Flanker Richie McCaw was named as Tana Umaga's successor as All Blacks captain on Saturday.
McCaw had been the overwhelming favourite for the post
Coach Graham Henry had hinted McCaw was the favourite to take over the post and made it official at the weekend.
"As well as a great honour and privilege, it is a big challenge to captain the All Blacks," said McCaw.
"Along with the other team leaders, I hope we can keep improving on the success of the last 18 months and play some exciting rugby."
McCaw has previous experience of leading his country, first taking over the role as a 23-year-old against Wales in 2004.
He also led New Zealand against Ireland on last year's Grand Slam tour when Umaga was rested.
His national coach said: "It's a natural step for Richie McCaw to take on the captain's role.
"He has been an All Black since 2001, he is a world class player, and he has led the team well in previous Tests. He has also been a highly successful captain with the Crusaders and with Canterbury."
McCaw made his All Blacks debut in 2001 against Ireland and has played a total of 36 Tests.
