The Port Chalmers Community Board deputy chairman and Port Chalmers resident discovered a pile of dumped household rubbish opposite his home in Victory Pl about two months ago.
After a "horrific", "awful and very stinky" clean-up, he thought that would be the end of the story.
Until the next day, when he discovered another bag dumped in the same spot.
Once again, he removed the bag and disposed of it with his household rubbish in a Dunedin City Council-approved bag.
But the game continued. Rubbish would be dumped every one or two days and Mr Walker would remove it.
During the past month he has cleared about 40 bags of rubbish and his household has gone from putting out a council rubbish bag once every six weeks, to once a week.
"It intrigues me that someone is going to the effort of putting all their ... [rubbish] in a bag and driving around here to dump it," he said.
Fed up with what appeared to be a "habitual" situation, and how someone was getting away with disposing of their rubbish illegally, Mr Walker contacted the council two weeks ago.
Council solid waste contracts supervisor Peter Moroney said council contractors were "patrolling" the area and a "no illegal dumping" sign would be erected next week.
Anyone caught dumping rubbish illegally could face a fine of up to $500, he said.
While the dumper was "persistent", most people who carried out such activity slipped up in the end.
"We will catch you," he said.
