Kumar says he has invited Dotcom to speak at InternetNZ's Net Hui conference next month to speak about the commercial aspects of creating a cloud business, but Dotcom has declined.

"I guess he's missed an opportunity to speak on that," he says.

US authorities claim Dotcom and co-accused Mathias Ortmann, Fin Batato and Bram van der Kolk used the Megaupload website to knowingly make money from pirated movies and games. They have charged him in the US with multiple copyright infringement offences. An extradition hearing has been set down for August 6.

Justice Winkelmann has ordered that an independent barrister be appointed to review "all items seized for the purpose of identifying irrelevant and privileged material".

She also ordered that the "clones containing only relevant and non-privileged material located on the seized electronic items (the disclosable clones) be created and provided to the United States authorities."
