Privacy Act 2020

Principle 1 states that organisations must only collect personal information if it is for a lawful purpose connected with their functions or activities, and the information is necessary for that purpose. This principle is about data minimisation.

When asking people for their personal information, think carefully about why you are collecting it. Don’t collect people’s identifiers such as name, phone number, etc unless it’s necessary for your collection purpose. If the personal information you are asking for isn’t necessary to achieve something closely linked to your organisation’s activities, you shouldn’t collect it.
