Kim Dotcom's use of social media to discuss his long-running legal battle is interfering with court processes, a Crown lawyer says.

Dotcom's legal team returned to court today in a bid to access government documents to help the internet mogul's case.

This latest request for documents came a week after the Supreme Court refused Dotcom's request to access evidence the US Government has against him in his extradition case.

Crown lawyers raised Dotcom's prolific use of Twitter as an issue during today's legal proceedings in the High Court in Auckland.

This included concerns over Dotcom posting details of a confidential email between lawyers to more than 350,000 Twitter followers.

Crown lawyer Kristy McDonald, QC, said Dotcom's use of Twitter has "demonstrated considerable disregard" for court processes.

"Is this about obtaining documents so they can be put out in the public arena?"

Dotcom's lawyer Paul Davis, QC, said the idea his client sought documents merely to make them public could not be further from the truth.

There were still documents and emails to come to light which would help Dotcom's defence case, he said.

However, Crown lawyers argued all relevant documents have already been released to Dotcom's legal team.

An interim suppression order banned the publication of any details revealing the authors or content of the documents sought by Dotcom's lawyers.

The case will continue in the High Court tomorrow.

The US is seeking to extradite Dotcom to face charges of copyright conspiracy, racketeering and money-laundering allegedly carried out by his file-sharing company, Megaupload.

An extradition hearing is expected to be held this year.

Meanwhile, the lawyer for Dotcom's former bodyguard appeared in a separate case in the High Court in Auckland today.

Dotcom is attempting to stop Wayne Tempero from revealing details about the personal and business life of his former boss.

The bodyguard quit Dotcom's employment last year.

Tempero's lawyer indicated he might attempt to revoke the temporary gag order made against Tempero.
