The turnout at a lunchtime meeting with Privacy Commissioner John Edwards showed the matter of private information is a big issue.
Law firms, churches, health, welfare, child care, education and training groups were represented in Whangarei last week.
The Privacy Act was often represented in the community as "you can't tell anyone anything," Mr Edwards said. But issues around personal information were "quite tricky" and it was important the public knew about the obligations on agencies holding that information, he said.
Privacy Commission staff also ran a workshop for the Whangarei District Council.
The council was earlier this year ordered by the Human Rights Review Tribunal to train councillors and management staff about their obligations under the Privacy Act 1993. That followed the tribunal awarding Maungakaramea resident Wayne Deeming $2000 for humiliation, loss of dignity and injury to feelings after a breach.
