This is probably a tad early, but I thought I might as well test the waters to see if anyone has any knowledge of the field. I'm a Landscape Architect, professional member of the Hong Kong Institute of Landscape Architecture so getting my NZ professional membership won't be a problem (the NZ, HK and Australia intitutes have reciprocal agreements). I've investigated things remotely via the intertubes, but there's only so much that will tell you. So, anyone here know anything about the field?
