Glad you've found somewhere good.

If you want to send away, or if you come south of the Bombay Hills, you can try Imagelab - they also have a shop in Chch. There is another professional lab right opposite Imagelab (name escapes me at the moment) in Wellington, though I've never used them myself.

From what I've been told, Imagelab handles all the E6 and LF processing for several of the camera shops in Wellington.
