The number of animal welfare complaints the Ministry for Primary Industries has investigated on farms in the Bay of Plenty is on the rise - with three farmers prosecuted over the last three years.
Data released shows the ministry has already received 24 complaints in 2015 compared to 21 in 2014, while 11 of those complaints over those timeframes happened on dairy farms.
A Ministry for Primary Industries spokesman said not all of the complaints were substantiated cases of animal abuse and often involved light or lame cows.
The complaints covered a broad spectrum and were resolved promptly but a full investigation would be mounted if any offending was discovered, he said. There were four warranted officers in the Waikato/Bay of Plenty region, with two based in Tauranga.
The news comes amid public outrage at bobby calves being beaten to death on secret video footage recorded by animal rights group Farmwatch that aired on TV One's Sunday programme earlier this week.
