The Government Communications Security Bureau has confirmed knowledge of the surveillance of Kim Dotcom went to the very top of the organisation.
In September this year, the spy agency admitted that it illegally monitored the internet entrepreneur after relying on incorrect police information about his residency.
In response to an Official Information Act request from Radio New Zealand, the GCSB said acting director Hugh Wolfensohn was informed about the surveillance which was conducted in December and January.
Current director Ian Fletcher will not say how many other people knew, to protect future operations.
During the surveillance, Mr Fletcher says the GCSB communicated only with police, specifically its Organised and Financial Crime Agency.
