Then these are the NZ mileage-earning booking classes (all at 100% with no minimum):
EC: U,E,O ("Premium Pacific Class")
EC: Y,B,M,H,T,Q,V,W
All other economy classes will not earn MP miles.
BTW, this info is found for all *A carriers in the UA forum on
this thread, linked in the FAQ Sticky

I know about the booking classes, but the NZ website doesn't let you do it that way. You can choose a variety of opaque categories like "unrestricted" or "no advance purchase". All of those options come up with a fare over $6,000, which is the usual ridiculous full fare economy.
I guess I'll have to call.
