People around the world are searching for former Wanaka paraglider James "Kiwi" Oroc (Johnson) without leaving their computer screens.
Mr Oroc was last seen on Saturday in Nye County, southwest of the town of Eureka, in Nevada.
While friends and family are in the area using aircraft to search for him, others are poring over satellite images on their computers.
Search co-ordinators in the United States are suggesting those wanting to help search for the missing paraglider log on to http://9mile.xcskies.com.
The site provides high-resolution images of the land around the last GPS signal from Mr Oroc near Nine Mile Peak in Nevada’s Antelope Range.
It provides a means for those searching the images to carry out a meticulous grid search, and to report any sightings that might help locate Mr Oroc.
The hope is someone might spot Mr Oroc’s white, blue and grey Zeno paraglider or his white or possibly red reserve parachute.
The search and rescue teams are advising the area has white rocks and bleached dead trees and that open terrain has been thoroughly viewed by ground teams.
They suggest those willing to search concentrate on land covered with thick, very dense, shrubs. More than $77,000 has been raised online to help pay for the physical search.
Mr Oroc is a prominent figure in world paragliding circles.
He took up the sport while living in Wanaka.
In a recent update, search team member Amanda Jane said an extensive search near where his Garmin GPS device last put out a signal found no sign of him.
"This is great news. The team believes he flew on, not realising he was disconnected from his Garmin/flight deck until later.
"The search continues to expand its reach on ground and in the air."
