The 25-year old joins the club on a reported three and a half year deal worth $500,000 a season.
Warriors chief executive was delighted for the club to add a player of Nikorima’s calibre.
“We couldn’t be more excited to secure a player of Kodi’s calibre, especially at this stage of the season,” George told the Warriors website.
“We’ve been patient in watching the player market for some time. Peter O’Sullivan and our recruitment team have done a terrific job in securing Kodi, who will certainly add value to our club.”
Nikorima was equally thrilled to join the club and the direction it is headed.
“I’m really excited about coming to the Vodafone Warriors and moving to Auckland,” he said.
“It’s a new challenge after being at the Broncos for so long but I’m looking forward to working with the coaching staff and the players. I like the direction the club is heading in and it will also be good to be around a lot of familiar faces, both the coaches and team-mates.
“I also want to thank the Broncos for the opportunity they gave me to develop as a player. The club has been a huge part of my life and I’m grateful for the way so many people supported me there.”
