Koli Sewabu played for Manawatu for the 2006 and 2007 seasons, playing 9 games. He began his rugby career as an outside back but changed to a No.8, a move welcomed by his former mentor Buck Shelford due to his tackling ferocity and clinical play. After the Turbos, Sewabu played for multiple teams in Europe and his form earned selection into the Fijian national side.
