The group made a similar call before last year's event and announced it was planning to stage a protest at the CHB showgrounds.
However the protesters were a no-show and their boycott call appeared to backfire, as the biggest crowd ever turned out for the bull riding event, which was attended by a vet and the SPCA.
SAFE campaigns manager Marianne Macdonald said last week's footage was evidence of the "severe stress" the bulls were put through at rodeos and bull riding events.
"This is animal cruelty purely for the entertainment of a minority." She said a 62,000-signature petition presented to a New Zealand Parliamentary inquiry into rodeos last year was evidence that New Zealanders wanted to see an end to rodeo.
CHB A&P Association president Chris Menzies responded last week by saying that rodeo was a sport, not just entertainment, and SAFE had no scientific evidence to back up its claims.
"All the scientific studies undertaken in Australia and the USA have found there is no undue duress on animals competing in rodeos," he said.
He said last year's parliamentary inquiry by the Primary Production Select committee had found no reason to ban rodeos and did not make any recommendations to further improve animal welfare.
"And [the Ministry for Primary Industries] has produced a welfare code for rodeos which we abide to," Mr Menzies said.
"With reference to bulls being riled up and electric shocks from prodders, these are not allowed within the code - but they are used by SAFE to try and stir up emotion."
Mr Menzies said he took issue with SAFE's tactics and was concerned at the wording of last year's petition.
"Would it have been devoid of emotional rhetoric? I doubt it."
As for the 62,000 signatures on the petition, he said that equated to only 1.73 per cent of the population.
"Once again, a small minority ruining it for the majority."
However he whole-heartedly agreed with SAFE's stated aim of stamping out the "bullying" of animals.
"But why is it that SAFE uses these same tactics to bully our sponsors and supplier with vindictive emails?" he said.
Shane Bird, from Parklee Bucking Bulls who is also vice president of the NZ Rodeo Cowboys Association, dismissed SAFE's claims as an attempt to create controversy.
"It seems SAFE are beating the same drum, which hasn't been getting the results they want.
"Despite all their claims, there is not a single piece of scientific evidence to show that animals suffer at rodeo-bullriding events.
"In fact, a study conducted on the bucking bulls at the Calgary Stampede found the bulls actually enjoy being in that environment."
