The Chief Ombudsman publishes data on OIA complaints received against Ministers and agencies on a six-monthly basis. The data is grouped into two spreadsheets - one for complaints received, and one for complaints completed.
This spreadsheet lists the Minister or agency involved, the nature of the complaint, and whether the complaint came from a private individual, the media, a political party or other type of organisation. It also includes details about the outcome of the complaint.
Where the Ombudsman formed a final opinion, you can see whether that upheld the Minister's or agency's decision, and if not, what they did wrong (eg, the request was refused when it shouldn't have been). Finally, you can see information about the remedies achieved as a result of the Ombudsman's intervention.
