Because I know I've got at least one friend who's interested in ghost towns, abandoned buildings and suchlike. I was driving through Orepuki today and got a couple of pictures of its (largely closed and derelict) CBD. (This is for values of "CBD" which include "about five shops on the old main street").
Will try to get something written up about the history of Orepuki in the next few days. Until then, there's Wikipedia.
