When you are a contact tracer, you must keep some information secret. You cannot tell someone you contact that another person may have given them an infectious disease. You also cannot tell them that another person may have put them at risk of getting the disease. You get this information under a part of the law, or under section 92ZZF. You must not disclose the identity of the person who may have transmitted the disease or exposed them to risk.

If you get information as a contact tracer, you can only use it to manage infectious diseases. This is despite what the Privacy Act 2020 says. However, this does not stop someone from accessing or sharing their own information under that Act or any other law. You can use the information to help manage diseases, but you must follow the rules.
