The former Wanaka man has been missing almost a month, since launching from a point near the town of Eureka on August 22.
Search team member Amanda Jane reported on an American fundraising site Mr Oroc’s Ozone Zeno wing was found tangled around bushes about 16km from his last known GPS point, in an area known as Nine Mile Canyon, south of Eureka.
His harness was missing.
Ms Jane said the wing was reported by two people passing through the area who recalled seeing "a parachute billowing in the wind".
"The unrolled chute is indeed James’ wing," she said.
The immediate area was being searched and people around the world scanning computer satellite images were focusing on the area via website http://9mile.xcskies.com.
Mr Oroc is a prominent figure in world paragliding circles. He took up the sport while living in Wanaka.
