Kim Dotcom's lawyers were back in court today trying to force the release of government information relating to Mr Dotcom's residency.
Mr Dotcom claims his residency here was part of an agreement between the New Zealand and United States governments which would ultimately aid his extradition.
Speaking to the media outside court, Kim Dotcom's lawyer Paul Davison says they have presented evidence of a meeting four years ago between Mr Key and the Chief Executive of Warner Brothers.
"There was a meeting back in October 2010 attended by the senior people of immigration of New Zealand and the Minister of Immigration," Mr Davison says.
"But that's as far as the evidence goes at this stage."
The elusive Warner Brothers email won't be part of any evidence presented today.
