The Director of the Civil Aviation Authority of New Zealand has special powers related to aviation documents. When you need to get a new aviation document or renew an old one, the Director can do several things. They can create and run exams and tests for you. They can also do flight testing. This means they might watch and assess how you fly. The Director can do anything else needed to make sure these exams, tests, and flight assessments work properly. They do all of this to help decide if you should get or keep your aviation document.
