Internet tycoon Kim Dotcom will be back in court today, seeking access to evidence the crown plans to use against him in an extradition hearing.
A High Court judge has already indicated the Crown may have to hand over the evidence but Crown lawyers have said it would take more than two months to collect.
Dotcom's legal team is also seeking the return of assets and data seized in the police raid on his mansion in January.
On Thursday, the high court ruled that the raid was illegal, because police had used the wrong search warrants.
Dotcom and three other men were arrested at Dotcom's $30 million rented mansion in Coatesville, Auckland, in a police raid on January 20.
They face charges in the US of racketeering, copyright infringement and money laundering and are awaiting proceedings to extradite them to the US.
Dotcom has denied any wrongdoing.
The US Government is seeking to extradite Dotcom on the charges.
He is currently on bail and will face the extradition hearing in August.
