 The four Public Register Privacy Principles (PRPPs) cover any "register, roll, list or other document" held by governmental or quasi-governmental agencies under Schedule 2 of the Privacy Act, to which the public has statutory rights of access.The PRPPs restrict the use of information compulsorily supplied from the public register.In exceptional circumstances, when the Privacy Commissioner is satisfied the public interest outweighs privacy protection, agencies can be authorised to use personal information in a manner that would usually breach the IPPs or other provisions under the Act.
