"I cannot believe what I'm hearing coming out of Britain at the moment. This is the biggest thing in rugby outside of the Rugby World Cup," Fitzpatrick said. "The Lions are phenomenal. We should not even be discussing [the tour being the last].
"It is all very well talking about that if you are 12,000 miles away, and I understand the arguments in terms of a global season. But this tour is what rugby is all about.
"I love the professional game and everything about it, but we need to be a little bit old-school occasionally. The Lions are very much part of our history and the fabric of what we are.
"I have never seen Eden Park like it was last week - a sea of red for an All Blacks game, which was bizarre. It says a lot about the Lions' supporters and how good they are."
Current All Blacks captain Kieran Read also endorsed keeping the Lions alive on Friday.
"I don't think that [killing off Lions tours] will happen," Read said. "It has just been so exciting being around the country over the last couple of weeks and seeing the supporters from both sides. The fans are so passionate about the game. I'm sure it will continue."
