Air New Zealand Air Points - Farecode for NZ

Hi folks,

I'm trying to use my UA miles to claim a reward ticket HKG<->AUC (business class) on NZ. And the system show me this:

Cabin class: C4 D4 Z4 Y7 B7 M7 H7 Q7 V7 W7
T6 L6 S6 G6

Could someone help me to understand which code is for Business Class reward? I think C & D are for the regular fare Business Class.

Thanks in advance!

Business class award code is "I". This doesn't show by default on most availability screens, however using smile67's excellent availability tool (the link to download it is in smile67's 3rd post on this page of this thread (http://www.flyertalk.com/forum/Forum1/HTML/009504-19.html) and selecting 'special classes' you can successfully search for I class on AirNZ.
