The Ministry for Primary Industries has charged a person over bobby calves abuse.
The ministry began an investigation in September last year, after receiving footage of what appeared to be abuse against bobby calves in the Waikato region.
The footage was released by animal welfare groups SAFE and Farmwatch.
The ministry has filed charges under the Animal Welfare Act at the Huntly District Court.
Spokesman Scott Gallacher said the investigation was ongoing, and the ministry was unable to comment any further.
