There will be New Zealand's premier Parklee bucking bulls and "exceptional" bucking horses taking the centre stage.
"We're hoping for good weather and lots of people, that will be the icing on the cake," Rerewhakaaitu Rodeo Club president Clarry Church said.
"She's going to be a big celebration, we've got all the cowboys from across the country and the next generation of young Churches."
Among them will be Merv Church Jr, who won the Professional Bull Riders event in Christchurch last month.
Clarry Church said the success of the family in rodeo was down to the patriarch, Merv Church, who won 30 national titles to become the country's most decorated cowboy.
"We aspire to be like him, it's in the blood.
"The younger generation are coming through now and they're all pretty sharp."
This is the first rodeo on the calendar with other events in Gisborne, Opotiki, Taupo on December 29, Warkworth, Kaitaia and Whangarei.
