"New Zealand are world champions and enjoy a historic win rate of 77%, the closest thing to guaranteed success a sponsor of a major sport could hope for," Bryn Anderson, head of Brand Finance's sports marketing, said of the All Blacks' corporate appeal.
"The All Blacks are a sponsor's dream off the field too, renowned for their fairness, good-sportsmanship and disciplined behaviour."
However, Anderson believes the All Blacks and NZRU may fail to fully capitalise financially on their World Cup victory.
"Adidas extended its deal to 2019 while the fees for broadcast and content rights have been agreed with Sky TV until 2020, meaning two key commercial deals cannot be renegotiated for over three years," he said.
"In addition, the NZRFU have in the past taken a conservative approach to establishing new deals, cautious of the sense of ownership that many Kiwis feel for their national team.
More needs to be done, Anderson says, to help raise the All Blacks' profile around the world and maximise the commercial opportunities that their brand presents.
"There is no reason they couldn't establish dozens of global, top-tier partnerships in the same way that football clubs such as Manchester United have done," he added.
"A willingness to expand and segment commercial partnerships will be important. So too will be increasing the visibility of the team outside of major tournaments by staging exhibition games, particularly in the US, or even locating competitive games in key growth regions, just as the NFL now does in the UK.
"Brand Finance's analysis suggests that the All Blacks could command a US$500 million brand within a decade."
