If you've ever been tramping in remote parts of the country there's a good chance you've used some of the huts and tracks provided.
But have you thought about who maintains them?
Permolat is a community group of volunteers that take the time to restore and preserve rundown huts so other avid trampers can use them.
Andrew Buglass started the group more than ten years ago, and it now has more than 200 members.
