This link from www.spcacertified.nz details how to become SPCA accredited.
An estimated 3.8 million beef cattle are farmed in New Zealand. The Code of Welfare for sheep and beef cattle sets out minimum standards required for their care.
SPCA Certified has animal welfare standards which exceed the minimum legal requirements laid out in the Code of Welfare.
SPCA Certified standards also require beef cattle farmers to have an animal health plan in place which is regularly updated with a veterinarian. In addition, all farms are audited, not just annually, but also randomly at least once a year. Under the Code of Welfare, animal welfare audits are not required for beef cattle.
