The New Zealand Esperanto Association organises a conference annually. Sometimes this is done in conjunction with the Australian Esperanto Association and takes place in Australia (in Indonesia it was held in 2018). Usually there is a summer school where you can take part in an intensive Esperanto course with experienced Esperanto teachers. Of course, this a perfect opportunity to practice your new Esperanto skills and see the language in action since there are often visitors from overseas whose first language is not English.
There are many other events around the world. For more details on what is in this part of the world as well as further afield take a look at the Events page.
