Check in process
When you are checking in at the airport, ensure that you have your NZeta handy as well as your flight itinerary. Your date of departure out of NZ will be checked to confirm that you have a round trip ticket.
Flying
Most international flights will end up flying to Auckland or Christchurch, and from those cities, there are multiple flights per day to Queenstown.
Tip: depending on where you are coming from, check flights via Australia, as many cities in Australia will fly jets directly into Queenstown Airport.
Ensure your camera is ready when coming into Qtn, the views are worth it :-)
Visa
An NZeta visa (tourist visa) is required to enter NZ. Upon submission, this visa can take up to 72 hours to process, so please do not wait until the last minute to apply. You will not be allowed to check in at the airport without an approved visa.
I highly recommend downloading the app to apply - it makes the process quick and easy. For more information see https://nzeta.immigration.govt.nz/
