Labour MP Phil Goff will not face any sanctions for leaking the details of a report by the spy watchdog a day before it was publicly released.
Inspector-General of Intelligence and Security Cheryl Gwyn said this morning she had accepted Mr Goff's "full and unreserved" apology.
"The Inspector-General will not take the matter any further," she said in a statement.
Mr Goff breached a confidentiality order last month by disclosing details about her report on the Security Intelligence Service's release of information to blogger Cameron Slater.
Ms Gwyn said no classified information was disclosed, but Mr Goff's leak led to premature media reporting on the content of the report, "to the detriment of other witnesses to the inquiry, particularly those adversely affected by the report".
