He had big wraps on him coming through at the Raiders. Thought he was decent enough on the field but obviously off-field stuff held him back and he retired at 26 due to mental health reasons. He did come back and play in the local league at one point, not sure if he's still around. Don't remember him having a younger brother and can't find any record of one at the Knights.
Same time frame as Mataora we had Paterika Vaivai who I had big wraps on coming through, and thought he showed a fair bit of promise in the 6 NRL games he got here, but he got himself sacked and then never kicked on at the Titans. Still playing regularly for Ipswich in QLD Cup.
