Yes ... usually expected *A NZ Biz award availability between NA and AKL has been cut drastically, but I don't think most believe it to be true.

I can't say I always do exhaustive searches up to my target travel time (Apr-May); however, they have been pretty thorough. What I've noticed:
- haven't seen a single 773 seat (LAX-AKL, AKL-LAX) since late last year
- seen a few 744 seat via SFO about a month ago that disappeared quick
- a few 772 YVR-AKL seats come and go (ex 2/25,26)
- 763 seats via LAX and SoPac/HNL to AKL are typically available

If my plans finalize and the stars align I'd probably be more likely to find availability that worked on *A UA F via SYD
