Tamanivalu is the first Fijian player to join the Flying Fijians following the change in World Rugby eligibility rules in November 2021.
The squad also includes 16 players from the Fijian Drua, who will feature alongside other Super Rugby Pacific and Europe-based stars for their country.
“It’s very exciting and a real honour for us to present the first Flying Fijians squad of 2022 to the Fijian people”, Flying Fijians Coach, Vern Cotter said.
