One of the lawyers for Megaupload founder Kim Dotcom says New Zealand needs to stand up to US agencies.
Dotcom's lawyers are seeking a judicial review of the legality of the search warrants used by police who raided his mansion on behalf of the FBI.
The US Government is seeking to extradite Dotcom and three New Zealand-based associates on charges including copyright infringement and wire fraud relating to the file-sharing website Megaupload.
Prosecutors allege a "mega conspiracy''.
Dotcom denies the charges and says his website was legitimate.
