Prime Minister John Key does not believe there is a need for an inquiry into the way New Zealand police handled the raids on the house of Megaupload founder Kim Dotcom.
The Chief Judge of the High Court ruled last week that search warrants used in the raid in January were invalid.
The Green Party says an agency such as the Independent Police Conduct Authority needs to investigate the actions of the police.
Mr Key told TVNZ he does not see any particular need for an inquiry. He said the Greens ask for an inquiry into everything.
Megaupload was indicted in a federal court in Virginia, USA, on 19 January this year and the site was shut down. Mr Dotcom and three co-accused were arrested in Auckland, New Zealand, the following day.
Formal papers requesting their extradition were lodged by the United States in early March.
