OIA performance stats: The public data

As part of my project on the performance of government agencies under the Official Information Act, I've been gathering public information. Some agencies publish data on their OIA performance in their annual reports. And the Annual report of the Ombudsmen [PDF] gives some information on complaints. Here's the information for 2008-2009 so far:

Agency	Requests	On time	Complaints
Land Information New Zealand	Less than 71	100%	Unknown
Ministry of Pacific Island Affairs	2	100%	Unknown
Ministry of Justice	183	98%	Unknown
Ministry of Defence	64	97%	Unknown
Department of Internal Affairs	17	94%	Unknown
The Treasury	267	85%	Unknown
Te Puni Kōkiri	Unknown	80.5%	Unknown
Ministry for the Environment	175	71%	Unknown
Ministry of Health	643	Unknown	24
Ministry of Foreign Affairs and Trade	192	Unknown	Unknown
Department of Conservation	162	Unknown	Unknown
Ministry of Women's Affairs	8	Unknown	Unknown

(Source: All information is from agency annual reports. Treasury's data has been calculated from its sub-departmental breakdown. I've excluded agencies with complaints but no data on requests or response rates because it seems rather pointless)

Its disturbing how little information there is. There are 34 agencies listed in the schedule to the State sector Act and classed as "public service departments" - but only 12 give any data. Pretty obviously some of these agencies - LINZ, Pacific Island Affairs and Justice - are doing well. Others, particularly MfE and TPK, are doing very badly. A mere 80% compliance with the law is unacceptable.
