NZ reminding me today why I dislike dealing with them.
Booked AKL-YVR-AKL-TUO Business Class last week for my mother, booked on NZ's website.
Went to cancel it today as she wants to change dates and with the sale, net savings are ~$1,000. Ended up doing a credit voucher for $0 fee

Cannot cancel online, cancel button is inop.
Called in, 1 hour 10 min wait time.
Oscar is useless until a human arrives
