However, Hansen disagreed with the suggestion of haka fatigue, saying it means a lot to this group of players.
"I don't think it's been used too much," said the All Blacks head coach before the team departed for Australia ahead of the first Bledisloe Cup test of the year.
"It's part of the tradition and I found it interesting that someone like Kees (Meeuws) would say it's being used too much. When he was there he thrived on it.
"We don't use it any different than we've ever used it. It's part of the commencement of the game and it means a lot to this group. They understand all about it, we understand it's not for anybody else other than ourselves and we draw a lot from it."
All Blacks selector Grant Fox also expressed support for the haka, saying the desire and commitment from the players remained strong.
"It's a very traditional part of what we do," Fox told Radiolive. "At the end of the day, part of it is obviously going to be about the boys and their desire and attitude toward it, which is very committed to it I've gotta say from what I've [seen].
"Some teams would probably like to see us not do it so often because they think somehow it gives us an advantage. I'm not convinced it does that, it's just a very traditional part of what we do prior to a match."
