I haven't been able to pin down anything from the NZ survey, despite the claim I seem to have made in the wiki.
In the thread,
"Speculating about Camp Zero," Andrew McKenna said some stuff had been found:
"Talking with a few of the Nikumaroro Veterans, the impression has been that the Arundel buildings were farther up the Nutiran shoreline. We found the remains of some old structures just a bit south of the NC wreck, and inland about 50 meters - see the screen shot. The assumption was that they could be the remains of the Arundel buildings based upon the building materials, but I don't think we've ever actually established that. Could have been colonial era buildings, we just don't know for sure.
"This area is somewhat coincident with the NC survivors camp, and the NZ survey camp, so there is a lot of overlap it would seem.
"That doesn't rule out Arundel buildings down on the N side of the lagoon passage as Richie indicates. I spent some time in that area and did not see anything that look like the remains of shacks, but we did see ruins further N."
