Just got confirmation of refund received (by my TA) for 3 x PAX, AKL - IAH - ATL then ORD - AKL return, booked discount premium economy - special fares. Was due to depart 23/5 and return 29/5. This after being declined 3 times. Finally been approved post the announcement 29/4 re US DOT regulations.
Air NZ cancelled these flights and offered no alternative.
Great success.
