Tuivasa-Sheck 'stoked' to get an All Blacks start against Japan
The 29-year-old abandoned a flourishing rugby league career at the end of 2021 in a bid to land a place in the New Zealand squad for next year's World Cup in France.
Despite some in New Zealand feeling he has not been used enough by the All Blacks this season, Tuivasa-Sheck is happy with his progress.
"This is another massive chapter in my learnings for this year," the fleet-footed centre told Stuff Media.
"I've made the crossover from rugby league, and the ultimate dream is to be part of that World Cup squad next year.
"It was just a bonus to be called up this year, and I'm stoked to be getting a test match start. I've got to enjoy every moment and opportunity I can."
But for his decision to switch codes, Tuivasa-Sheck would undoubtedly be playing for his country in a rugby league World Cup match against Ireland in Leeds later on Friday.
Tuivasa-Sheck said being parted from his family during the COVID pandemic, when his New Zealand Warriors league club relocated to Australia, had been a key factor in giving the 15-man game a go.
"I made the decision I was going to risk all or nothing and try my luck at rugby union," he added.
"I'm just so happy to line up with a World Cup that's there to be chased. I back myself to chase it and then return back home to be with my family."
Tuivasa-Sheck will win his third cap against the Brave Blossoms at Tokyo's National Stadium on Saturday in a makeshift centre partnership with Braydon Ennor.
He is expecting Japan, who have never beaten the All Blacks, to throw the ball around and has no doubt what his job will be in the opening match of New Zealand's season-ending tour.
"My biggest strength is being able to beat a player one-on-one, take the ball forward and gain momentum," he said.
