"At the same time, it emphasises the players' thoughts about how they feel about the All Black jersey and for that matter their franchise. A lot of players made the decision to stay and try to win a championship for their franchise.

However, Hansen added: "Everyone will come back and review the process and we'll learn some lessons as we always do. It took us a while to win a World Cup [after 1987]. We've just got to make sure we don't paper over things - we've got to look at it honestly and genuinely as a rugby-playing group, the sevens, the All Blacks and the Rugby Union itself, and see how we can do it better because it's an opportunity to showcase rugby from New Zealand."
The New Zealand men won only one match at the Olympics - against Kenya - losing to Japan, Great Britain, and finally, Fiji. Their victories in the world series this year have been built on their size and physicality, and starring roles from Akira and Rieko Ioane, but the brothers struggled to find their feet in Rio and it appeared other nations had done their homework on Sir Gordon Tietjens' team.
Hansen said the men's team would "rue" their opening loss to Japan, a huge shock, but disagreed that New Zealand's top players might be ordered to attend the next Olympics in Tokyo.
"When you do that you're taking away peoples' choices of what game they want to play... that's not the way you run your business or the way you treat your employees."
