More than 10,000 people have signed a petition to stop Saturday's New Zealand International Rodeo at Claudelands Event Centre.
But the rodeo looks set to go ahead amid calls from Save Animals From Exploitation (SAFE) and a Hamilton animal activist that rodeo is a dated blood sport and should be banned.
Rodeo organiser Darryl Tombleson says there have never been any injuries to animals, or people, in his rodeo in the five years it's been operating.
"We have vets on site and structures in place to ensure there aren't any injuries. I appreciate their opinion but we are pedantic about ensuring the animals' safety," said Mr Tombleson. "I've never understood the mentality of people jumping up and down without knowing the facts."
SAFE campaign manager Mandy Carter said rodeo had "nothing to do with New Zealand".
