Labour MP Phil Goff has accused Prime Minister John Key of having a direct hand in the release of intelligence documents to blogger Cameron Slater for the purposes of embarrassing the former Labour leader.
Inspector-General of Intelligence and Security Cheryl Gwen began hearings today as part of her inquiry into the release of information from the New Zealand Security Intelligence Service (SIS) to Mr Slater in 2011.
The inquiry stemmed from allegations made in Nicky Hager's book Dirty Politics, in which the author claimed the decision to release an Official Information Act document was politically motivated and Mr Slater was tipped off in advance about the exact contents and timing of the release.
The document showed Mr Goff had been briefed on Israeli backpackers the SIS had initially suspected were spies - a meeting he did not recall at the time.
Speaking to the inquiry under oath, Mr Goff said his suspicion at the time was that material was disclosed to Mr Slater to help him make an OIA request.
