As a *G status holder, you don't need a second carrier on the ticket to check in an extra bag in Economy (not counting Seat Only) but you do in Business?
I just checked NZ's baggage policy and they have indeed updated this under Gold benefits to include a 4th bag wording. Not sure when they made the change but still it's inconsistent with *A policy as *A website mentions nothing about having to involve more than 1 carrier and no other *A carrier does it.
