He said seeing the mess made his blood boil.
There was red paint on the scaffolding tower to be used by the Sky camera crew and banners on the tower were also tagged.
A new scoreboard was also covered in red.
But with the help of the school caretaker and a sponsor and facilitator Deb Mair, the offending paint was gone by the time the cameras rolled.
"This is such an opportunity for our outstanding young players to get exposure to talent scouts."
Ms Mair, of Wild Haggis, said there were also a number of businesses on Bank St that had been tagged with red as well as the school's gym. She managed to get a special gel that made the removal of paint easier.
"We all wanted it to be right and didn't want to give these idiots any television exposure. We all pulled together and scrubbed it all off. It was our chance to showcase our rugby talent and showcase the fact we can hold an event like this in Whangarei."
A crowd of more than 300 watched the action unfold as did thousands more viewers on television without a trace of red graffiti.
Whangarei Boys' High School were the eventual victors 22-15.
And feedback from Sky commentators was positive with them saying they had not seen a match with such intensity and grit for a long time.
