On November 25, John Levy wrote to minister Eugenie Sage asking for the "very important health issue" of only two toilets, one at the start and one at the summit on the 16km return, to be addressed.
In the past year Doc recorded 81,350 people had walked the track, an average of 222.8 people a day.
"If the Mt Roy track was a restaurant, cinema or any other business in Wanaka, the Queenstown Lakes District council would require 47 toilets, not just two," Mr Levy said.
On December 16 Mr Levy received a reply from Ms Sage, in which she acknowledged "inappropriate toileting is unacceptable and of concern" but it was a national issue for Doc and not restricted to the Roys Peak track, she said.
"Encouraging behaviour change of our visitors requires a multi-agency approach across New Zealand ... there was a significant focus [last year] on promoting responsible visitor behaviour, which had a significant reach and impact," she said.
Trying to change tourist behaviour was "asinine", Mr Levy said.
"It is like saying we only have one toilet at the cinema or restaurant and everyone can just hold it until they get home."
Mr Levy has lived next to the Roy Peak track for nearly 10 years and last year he installed electric gates to stop hikers knocking on his door "all the time" asking to use his bathroom.
Recently, he saw a very intoxicated woman get out of a car and defecate in front of his front fence.
Mr Levy said he was also concerned about the speed and the volume of traffic on Mt Aspiring Rd. He said his children had seen a head-on collision one morning when they were waiting for the school bus.
"I don’t think anyone is against tourism, but this is the poster child of not managing tourism in a safe way or failed tourism policies," he said.
Doc acting operation manager Anita Middlemiss said four extra amenity staff had been employed over summer to maintain tracks, toilets and amenity areas around Wanaka and the Haast Highway.
At least two of the rangers were working each day, she said.
