The tournament also highlights growing interest in college league around the country, with huge demand for spots in the competition.
"For schools like Greymouth in the South Island, Francis Douglas from Mid Central and Wesley in Counties Manukau, this will be one of their first experiences at this level of competition," NZRL football manager Tony Iro said.
"Hopefully, their presence will be inspirational, not just for them but for other schools considering their future participation at this tournament."
