Talent scouts believe the Sacred Heart boarder has what it takes to become a household name over the next few years. But Tupou, who was born in Tonga, is not a New Zealand passport holder and will not be eligible to play for the national secondary schools team later this year.
The New Zealand Rugby Union (NZRU), in conjunction with the New Zealand Schools Rugby Council (NZSRC), has decreed only players with New Zealand passports can be picked - a decision that has upset Sacred Heart.
"I think it is a naive stance," principal Jim Dale said. "If there are talented kids like Daniel and they are deemed to be good enough, they should be picked - they should be given the opportunity. Daniel has been here in New Zealand since late 2010 and he's a wonderful kid. I'd hate to think that he'd be lost to another code or to another country who could be more accommodating."
As recently as last year rugby administrators made exemptions for boys who didn't have passports as long as they had signed contracts with New Zealand provincial rugby unions. At this year's annual meeting, however, the NZSRC confirmed no exceptions would be made in 2014, meaning New Zealand will reject one of the most promising players in the country.
Mr Dale is hopeful the decision would be reversed if Tupou's form continues. His intention was to stay in New Zealand and pursue a career in professional rugby. Signing a provincial contract would also strengthen his case.
"He is definitely on our radar," Auckland Rugby Union high performance director Ant Strachan said.
The NZRU and NZSRC said the eligibility ruling stopped players missing out to boys who may not commit to living here beyond their schooling.
