Sean, the owner of this site lives up in Auckland and has/had one of these as a project to get working but ended up throwing in the towel from memory. Not really useful info but thought I'd comment anyway :P
I really hope you find a good home for this, and hope it stays in NZ too. There's not enough people here shooting big stuff. Personally, I have no use for it. The largest I shoot is 4x5 and considering I don't have my own place there's no possible place I could put it. But good luck with finding somewhere for it.
