The All Black loose forward Steven Luatua will captain the Blues for the rest of the Super Rugby season after regular skipper Jerome Kaino was ruled out with injury.
Luatua was selected with an eye to the future and with the full endorsement of Kaino and 170-Super Rugby game veteran Keven Mealamu.
"I was a bit in shock and left for words. I am really humbled and at the same time gutted about the injury to Jerome," Luatua said.
"Growing up as a kid in the region, this is something you aspire to. We still have Kevie but he believes this is the best direction to head in so I will give it my best shot."
Coach Sir John Kirwan said while the side will miss Kaino both as a player and a leader, it was an excellent opportunity to promote Luatua.
"We recognise Steven as a future leader in the club. The experience will help Steven grow as a leader and player and it will be a great support for Jerome in the coming years," Kirwan said.
The 13th-placed Blues have lost two All Blacks in Kaino and Charles Piutau to injury for the rest of the season.
