Recording companies have followed the movie studios' lead and are also seeking freezing orders over Kim Dotcom's assets, the High Court at Auckland heard this morning.
Major movie studios and records labels are both suing Dotcom and his associates.
20th Century Fox, Disney, Paramount, Universal, Columbia Pictures and Warner Bros claim Dotcom-founded Megaupload and its key operators "facilitated, encouraged, and profited from massive copyright infringement of movies and television shows" before it was shut down in 2012.
They have filed a lawsuit against Dotcom, Megaupload, majority shareholder Vester Ltd, chief technical officer Mathias Ortmann, and programmer Bram van der Kolk.
The studios claim the defendants generated more than US$175 million in illicit profits and cost US copyright owners more than half a billion dollars.
