Nanai made his first ventures in senior rugby in the Auckland region of New Zealand, representing them in sevens rugby as well as winning the World 10s Championship with the Blues.
His performance saw him called up to the Auckland ITM Cup team in 2014 and he made 5 appearances without scoring any tries.
Through that performance, he earned a spot in the Blues wider training group for the 2015 Super Rugby season.
Nanai made his Super Rugby debut in 2015 against the Cheetahs, in Bloemfontein.
Ahead of the 2018 Super Rugby campaign, Nanai has made 38 appearances, scoring 13 tries. He will remain in Auckland until the end of 2019 after signing a new deal in August 2017.
In February 2019, Nanai became Worcester Warriors' fourth new signing for the 2019 season and will play in the Premiership for the first time.
