Dear Mighty River Power Limited,

On 26 April 2012 you responded to an OIA request from Joshua Grainger seeking
information on the effects of the Mixed Ownership Model with a release of some information and a refusal of the rest for various reasons (http://fyi.org.nz/requests/107-effects-o...). Your response departed from good OIA practice in failing to list the specific documents covered and provide the specific withholding grounds applying to each one, in apparently failing to consider whether the material could be released with redactions to protect the identified harms, and in failing to give the specific reasons justifying redactions in the released material. I would therefore like to request the following information under the Official Information Act 1982:

* A list of all the documents found to have fallen within the scope of Mr Grainger's request; and
* For each document, the specific withholding grounds which are believed to apply, and why they apply to the entire document rather than merely portions of it.
* For the released documents, the specific withholding ground justifying each redaction

I ask that this request be treated urgently. You have the documents, you've clearly made a decision, I'm asking you to document it properly so that it can be challenged if necessary.

Yours faithfully,

Alex Harris
