"I love playing for Auckland, the Blues and the All Blacks," said Mealamu, who now has a half-century of international caps behind him.
"For me, the best way to show my commitment to continue playing rugby in New Zealand was to sign until the end of 2011.
"I believe it's an honour to play for the All Blacks and it would be very special indeed to play at a Rugby World Cup held in our country.
"Also, my wife and I believe the best place to raise our young family is right here."
The 29-year-old joins the likes of Richie McCaw, Dan Carter, Ma'a Nonu and Andrew Hore in committing himself to his national side at a time when a number of high-profile All Blacks are already playing overseas.
Mealamu is highly regarded in New Zealand and both his country and province are glad to see him remain with Auckland and the All Blacks for the foreseeable future.
"He is a leader in the All Blacks, respected by his peers and a key influence for younger players as well and we are delighted to have him re-sign with New Zealand rugby," said NZRU CEO Steve Tew.
"Keven is one of the most respected players in the game today, both at home and abroad," added Auckland Rugby and Blues CEO Andy Dalton.
"He represents what is great about the game of rugby, on and off the field. We are extremely proud to have him in our union and franchise and welcome the continuance of our partnership."
