New Zealand's Tranz Rail offers a pass that can save you money on train, bus and ferry trips. The "Best of New Zealand Pass," good for 180 days, works on a point system. A 600-point pass, for instance, is good for $600 worth of travel in New Zealand currency--but costs only $420 in that currency. The New Zealand dollar is worth about 57 U.S. cents. ATS Tours in El Segundo, telephone (310) 643-0044, and Newmans South Pacific Vacations in Los Angeles, tel. (800) 421-3326, sell the passes.
