Mike Minor, Michael Shea, Noah Elliot and Nicole Roundy all topped the pile on a day of banked slalom competition.

For Minor, it was a second victory in two days as he also won the men's SB-UL class yesterday at the lower level Southern Hemisphere Cup.

He completed the course in a time of 1min 8:04sec with Australia's Simon Patmore clinching silver in 1:08.66.

Bronze went to Zhuo Chen of China in 1:09.15.

"It feels amazing to have won," said Minor.

"We all have found it pretty challenging out there today. 

"I had a great first run with my fastest time. 

"This is our first qualifier for the Pyeongchang 2018 Paralympic Winter Games so I could not be happier."

Shea won gold in the SB-LL2 category with a final run of 59.00.

Australia's teenager Ben Tudhope clocked 59.28 for silver and New Zealand had something to celebrate on home snow when Carl Murphy won bronze in 1:01.21.

"It was great fun out there and I have always enjoyed more of an Alpine snowboard set-up," said Shea. 

Elliot's gold in the men's SB-LL1 saw him share the podium with bronze medal-winning compatriot Mike Schultz.

The winning time was 1:06.95 as Japan's Daichi Oguri split the two Americans in 1:07.79.

Schultz finished in 1:08.06.

Roundy won the women's SB-LL1 in 1:19.58 as China's Qiaorong Pang clinched the women’s SB-UL title in 1:26.23.

The pair were the only athletes in their class.

Australia's Jonay Badenhorst matched Minor by making it two victories in two days.

She added to her Southern Hemisphere Cup win by winning the women's SB-LL2 in 1:10:52.

Cassie Cava of Britain won silver in 1:18.52 as American Brittani Coury snatched bronze in 1:20.68. 

The competition, part of the Audi Quattro Winter Games NZ, was the first major event on the road to the Pyeongchang 2018 Winter Paralympics in March.
