The Waikouaiti Rodeo Club is preparing to paint the town pink again.
The CRT Tough Enough To Wear Pink rodeo will be held at Waikouaiti on February 5.
Last year's rodeo raised nearly $9000 for the New Zealand Breast Cancer Foundation.
It was hoped to have another successful event with people enjoying "a fun day out for everybody" and seeing the skills of the cowboys and cowgirls.
The proximity to the beach made it a "stunning" location, club member Henrietta Purvis said.
People have been encouraged to buy polo shirts - bright pink for women, and black and grey with a logo for men - to help the cause.
All the cowboys and cowgirls will be wearing pink.
There were a lot of cowboys heading down from the North Island, as it was getting close to the national finals in Te Anau on March 26 and there were a lot of titles "up for grabs".
"It's one of the last rodeos, so they need to win points," Mrs Purvis said.
Other southern rodeos include Mataura on January 29, Southland on January 30, Outram on February 6 and Lawrence on February 12.
