Peters, who had already pocketed gold and silver medals at Beijing, completed his campaign with a DNF in the first run of the sitting giant slalom yesterday.
"The course was set really tight — some of the gates were set 23m, 24m," he said.
"When you’re on a 30m-radius sit-ski, it makes it a little bit trickier, just to try to get the ski to bend through those tight turns.
"I got rotated through the turn and the tail of the ski washed out. I’m disappointed as I know I can ski better than that and I didn’t manage to put it down today.”
Nevertheless, Peters is heading home to New Plymouth on a high with the medals he won in downhill (gold) and Super G (silver).
"We always work towards becoming a Paralympic champion. It took me 11 years, but I managed to achieve that goal.”
Young Wanaka-based skier Aaron Ewen was 23rd after his first run in the sitting giant slalom.
But he, too, had a spill in the second run.
Ewen, at his first Paralympics, gets one more crack in the slalom on Sunday.
All New Zealand eyes will be on double gold medallist Adam Hall as he tackles his specialist event, hoping to add to his career tally of four medals.
