The Government Communications Security Bureau did not have a warrant to intercept communications in the lead-up to the raid on the Dotcom mansion in January.

Prime Minister John Key has revealed the GCSB was acting without his sign-off when it was working with police to locate people who were subject to arrest warrants.

He said he had not issued a warrant and was not briefed on the operation.
