Sheep carcases are still being dumped on Hastings' streets.
Children had to walk to past the latest pile of dumped offal and skins on their way to school this morning.
The remains were found outside the main gate of the Te Kura Kaupapa school on Stock Rd, Flaxmere.
Police were frustrated at what was becoming almost a daily occurrence.
Flaxmere Community Constable Greg Andrew said police and the Hastings District Council were removing animal remains "just about every day" from roads on the outskirts of Flaxmere.
"Stock theft is becoming a major problem in this area.
"It is impacting heavily on farmers who are losing money very quickly and it is turning rural Flaxmere into a dumping ground.
Mr Andrew said some people may be turning a blind eye to what was going on. Black markets for meat or any other product were illegal and those running them could face serious consequences, Mr Andrew said.
"Likewise, if you are caught buying stolen meat or in possession of it, the penalties are high."
Police are urging residents to be on the lookout for any signs of illegal stock theft or slaughtering, which includes scattered wool or blood around a section, in garages or in vehicles; meat hooks or butcher's knives hanging up around properties; excess meat in freezers and fresh mutton smells around a house.
Anyone with information about the thefts should contact Mr Andrew on 06 8310700 or information can be left anonymously on Crimestoppers 0800 555 111.
