Parents, spectators and officials were horrified by the incident at the Papatoetoe Sports Grounds that occurred 10 minutes into the second half.
One parent, who did not wish to be identified, said that the player was walking towards the goal posts when he turned around and "gave the ref the finger", before running at him.
"The ref had his back turned and was blindsided by the boy who dropped him to the ground," the witness told TVNZ.
"There was a bit of a scuffle on the ground and then the player punched the referee."
Auckland Rugby Referees Association referee manager Smudge McNeilage said the referee was not physically injured in the attack, but was "certainly affected".
"He was been resting at home, he has certainly been affected by the event."
Ms Gundmundsson said the union received an official complaint about the incident on Saturday, and it was forwarded a complaints review officer.
A hearing overseen an independent disciplinary committee was scheduled to take place tomorrow, but may be delayed because of a separate disciplinary process being taken by Papatoetoe club.
The committee - made of about half a dozen people from different professions including the law fraternity - does not comment to the media, but its decision would be released through the rugby union.
It was understood a hearing would involve the referee association, the player and his parents, as well as witnesses from both teams, and could carry a lifetime ban for the boy, said Mr McNeilage.
Ms Gundmundsson said: "While it is important that Auckland Rugby does not intrude on the independence of the Disciplinary Committee we have extended an offer of support to all of the parties involved."
The disciplinary committee was responsible for evaluating all red cards issued to player, and had only dealt with one other complaint classified as more serious than a red card this season.
