AB is the airline company in OW. AB Top Bonus is its FFP but it's no longer fully owned by AB. It was sold out to get cash.

"Topbonus is being sold to a separate legal entity named Topbonus Ltd. with its head office in Berlin. It will continue to operate the frequent flyer program on the basis of a commercial agreement with Air Berlin.

Upon close of the transaction, Etihad will own majority stake in the entity, with 70 percent hold, while remaining 30 percent will be owned by Air Berlin."

So, in a certain sense Ethiad told they don't match NZ* but perhaps Qantas or Cathay could be considered.
