Collins has represented New Zealand at Schools levels and has experience captaining the Otago Boys' High School 1st XV.
His call up at Otago saw him decline offers from Melbourne Storm and ITM Cup Premiership side Waikato.
October 2016 saw him earn his first Super Rugby contract with Auckland-based Blues side for 2017, a deal that was later extended beyond the 2017 season.
During the 2017 Super Rugby season, Collins made 14 appearances scoring two tries having been used mainly as a utility player.
At the end of the season, Collins' contract at Auckland was extended for another season, after being rewarded with the Club Rookie of the Year award.
