Chief Ombudsman Peter Boshier says the Treasury is "an exemplar" for other agencies in its policy of releasing all substantive Official Information Act responses on its website.

Mr Boshier has completed an investigation into the way the Treasury works with OIA requests.

He says he has found a positive culture at the Treasury around the importance of the OIA and openness and transparency, consistent with the Treasury’s role as a provider of free and frank advice.

He says he has made no formal recommendations, as he did not identify any conduct by the Treasury that was wrong, unreasonable, or contrary to law.

His report includes suggested actions for improvements to Treasury practice; mostly in the areas of training and guidance, gathering better information on the time involved in processing and responding to OIA enquiries, and clarifying some of the information on its OIA webpage.
