Miscellaneous resources, none of which I endorse unless I specifically say so. Just one to start off this page…
Bushman Tours: An organisation with a variety of guides in New Zealand who do this casually on top of their day jobs.
Wilderness Magazine: I subscribed to their online and also print service when I came to live in New Zealand, and have found these to be very useful. The large and expanding database of trip reports is excellent, and there are also all sorts of articles on various aspects of tramping (hiking). You might find the online service is enough if you just want to find specific information. The gl0ssy mag is nice if you like to flick through articles of interests and look at pretty pictures.
