Several dozen people against rodeos protested outside the Warkworth rodeo on Tuesday, following the death of a bull last week.
The bull was euthanized at a Gisborne rodeo after dislocating its leg.
Direct Animal Action's spokesperson Apollo Taito says the group wants to see clear action taken against rodeos.
"We're quite confident that if we see the worst aspects of rodeo removed, it pretty much will be the end of rodeos in New Zelaland, because they're quite dependent on those aspects of causing distress and terror on animals."
He says tail twisting, rope-burning, flank-straps, the use of animals under 12 months and electric shocking needs to be banned.
Apollo says Direct Animal Action has had enough of needless deaths at rodeos.
