"They have a small group of riders and they don't have the same kind of disposable mindset of, 'Oh, we can just fill it with another good rider,'" said Lyon Farrell, the Kiwi snowboarder who finished eighth in big air and 15th in slopestyle. "They don't have that depth. They really support their guys from an early age and build them up from a development side."
Though snowboarding and skiing tend to occupy their own silos, there's very little of that in New Zealand, which bundles all its resources under an umbrella that supports both sports.
Exhibit A of the benefits comes from the Melville Ives family, which produced 19-year-old twin brothers Cam and Finley. Cam is a snowboarder, Finley is a freeskier.
"Their dad and mom have been working with them since they were like 3 years old," Hetzel said. "They were the first kids on the chairlift every year. They came to us when they were about 12. They're singularly focused on snowboarding and skiing. That lends itself to doing very well."
While White, Kim and many more of the trailblazers of this sport at the Olympic level had only one event, the halfpipe, to amass their medals, the addition of slopestyle and big air in 2018 added new opportunities for countries, and athletes, to break through.
