Hi there!
While researching my November Stay on the South Island, I've learnt that we get 10% off the ****ing expensive huts,campsites on the great walks.
BUT you need to book at a DOC office so they can check the FMC membership(*).
Cheers, Achim
(*) the DOC staff was unsure, finally they wanted a backcountry hut pass with a FMC membership number...
