackled, he ran on the field and pushed my grandson. I'm bloody angry at this guy.
