Ioane's list of international honours include an Olympic Games in rugby sevens, selection for the Māori All Blacks and he was also the captain of the New Zealand secondary schools team. The 2017 World Rugby breakthrough player of the year is now into his seventh season with the All Blacks, where he has played 56 tests with 48 of those in the starting XV.
All Blacks head coach Ian Foster was in charge of the backs as an assistant when Ioane earned his first selection in 2016 and has witnessed immense growth in him as a player and a person.
"Rieko is a young man with a massive amount of international experience. So to have his commitment through till the end of the World Cup is pleasing for us. And hopefully for longer after that."
A member of the Blues under-17 and under-18 development sides, Ioane has become a key contributor at Super Rugby level. Playing for the Blues on both the wing and in the midfield he has 45 tries to his name, making him a fan favourite.
"We're looking forward to another big season for Rieko, he's playing some of the best rugby of his career," said Blues head coach Leon MacDonald.
"Rieko has been with the Blues since he was a teenager, he's been through our system and is part of our Blues family, so to have him contracted again is great news.
"He is a leader on and off the field, and is now in a position to pass on his knowledge and experience to our younger squad members. We are looking forward to him continuing to be a world-class centre for the club."
