The "best flights" web site (too lazy to find a link) has a link to a "tax engine" that will show taxes by country and airline. The taxes are vast and huge (but refreshingly small in some isolated locations - like international departures from NZ).</font>
But not included in the ticket charges at NZ, you pay your departure tax at the airport before going airside. Something like NZ$25 from memory.
