Whaleoil blogger Cameron Slater is going to the High Court in an effort to stop media publishing information taken by the hacker known as Rawshark.
The blogger has filed papers with the court seeking to ban media and the hacker from any further publication of his emails and social media conversations.
In a case to be heard tomorrow in the High Court at Auckland, Slater will ask for a legal halt to use of the information by the New Zealand Herald, TV3 and Fairfax Media. He also wants the news organisations to turn over to him the information they have.
Slater's Statement of Claim for the case says his Gmail and Facebook accounts were "illegally accessed". The court papers stated the accounts had "tens of thousands of emails spanning a period of more than ten years".
The papers stated Slater's Gmail accounts included exchanges with accountants, doctors, lawyers, psychiatrists along with personal communication with his wife, and "a large amount of information he received in his capacity as a journalist".
The move to injunct comes two weeks after the publication of Nicky Hager's Dirty Politics book, which accused the National Party of attacking opponents through Slater's Whaleoil blog.
Since the book was published, the hacker has released material online and through three news organisations named in Slater's application for an injunction.
The hearing is set for 2.15pm at the High Court in Auckland.
