Local vets, breeders and the SPCA have slammed Hawke's Bay residents carrying out cruel and illegal horse castrations in the region.
A Ministries of Primary Industries investigation found seven people doing or commissioning the illegal procedures here and in Gisborne recently.
Only qualified veterinarians or undergraduate students supervised by a professional are allowed to conduct the significant procedures.
MPI Wellington and Taranaki District Compliance Manager Mike Green said investigations were conducted between March and May after a tip-off from the public. "It appears to be a practice that is well ingrained in the culture of the farming and rural community of the wider East Coast area with this service being utilised by many large station owners despite them knowing it to be illegal," he said.
Local vets and the SPCA said it was dangerous and cruel to castrate horses unprofessionally. Vet Associates Hastings Director and Veterinarians Michael Newall said animal welfare was severely jeopardised by illegal practices.
