Chiefs head coach Clayton McMillan said Ah Kuoi was a big part of the franchise.
“He’s a strong, consistent performer and has been outstanding for us in his time with the team,” McMillan said.
“He’s a big personality that adds a lot to the off-field culture, bringing abundant energy. His family have been a real ‘why’ for him and we are glad to have them continuing as part of the Chiefs whānau too.
“We are looking forward to seeing his continued development as a player and as a man.”
At NPC level, Ah Kuoi has made a home at the Bay of Plenty Steamers and he said he had big plans for this team.
“At the end of the day, I just want to win a title for this province and its people. That’s it.”
This week the Chiefs face the Blues in their final regular-season match, in what should be a Battle of the Bombays blockbuster.
