The Civil Aviation Act 2023 is New Zealand's principal civil aviation law. It sets the legal framework for aviation participants, the Civil Aviation Authority, the Director of Civil Aviation, aircraft registration, aviation documents, medical certification, accident and incident notification, aviation security, airports, and parts of international aviation law.
For most businesses, the practical point is straightforward. If you operate aircraft or drones, provide aviation services, work in security-controlled airport areas, or rely on aviation approvals, this Act is likely part of your compliance base. You will usually need to read it together with the civil aviation rules that apply to your operation.
