Piutau was the top try scorer for the New Zealand Under-20s in their 2011 World Championship winning campaign. In 2010 he played for the Tongan Under 20 team and he was a member of the New Zealand Sevens team in 2011/12.
He was brought into the Blues squad to cover injuries at the tail end of the 2012 season and proved his skills are up there with the best in his two ‘match of the match’ appearances.
