The Hawke’s Bay skier was the top Kiwi or Australian athlete across the two-day series.
"It’s great to win it and to defend my title," Hudson said.
"It has been a few years since we have been able to hold these races due to Covid-19, so it’s nice to have them back."
The achievement means Hudson (26) has qualified for a starting position on the World Cup slalom circuit for this coming northern hemisphere season.
"For me, going into the northern hemisphere season, it means I have secured my own spot on the world cup tour.
"I can start in bib 31 at Nor-Ams and Europa Cups and it also helps with my budget, as I get free accommodation at certain races.
"It really helps out, which is great."
Auckland skier Mikayla Smyth (17) was the fastest under-18 athlete from any nation competing in the ANC slalom, indicating the New Zealand talent pathway is deep in slalom ski racing.
The series will continue on Saturday with two super G races, followed by two giant slalom races on Sunday and Monday as the opening events of the Winter Games.
