But former Lions great Barry John told Wales on Sunday: "The haka has been part and parcel of the All Black team for as long as I can remember.
"It's not menacing and players who face it either face up to it or just don't look. It would be sad if it went."
And fellow Welshman Mervyn Davies agreed, saying: "The haka is part of a tradition, part of a tradition of New Zealand rugby and also the surrounding islands.
"Yes, it is intimidating to the opposition, but from a personal point of view it was a way of switching myself on and focusing on the game ahead."
