You are protected from unfair treatment at work, but there is an exception. This exception is for work that involves keeping New Zealand safe. The law does not apply to restrictions on who can do this kind of work. You can be restricted from doing work involving national security because of your beliefs or opinions. This includes your religious or ethical beliefs, or your political opinions. It also includes things like your disability or family status, as defined in section 21(1)(h)(iii) or section 21(1)(h)(iv), and section 21(1)(l)(iii) or section 21(1)(l)(iv). Your national origin, or the national origin of your relatives, can also be a reason. It is not against the law to not give a job to someone under 20 who needs a secret or top secret security clearance to do work involving national security, as stated in section 22.
