He said since posting about it on his Facebook page he had reports of people dumping at other sites including Tikitere and Dansey Rd.
Mr Sturt said the most recent rubbish dumped on Mountain Rd included general household waste and old building materials.
He felt sorry for tourists going up Mountain Rd - "some of the most beautiful parts of Rotorua" - and seeing the rubbish.
"It's just an ongoing problem.
"They think it is their right to dump it."
Mr Sturt said there had been cameras at Mountain Rd on and off for about five years but that didn't deter people.
"It's just disgusting and it's a health issue."
Mr Sturt said he would like to see something like a rubbish sheriff investigated, whose sole job was to tackle the issue.
Rotorua Lakes Council's transport and waste solutions director, Stavros Michael, said the council's contractors frequently monitored Mountain Rd where the illegal dumping was "unfortunately problematic".
"We are currently trialling dedicated surveillance equipment elsewhere. If these trials are successful we will deploy this technology at Mountain Road and will pursue prosecutions of offenders. We are planning a major clean-up of the areas in the near future to prepare for surveillance programmes."
Keep Rotorua Beautiful chairman Grant Gibson said rubbish dumping was a community problem which had been going on for years.
He said Mountain Rd was a problem area, but there were also other bad areas.
Mr Gibson said without having someone stationed up Mountain Rd 24/7, it was up to the community to help monitor and report suspicious behaviour - something he conceded was difficult given much of the dumping happened in the middle of the night.
"It's one of many places. If you go along Tarawera Rd there is stuff over the side of the road... furniture and chairs, TVs, all sorts of stuff."
He said many of the dumping sites could only be seen by those walking or cycling and weren't visible when driving.
Mr Gibson encouraged those who did spot suspicious behaviour to note number plates and take photographs if possible - then pass those on to the Rotorua Lakes Council.
"Everyone in the community has to keep their eyes and ears open."
He said Keep Rotorua Beautiful was looking for committee members, and the more members it had, the more it could do.
