According to Air New Zealand Ticket Refund Policy, Cancellation would not be applied if the flight booked wit within 7 days of scheduled departure. If an Air ticket is reserved by any outsider travel service, via the web or offline medium, travelers would be charged a cancellation expense and the ticket will not come under the cancellation policy and refund will not be applicable anymore. If passengers want to gain full refund against cancellation, then passengers should cancel their booked ticket within risk free time. Visit our website to know more.
