The latest putrid find was discovered by two recreational walkers on Centre Rd, off Highcliff Rd, on Saturday morning.
Jane Cox, an Otago Peninsula resident, told the Otago Daily Times she was walking with a friend when the pair noticed a fetid smell emanating from a bank beside Centre Rd.
Investigation led to the discovery of three animal carcasses - two calves and one deer - in one spot, and the remains of another calf dumped further down the road.
The bodies were already decomposing but appeared to have been dumped there, together with other items of rubbish, earlier the same morning, Mrs Cox said.
"They had been obviously butchered for someone's freezer and then dumped.
"It's a completely disgusting sight," she said.
Police and the Dunedin City Council were alerted, and council contractors Fulton Hogan arrived shortly after noon to remove the remains.
Mrs Cox said she was worried the area's proximity to the city made it an increasingly popular dumping site.
"I walk with my friend on Centre Rd quite a lot and it's becoming a bit of a dumping ground.
"This [animal carcasses] is a bit bigger."
The landowner, David Lyttle, said when contacted the area was a popular spot for people wanting to dump rubbish, garden waste - including invasive weeds - and, occasionally, animal remains.
"It happens pretty frequently actually.
"There's somebody constantly dumping garden waste there ... we actually saw them [once], but we were too far away to get a registration [number].
"They dumped a whole lot of bottles and they were gone."
Mr Lyttle said his neighbours faced the same problem, with any spot with enough room for a motorist to pull off the road and quickly empty a car being "hit pretty often", he said.
The council was "reasonably prompt" in sending contractors to clean up dumped material, but more action was needed to catch and prosecute those responsible, Mr Lyttle said.
"Sometimes we have got rego's [vehicle registration numbers] and there doesn't seem to be any particular follow-up or outcome."
Mrs Cox said she also regularly discovered rubbish dumped on the roadside while walking in the area, although it was the first time she had seen, and smelt, animal remains.
"They dump by the side of the road and then they are away.
"They think it's out in the country and nobody will notice, but we do.
"We notice it not only because of the sight, but the smell of it."
Mrs Cox feared the dumping could threaten the viability of a proposed multiday walking track spanning Otago Peninsula.
"It's not going to happen if it's a pig-sty. We have got this wonderful natural resource, but we are spoiling it because we are slobs and stupid," she said.
