That did not impress SAFE campaigns director Mandy Carter.
"At every single rodeo we see abuse of the most vulnerable of animals," she said. "In calf roping, weeks-old calves are forced to endure being chased, wrenched off their feet by ropes, slammed to the ground, then have their legs roughly tied together. Even worse, at the Mid Northern Rodeo they were goaded with painful electric shocks before even entering the arena.
"This kind of treatment of those that most need our protection cannot be allowed to continue. MPI must take urgent action to prohibit rodeo events, starting with calf roping."
Three formal warnings under the Rodeos Code of Welfare had led to the closure of the Huntly Rodeo, after officials stated that they could not guarantee the safety of the animals at future events, in 2014, she said.
Last year the MPI confirmed that seven rodeos had breached the Code of Welfare in the 2014/15 season, with numerous breaches in the following season. The ministry was still investigating complaints from 2016/17.
Lynn Charlton, from Anti Rodeo Action NZ, said the ministry was refusing to issue a warning to someone who had been shocking steers at the Warkworth rodeo claiming the footage wasn't clear.
"We disagree," she said.
"They're just hanging out one rodeo offender when many of them should be receiving these warnings."
Ms Carter said the images supplied to the MPI from the Mid Northern Rodeo included young calves being shocked with an electric prod while confined in a chute.
"Rather than the MPI relying on volunteer investigators to film and report cruelty to animals, we need urgent action to stop it happening in the first place," she said.
"The only way these animals will properly be protected is if rodeo is declared history.
Rodeo is inherently cruel. It's clear that people involved with rodeo are simply unable to even uphold the most meagre animal welfare regulations, so there is no alternative to a ban.
"Animals suffer for the entertainment of a minority. History shows that eventually these activities won't be tolerated by society. The repeated breaches of the Rodeos Code of Welfare, and this most recent warning, show that the regulations fall well short in protecting animals. The only real solution is a rodeo ban, with an immediate end to calf roping being a top priority."
