I had to pay a departure tax last time I was in NZ, but flew out of Christchurch. almost 8 years ago
This is on the www.tourism.org.nz website:
A tax of NZ$25 must be paid at the airport when you leave New Zealand, unless you are leaving from Auckland airport. Please note that this tax is only included in your ticket price if you are departing from Auckland International Airport. Children under 12 years of age are exempt from the departure tax fee.
