The future is moving closer for Dane Coles with the tyro All Black hooker asked to suit up for his first duel with the Springboks.
Coles' two starts in eight tests came against France as the selectors pondered the form, future and health of senior men Keven Mealamu and Andrew Hore.
All are fit for Saturday's clash between the unbeaten sides in the Rugby Championship but Coles has won the No 2 jersey ahead of his more illustrious teammates.
"We have a massive amount of respect for South Africa and have prepared accordingly,"All Black coach Steve Hansen said.
"The physical challenge will be huge, as it always is, and the team that executes their game with the greatest effectiveness, clarity and intensity will be the one that comes out on top.
"The whole All Blacks group is looking forward to this challenge as it will give us a great indication of what level our game is at."
Coles' selection is a play-or-perish approach, a chance to get a serious gauge on his progression as the All Blacks look long-term towards the next World Cup.
Age is posing a question about Mealamu's quest to last a further 2 years at the top while Hore is understood to be leaving the international game later this year.
Whatever the outcome for the two senior hookers, more have to be introduced to the All Black sanctum.
Coles made that jump on last year's tour to Europe after previous choices Hika Elliot and Corey Flynn were overlooked. They are still in the outside lanes, with Liam Coltman, Rhys Marshall and Nathan Harris linking up at team training sessions this season.
Meanwhile, Coles will get a Springbok welcome from Bismarck du Plessis, who is returning to test rugby after a year out with a knee injury.
It will be a great measure for Coles because Du Plessis is as rugged as any hooker on the world circuit and, like Hore, is a remarkably consistent menace in mauls.
A month ago there was a surprise when Coles was released to ITM Cup work, rather than the Bledisloe Cup bench in Sydney. The selectors explained they wanted to give him more match play and he was on the test bench for the last two internationals.
His sudden promotion against the Springboks will provoke even greater astonishment.
However, it is in line with other choices the All Black selectors made, like the promotions of Aaron Smith, Julian Savea, Beauden Barrett, Sam Cane and Luke Romano last year.
They continued that work with Charles Piutau, Francis Saili, Matt Todd, Steven Luatua and Jeremy Thrush in this campaign.
Blindside flanker Liam Messam is reinstalled for Eden Park after his hamstring strain and takes over from impressive newcomer Luatua, who will also cover lock from the bench.
"In selecting the team, there were some tough decisions to be made, none more so than between Liam and Steven," said Hansen. "In the end we have gone for Liam's extra experience and physicality, but we also know that Steven will enter the contest at some stage."
Cane will play his 10th test as a replacement for injured captain Richie McCaw and in midfield, Ma'a Nonu rejoins the backline after a week's rest for his ankle problem.
