The quartet includes Wanaka's Adam Hall, gold medallist at Vancouver in 2010 and who will be competing at his fourth Paralympics in the slalom standing discipline.
Carl Murphy, a 38-year-old father of four from Wanaka, will contest the snowboard, in which he placed fourth at Sochi three years ago.
Sochi giant slalom silver medallist Corey Peters, of New Plymouth, is chasing more success, after three world championship second placings to go with his Sochi podium finish.
He made his debut in 2014 and was the only medallist across the Winter Olympics and Paralympics from New Zealand.
The team is rounded out by debutant Aaron Ewen of Auckland, who has nailed five podium finishes in international events this year.
Between them, the quartet have five world champion and two Paralympic medals.
"I have seen so much change and growth in Para sport both nationally and internationally since I competed at my first Paralympic Games in Torino 2006," Hall said.
"The Rio 2016 Paralympic Games was a huge turning point in New Zealand as Kiwis watched the team free-to-air on TVNZ and Attitude.
"With this also being the case for PyeongChang 2018 we encourage all New Zealanders to show their support and watch us in action on the slopes and be inspired to think differently about what disabled people can achieve."
