Public Sector Management Act 1994

An action or proceeding does not lie against a person for or in relation to any oral or written report made in good faith by that person on or in relation to—

work performed, or proposed to be performed, by an officer or employee; or

conduct of an officer or employee.

A report is taken to have been made in good faith if the person by whom the report was made was not actuated by ill will to the officer or employee affected or by any other improper motive.

Subsection (1) does not apply in relation to a report unless—

the person who made the report believed on reasonable grounds that it was the function or duty of the person to whom the report was made to receive the report; and

for a report containing matter that was false or misleading in a material respect—the person who made the report did not know, and could not with reasonable diligence have ascertained, that the report contained matter that was so false or misleading.
