She said the father was yelling and swearing as other parents stepped in to defuse the situation.
Yesterday, Howick Hornets club chairman Bruce Campbell said he reported the incident immediately to the Auckland Rugby League.
"Yes, the [Howick] father has grabbed his kid and dragged him down and said, 'Now you punch him'," he said. "It's inappropriate behaviour and we will be dealing with it."
A meeting was held on Tuesday night to discuss the incident.
"We've obviously got some very concerned parents ... Obviously this father, this is the way he's been brought up. It's pretty clear that he doesn't know that he's doing wrong.
"The boy knew that this was not the right thing to do. It's not something that he was comfortable with. We've got to break the cycle."
He said the father had been banned from all games "for now".
Mr Campbell has organised for the Ministry of Social Development's It's Not OK anti-violence team to hold two education sessions at the club - which the father will be expected to attend, among other anger management programmes and treatment.
"Where this particular parent is concerned, he's not allowed to attend any games going forward. We're going to put him through this programme and try and educate him.
"Obviously if that doesn't work, he won't be able to attend any games, ever, which would be a shame. I'm going to meet with him in the next couple of days and just lay out what needs to happen ... A life ban would not be out of the question.
"We want the young fellow who had his nose punched to continue to be a part of enjoying sport, and part of that, I think, is having his dad come along to watch him. So we need to try and help the guy out here.
"We think the first instance is to try and educate. You need to know this stuff. It's good for our game and it's good life skills," he said.
The Papakura player's mother was happy with the steps taken to address the situation.
"I just hope he [the Howick player's father] can learn from this. This could have turned into a really dangerous situation," she said.
Auckland Rugby League committee member Evelyn Brooker, who was at the domain when the incident happened, said the organisation would work with both clubs to resolve the matter.
A spokesman for the Papakura Owls commended Howick on their reaction. "Howick dealt with it really swiftly and appropriately."
