Begin researching programs to teach abroad in New Zealand one year before the expected date of departure. Websites such as Go Abroad and New Zealand Education are good places to start.
Pick a program that best suits your desired criteria for teaching abroad. Many programs in New Zealand are geared towards those who would like to teach English as a second language and can last for six months to a year.
Complete either a college degree or TEFL (Teaching English as a Foreign Language) certification, whichever is required by the program you choose.
Fill out and turn in the teaching abroad application as soon as you choose a program.
Apply for a passport if you need one and work visa after acceptance into a teaching abroad program and no less than six months before departure.
Buy an airplane ticket three months before you leave. Check with the teaching abroad program to find out if the program covers the airline ticket or if it is an out-of-pocket expense.
