Animal welfare officers have euthanised 180 cows and calves found starving and near death on a West Coast farm.
The Ministry of Primary Industries is considering laying charges under the Animal Welfare Act over alleged neglect at a leasehold farm in the Lake Brunner area.
An investigator who inspected the farm on August 28 found several cows dead and the rest of the 940-strong herd in "various stages of starvation".
Local veterinarians, a farm consultant and additional animal welfare officers assessed the cows.
They were found to be in such an emaciated state that they were unlikely to survive more than a few days.
