Younger brother of All Black tighthead Ofa Tu'ungafasi, Isi looks as if he will follow his brother's footsteps and represent the All Blacks having already represented the New Zealand U20s at the 2015 U20 World Championship.
He made his first start provincial in Auckland's premiership semifinal against Tasman at Eden Park in 2015, replacing the vastly more experienced Sam Prattley who was ruled out after injuring his neck.
He won the World Championship with New Zealand in 2015 and will look to earn a Super Rugby contract in the coming seasons.
Tu'ungafasi was called into the Crusaders squad as injury cover during the 2019 Super Rugby season and went on to make his debut.
