Guy Sayers, of the Official Assignee, confirmed a new restraining order had been granted over the property on February 1.
However, he said there was no suggestion that the Dotcom family have to leave.
"Certainly no one is going to be evicted. It's no different to any other restraining order where I take custody and control of property, but the family can still live there.
"We'll set up a property inspections to make sure there's no damage, but other than that, the family can still enjoy it."
The OA has also returned to the "Dotcom Mansion" this morning to seize property, including a luxury car and artwork.
The car was originally seized in the January 20 raids but had to be returned because of a paperwork error.
Dotcom, the founder of the Megaupload website, is in custody awaiting an extradition hearing after being accused by the FBI of being at the centre of a global piracy and money-laundering conspiracy.
He has denied any wrongdoing.
