The Ombudsman is an officer of the New Zealand Parliament who independently looks into complaints. The core jurisdiction of the office covers cases of maladministration. Over the years, it has been progressively expanded to include complaints under the Official Information Act 1982 and Local Government Official Information and Meetings Act 1987, as well as whistleblower complaints under the Protected Disclosures Act 2000. Additionally, the Ombudsman serves as one of New Zealand's national preventive mechanisms under the Optional Protocol to the Convention against Torture.
