The police investigation into the Government Communications Security Bureau's surveillance of internet millionaire Kim Dotcom has been held up by legal proceedings in the High Court.
Green Party co-leader Russel Norman laid a complaint with the police alleging the GCSB had breached the Crimes Act by unlawfully monitoring Mr Dotcom.
In a letter to Dr Norman, the police say the investigation is being held up because the bureau has now become a party to Mr Dotcom's legal proceedings in the High Court.
The police say they expect to give Dr Norman an update on their inquiries early next year.
Last month, the High Court ruled the security bureau could be called as a defendant in the case against Mr Dotcom which means he will get access to information the Bureau collected on him.
