We are unable to provide information for this part of your request as this information is not reported
to Te Whatu Ora. This information would be included in individual case files held by hospitals. In
order to provide you with this information, Te Whatu Ora staf would have to manually review over
a thousand files. As such, this part of your request is refused under section 18(f) of the Act. The
greater public interest is in the effective and efficient administration of the public service.
We have considered whether Te Whatu Ora would be able to respond to your request given extra
time, or the ability to charge for the information requested. I have concluded that, in either case, Te
Whatu Ora’s, ability to undertake its work would stil be prejudiced.
