The annual prizes are awarded to individuals and organisations from around the world who make notable achievements in the sciences, humanities, and public affairs.
The jury highlighted the All Blacks' "extraordinary sporting achievements over the years," and their commitment to "such noble values as solidarity and sportsmanship".
"The New Zealand team is the most successful national team in rugby union history," it said in a statement released when the All Blacks were announced as winners of the prize earlier this year.

Dagg said he couldn't believe the support they received and how many people love the All Blacks.
"It's amazing being over here and seeing that they follow the All Blacks and it's crazy to see. It's mindblowing to be from a little old country in New Zealand and people love the team."
Apart from hanging out with Spanish royalty, Dagg said he also met all kinds of amazing people from Nobel Prize winners to scientists and physicians.
"I'm trying to not sound like this little hori boy from Hawkes Bay," said Dagg.
"I'm trying to actually make them think that I know what I'm talking about and make them think that I understand what they're saying. I'm blown away. They're absolutely awesome people."
Dagg said they decided to perform the haka on stage after receiving the prize at the last minute.
"We just got up there and we did the haka and it just went silent and then people cheered. We've still got people coming up to us now and doing it.
"I'm very humbled and very grateful for the opportunity ... This is a 120 years of All Blacks rugby that I'm representing."
