Reece's fast-track into the All Blacks continued after a sensational 15-try Super Rugby season that followed a domestic violence incident previous year which nearly derailed his career.
Electric winger Sevu Reece will start for the All Blacks in their Rugby Championship clash with Argentina while four more uncapped players are lined up on the bench. "The team is a mixture of experience and raw enthusiasm". "We'll continue to nail the details further in training throughout the week so that we are bright, clear and excited to play with real intensity come Saturday", Hansen said.
As expected, Sonny Bill Williams sits out the match after not fully recovering from a hamstring issue, with Anton Lienert-Brown and Ngani Laumape starting in the midfield. "We need to find out about Sevu and some of those other selections we've made".
Captain Kieran Read is among the Crusaders being rested, with flanker Sam Cane handed the skipper's armband for only the third time in his 61-Test career.
There is a sense among Argentine rugby fans that it could finally be their year and the addition of five European-based players to their squad has given the Pumas an extra boost.
"When you look at Rieko not playing, it's a reflection of the fact that we already know that he's a very, very good test player", Hansen told journalists. "Their players will have taken a lot of confidence and self-belief from the Jaguares Super Rugby season... they will see this game as a massive opportunity to make a statement".
