The huts are located on the Mt Somers Track, a 26km long walk aimed at intermediate to advanced walkers and trampers.
Both serviced huts, the 26-bed Woolshed Creek Hut and the 19-bed Pinnacles Hut, are manned by hut wardens over the summer months.
The walkway is popular with families and offers options for day trips, single overnight trips, and two-night experiences.
The online booking system has led to more people enjoying this unique location as they have the certainty a bed will be waiting for them at the end of their hike, said DOC senior ranger Murray Thomas.
Walkers were able to pace themselves and did not need to rush to be the first to the hut.
Trails were also becoming less overcrowded as people forward-plan their trips based on bed availability.
"The huts received an astonishing 173% increase in bookings for November, when compared to visitor numbers for November 2018.
"Woolshed Creek Hut was nearly fully booked for every Saturday until Christmas and Pinnacles Hut was also busy," he said.
Some 729 people stayed in both huts in January, compared to 420 people for the same month in 2019. More than 670 of the January visitors were New Zealanders, and 474 were adults.
