"I am worried that it shows that the department places the interests of tourists above Kiwi trampers."
Siberia Hut would have a warden in residence during the entire peak season while a warden would only be based at Brewster Hut periodically.
Doc Central Otago operations manager Mike Tubbs said the only distinction between hut users would be that those who booked were guaranteed a bunk.
Last season, some trampers arrived at the huts to find out they had missed out on a bunk, Mr Trubbs said.
Because the booking system was a trial for the summer, Doc had not consulted other groups on the changes.
"What we do know is the huts have been oversubscribed and we don't believe having a booking system will create any sort of division or stop people from booking."
Trampers who found themselves caught out could still seek shelter in the huts, he said.
At this stage there were no other viable options available to help ease the demand on the huts.
A decision on whether the two huts would remain on the booking system would be made after the end of the summer season.
