IIRC, the whole trip to NZ fell through because of lack of funds. It was just him and two of his followers others who hiked at least part of the Appalachian Trail.

Along the way, Andy did successfully manage to get the pair who were with him to marry. I think there were several posts about the trip/wedding on his Tumblr, and possibly some discussion about it on FW, FW Reports, maybe FFA and/or SF_d.
