Heaphy Track in Kahurangi National Park
"The Heaphy Track is located in Kahurangi National Park at the north-west corner of the South Island. [...] Translated its name has a number of meanings, including ”treasured possession”. In places it is an untracked wilderness; elsewhere a network of tracks lets you explore wild rivers, high plateau alpine herb fields, and coastal forests.
The Heaphy Track is the longest and most diverse of the Department of Conservation (DOC) Great Walks." http://www.southernwilderness.com/heaphy-track
