"Nah, I never get nervous," he said.
His father, Tama Tauariki, said golf was his son's best sport and he did rodeo for a different reason.
"This is just to harden him up," he said with a laugh. "He's a bit soft, too much golf, bro."
Mr Tauariki said he had four children and three grandchildren who all enjoyed the rodeo, learning mainly on their farm in Ngakuru.
"When we have stock they get a bit of a ride but there are more golf balls on the farm than anything else at the moment."
Mr Tauariki also competed at the rodeo, in the high-profile roping competitions.
Late in the day, a 24-year-old man was taken to hospital after falling from the bull he was riding. The bull stomped on the man's lower abdomen and he was taken to hospital to check for any damage, St John Ambulance Rotorua operations team manager Darryl Stretch said.
The annual rodeo circuit will take riders such as the Tauariki family up to Warkworth Rodeo on Tuesday and the Far North Rodeo on Wednesday.
