Kosi, a Mangare East junior from New Zealand, came through the Warriors system before being part of the strong Warriors reserve grade Premiership and State Championship winning team before joining South Sydney. After being unavailable in the trials, he made his South Sydney senior grade club and premiership debut in the 2026 Round 3 clash against Western Suburbs at the Central Coast Stadium. After suffering a long term injury, he was given a opportunity and sat on the bench before making his South Sydney first grade premiership debut in the 2026 Round 10 clash against Cronulla-Sutherland at Stadium Australia.
Kosi is a powerful outside back with a large frame and an imposing presence on the wing. He is a strong finisher with confident carries and genuine power in contact. Kosi brings speed, strength and the ability to break tackles out wide.
