Doors began to open for him ahead of the 2016 season as Apisai was left temporarily as the Canes first choice No 2 and debuted in week one of the season against the Brumbies in Canberra.
Apisai started the first three games of the year and played a total of five matches in his first season as a member of the Canes senior squad.
