My wife and I did a 3 month backpacking trip through Equador, Peru, Bolivia, Chile, Patagonia and Tierra del Fuego last winter on a $100 a day budget, which is ample for most of SA.(Chile and Argentina were the exceptions however. We plan a 2 month NZ trip. Can we do it on $100 a day for both of us? We are active "trampers", mountain bikers, canyoneers(I work as a guide here in Zion Park, Utah).
