James "Kiwi" Oroc (Johnson) was last seen on Saturday August 22, just after 2pm, in Nye county, southwest of Eureka, Nevada.
Search team member Amanda Jane said "we know that if Roc found water — which there are numerous sources in the area — then he is still alive".
The "Kiwi hunt" was now being managed by volunteers on the ground after local counties and sheriffs officially withdrew from the search.
So far, more than $90,000 has been raised through an online website to help pay for the physical search.
Yesterday, the family of Mr Oroc also offered a reward of $US10,000 (about $NZ14,800) to the person who found him.
