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."
