From the Office of the Privacy Commissioner of New Zealand:
The Privacy Commissioner has issued updated codes of practice to take into account a number of technical changes made by the Harmful Digital Communications Act (HDCA).
The amendments align the codes of practice with statutory amendments made to related legislation and come after a public submission process.
The recently passed HDCA amended the general principles of the Privacy Act by placing a limitation on the use and disclosure of personal information obtained from publicly available publications (see our media release on the HDCA for more information).
In order to align the codes of practice with the Privacy Act, the amendments reflect equivalent provisions about the use and disclosure of personal information in the Health Information Privacy Code, Telecommunications Information Privacy Code and the Credit Reporting Privacy Code.
