After many calls nd outright refusal to refund NZ2/NZ2 I filed a DOT complaint. I received my DOT reply that in essence required AIRNZ to refund about 2 days before AIRNZ publicly conceded the issue. I rang and was given a refund which landed in my account 2 days latter. The required response from AIRNZ to the DOT arrived about a week after, stating that they were required to refund and on checking had already done so. Guess that had to follow thru so as to comply with the DOT.
