Magic Travellers Network is promising savings of up to NZ$306 (£120) on the Discovery and Navigator pass.
Until August 31st, passengers will be able to get a third-off the pass' price which allows them to hop-on and hop-off at hostels around the country.
A spokesperson for the coach operator said: "By listening and speaking to backpackers in New Zealand, we have identified that a main concern in the current climate is the ability to purchase a well-priced product, without compromising on the quality of the experience."
According to the Magic Travellers Network, the firm's coaches allow travellers to get involved with activities including hiking in National Parks and bungee jumping in Queenstown.
Drivers also offer an accommodation and activity booking service on-board so backpackers can plan their itinerary more easily.
