They will be attempting to become the first New Zealanders to medal in PyeongChang, and only the second ever to medal in the country's Winter Olympics history.
Wanaka Snowboarder Zoi Sadowski Synnott, 16, is one of the youngest of New Zealand's 21 athletes who are competing at the Pyeongchang games.
Sadowski Synnott beat out fellow Olympian Carlos Garcia Knight to win Snow Sport New Zealand's athlete of the year award last year.
2017 was a big year for the snowboarder, winning her first snowboard world cup - becoming just the third Kiwi to do it.
Sadowski-Synnott along with the rest of the snowboard slopestyle field advanced to today's final by default after the qualification round was cancelled due to strong winds at the Phoenix Snow Park venue.
This means all 27 athletes will compete in the final and each competitor will have two rounds instead of three.
The cancellation follows an earlier decision yesterday to postpone the final of the men's Alpine skiing downhill.
Skier Alex Robinson will also be competing for a medal today.
Robinson, 16, is the youngest ever New Zealander to compete at the Winter Olympics.
The Queenstown skier will be competing in the giant slalom, which is one of Alpine skiing's more technical events.
"I am so happy to be given this opportunity and am super-excited to be competing at my first Games so young," Robinson said.
"I don't mind being the youngest; I quite like it because I find it a bit more of a challenge."
Last year, the 16-year-old won the Snow Sport NZ's Breakthrough Season Award.
