Kendra Breen, of Alexandra, Angie Perkins, of Wanaka, and Liz Hore, of Tarras, will all contest the barrel racing events at the rodeo, which draws competitors from Australia, Canada, Brazil the United States and New Zealand.
A bull rider from England will also take part this year.
Women are not allowed to ride in the saddle-bronc, bareback or bull-ride events.
Last year, about 8000 people watched the events.
Mrs Breen and Miss Hore competed and Mrs Breen won third place.
The trio had been asked to compete in the invitation only event after they scored top places in the New Zealand events last season.
They will take one horse each and have been working on keeping their horses fit throughout the winter.
Mrs Breen has an arena set up at her property where they can practice barrel racing.
She will be riding Banjo, a 20-year-old that belongs to her father, Murray McMillan, of Mt Pisa Station.
Miss Hore will ride Clint a 14-year-old horse she has owned for six months.
She is also training a 3-year-old quarter horse called Dragonfly.
Miss Perkins is riding 18-year-old Ziggie, which she has borrowed from Mrs Breen as her horse Winkie is in foal.
Mrs Breen said they hold a barrel racing weekend around the region every couple of weeks, and other people who are interested in rodeo are encouraged to come along and have a go.
As well as practice she is also the person who takes all the entries for the rodeos around the country.
There are 32 in all, from Invercargill to Kaitaia over the summer season.
The three women travel to all of the rodeos to increase their points as well as living their day-to-day lives.
Mrs Breen is a wife and mother of three, Miss Hore is a nurse and Miss Perkins works on the farm.
So what drives these women to take part in what has traditionally been a male sport, and a rough one at that?Mrs Breen said the thrill of the competition drives her.
Miss Hore enjoys the speed and athleticism of the horses and what they can do.
"It's all over so quickly. There's just 16sec to prove how fast you are in each event, and you only have split seconds to react," she said.
