Kaino made successful return to the Blues in the 2014 season, being named as the team's captain for the 2015 Super Rugby season, taking over from fellow back-rower Luke Braid. Kaino played his 100th match for the Blues on 28 February 2015, but the Blues unfortunately lost 24-25 to the Cheetahs that day. Kaino's captaincy at the Blues did not last long, with hooker James Parsons taking over during the 2016 Super Rugby season.
