An inquiry into the release of a sensitive security document to Whale Oil blogger Cameron Slater within days of requesting it will include access to computer systems, documents and phone records.
In an unusual step, Inspector-General of Intelligence and Security Cheryl Gwyn provided an update about her inquiry this afternoon, in recognition of public interest.
She is looking into whether anything inappropriate took place when the Security Intelligence Service provided Slater with response to an Official Information Act request just days after it was requested, and which was not given to media outlets that had asked also made OIA requests at the time.
"The scale of the inquiry is significant - it involves access to a variety of IT systems, documents, phone records and so forth," Ms Gwyn said.
"I then need to analyse that information, discard what is irrelevant, and then take into account the evidence from those summoned."
