And the Herald has learned the action could expand beyond assets seized before the 2012 raid. Investment in Dotcom's new venture Mega has created a new fortune - although no shares are held in his name.
The Hollywood studios' application for the freezing order comes after the High Court told Dotcom he could have access to money seized at the time of the raid.
A ruling refused requests from authorities to renew an order restraining the funds.
The case is under appeal but Dotcom is lined up to have an estimated $12 million returned.
The Hollywood studios' New Zealand lawyer Matt Sumpter, confirmed the ruling releasing the funds was a factor in the case.
