Assistant Commissioner Malcolm Burgess was an integral figure leading up to the raid on Dotcom's mansion.
Police are refusing to say whether one of the country's most senior officers knew about illegal spying on Kim Dotcom, even though he was an integral figure in the months leading up to the high-profile raid.
Assistant Commissioner Malcolm Burgess first heard the FBI's formal request for help and acted as the conduit to police hierarchy.
He was also director of the Organised and Financial Crime Agency of New Zealand, which ran the operation leading to Mr Dotcom's arrest, and later approved the use of the elite Special Tactics Group to raid Mr Dotcom's mansion in the January 20 raid.
The police are facing criticism after asking the Government Communications Security Bureau to spy on the internet tycoon.
