Wellington - Loose forward Sam Cane signed on to stay with the All Blacks until 2021 on Monday, in a deal the world champions described as "a major coup".
The 25-year-old has played 49 Tests and is part of the All Blacks' leadership group, captaining the team on two occasions.
Cane, who also committed to the Chiefs' Super Rugby team, said he still had the drive to succeed at Test level.
"To re-sign was ultimately an easy decision for me, while the security of a long-term contract is great for me at this point in my career," he said.
"Even though I've been in the All Blacks for five years now, there is still heaps more I want to achieve in the black jersey."
"The deal is a major coup for New Zealand Rugby," the All Blacks said in a statement, adding that Cane was just the second All Black to commit through to 2021.
