Labour's demanding disclosure of the Attorney-General's roles in the Hobbit deal and Kim Dotcom's citizenship.

The Dotcom email released yesterday references Attorney General Chris Finlayson implying he would do everything in his power to help the movie studio.

David Cunliffe says they've had trouble under the Official Information Act getting details on Mr Finlayson's involvement.

"And the Attorney-General's correspondence and communications with Warner Bros should be made public - all of them."
