The pre-existing cost to stay at any of the sites has not changed.
The huts in Tongariro that can be booked online include Boyd, Blyth, Mangaehuehu, Mangaturuturu, Rangipo and Whakapapaiti.
“Your booking is adjustable, and it also means we can contact you if changes in track or weather conditions might affect your plans,” Smith said.
The huts will remain open to any visitors as emergency shelters.
“Backcountry huts are always unlocked and available as emergency shelter to any who need it, regardless of booking,” DoC visitor services manager Cameron Hyland said.
“Booking provides extra assurance to families and less experienced visitors.”
Bookings will be flexible to accommodate changes in conditions or travel plans.
Huts included in the Backcountry Hut Pass and Campsite Pass will remain available for online bookings.
DoC manages more than 950 huts across New Zealand. Fees to stay at the huts go toward their upkeep.
