The 34-year-old sit-skier claimed the country's first medal at these Games with bronze in the downhill event. He finished 11th in the Super G.
He was New Zealand's flagbearer at the opening ceremony, having recently recovered from a dislocated right shoulder.
Peters had been pursuing split second improvements at these Games after missing out on gold by 0.47s in the giant slalom four years ago at Sochi.
Auckland University's wind tunnel was employed to help him search for better aerodynamics with the help of High Performance Sport New Zealand's Goldmine programme and Christchurch-based designers Dynamic Composites.
The result was a one per cent difference to the drag on his sit-ski that he hoped will take him one step further at these Games.
