Many kiwis travel to learn, so on this page are links to where you can find out about Earthship workshops, builds and seminars happening in other parts of the world. Being an intern or volunteer on a start to finish build is a good way to get a real understanding of how earthships hang together.
In Australia regular workshops are run by Earthship Ironbank- South Australia: http://www.earthshipironbank.com.au/workshops.html
www.earthship.com has a section on internship opportunities run by Earthship Biotecture plus a section for connecting project hosts to people interested in learning and working on Earthship inspired buildings all around the world. See http://earthship.com/Grand-Central/
Another way of training and getting an understanding of how to build an Earthship is to attend the academy in New Mexico, at the Earthship Headquarters. See earthship.com/academy
