New Zealand has a number of options for your CELTA course. Many of the CELTA centres are based in the Auckland, and there’s also some that support Canterbury, Wellington and elsewhere. Given New Zealand’s relatively small size, you should have no trouble finding a CELTA school without having to fly to neighbouring countries.
If you’re looking to travel to New Zealand for your CELTA course, you’re in for a treat. It’s a spectacular country and you should definitely schedule some extra time before or after your course to see the sights and explore the culture.
Remember that the list of CELTA centres changes each year. Check the official list on the Cambridge website for the most recent changes.
