Tourism and commercial enterprise have been part of New Zealand’s outdoors for at least the last century. The Milford Track spent much of its history as a relatively high grade tourist attraction. For a time it was largely exclusive, and that only changed after an act of civil disobedience which asserted the public right to explore a National Park. Closer to my own home, the popularly known Southern Crossing route across the Tararua Range had its modern beginnings with an intent to attract tourists to the region by creating a tramping route, and providing huts for accommodation.
DOC’s mandate recognises this. Section 6 of the Conservation Act, which defines DOC’s responsibilities, states that DOC should foster the use of natural and historic resources for recreation, as long as it’s consistent with other requirements, and allow their use for tourism.
The distinction between recreation and tourism has become more important recently, though.
