If the sand is a coastal beach then the tags should be changed to:
Chatham Islands Imported: 6/5 - Glen
RP: i wonder if this includes beaches? perhaps natural=beach if so?
HB: ... but is it exclusively at beaches? there are inland dunes in some places. Probably want to check/revisit list this later to answer that question, although I think natural=sand does a good job of matching the layer name already :).
Glen: Most of them are beaches but a significant number are not. I've imported as natural=sand and have added a cleanup task to go back and selectively edit the layer.
HB 18 Aug 2012: Tagging approved by Glen and seconded by me.
