Roa gets around on a farm bike, but recently bought a horse.
"Having a horse can be handy in winter when the tracks get a bit slippery. It's also a quieter way of handling the stock," she said.
Roa grew up in Hamilton. She got her start in the industry at Waipaoa Station, an hour's drive north of Gisborne.
"By chance I heard about Waipaoa's two-year cadetship. I attended the open day and it opened my eyes to the agri-food sector and endless opportunities within it," she said.
Roa was one of five accepted into the 2017 intake.
"For someone new to the industry I couldn't think of anything better than doing a cadetship," she said.
"Over my two years at Waipaoa Station I was exposed to all aspects of the industry. Our fencing and dog handling tutors were some of the best in the business."
Cadets are trained in all aspects of livestock handling and husbandry, and feed budgeting.
Skills taught in the classroom are able to be applied out in the paddock. Cadets graduate work-ready with several qualifications.
"When I started there I knew that sheep and cows ate grass and that was about the extent of my farming knowledge," she laughed.
Over the past two-and-a-half years Roa has worked hard to expand her skills and knowledge.
In May, she was named the winner of the 2019 Ahuwhenua Young Māori Farmer Award.
The announcement was made at a gala awards function in Gisborne attended by 600 guests including the Minister of Agriculture.
The Ahuwhenua Young Māori Farmer Award is designed to recognised talented up-and-coming young Māori farmers.
"Winning the award has been an amazing experience. It's been a great way to get my name out there and will look good on my curriculum vitae (CV) when I want to step up to a manager's position," she said.
As part of the award, Roa went to the Fieldays with AgResearch and attended a dinner focusing on disruptive technologies in the agri-food sector.
She was encouraged to enter the awards by her mother.
"I submitted my application two days before entries closed," she said.
"I was nervous about entering and putting myself out there, but then I realised I had nothing to be afraid of, so I gave it a go."
Lead judge Peter Little said Roa exemplified all that is good about young Māori who are making successful careers in the primary sector.
"Kristy has shown great commitment to her work, excellent leadership and will do a great job as a role model for other young people contemplating a career in the agribusiness sector," he said.
As part of the awards process Roa got to go on a two-day study tour with the other two finalists.
"It was extremely beneficial. I got introduced to a number of industry professionals. I really enjoyed the leadership and goal setting course run by PrimaryITO," she said.
It's not just soccer that brings Roa into Gisborne after work. She's been a member of the area's growing NZ Young Farmers club since 2017.
