Details remain murky after the Deputy Director of the FBI Mark F Giuliano met with Attorney General Chris Finlayson at the Beehive today.
Mr Finlayson is refusing to say whether they discussed the issue of Kim Dotcom's extradition, insisting that he doesn't discuss publicly, issues before the courts.
"I'm not talking to you about the Kim Dotcom case....I discussed with him issues of cyber crime which is what I discussed with a quintet of attorneys general in London recently," says Mr Finlayson.
He insists Mr Giuliano was merely popping in for a courtesy call on his way home from Australia.
The US government is trying to extradite Kim Dotcom over alleged copyright breaches. As Attorney General Mr Finlayson is in charge of Crown Law, the agency dealing with the US government over the extradition.
"I couldn't guess what is happening in the meeting but i'm sure the US is frustrated with their efforts around Dotcom," Green Party co-leader Russell Norman.
Mr Dotcom is fighting the extradition in the New Zealand courts.
Meanwhile, a ONE News/Colmar Brunton poll has found New Zealanders are more trusting of Mr Dotcom than the Prime Minister.
On the question of just when Mr Key knew about Mr Dotcom, almost half of respondents believed Mr Dotcom.
Just a third of voters believe Mr Key.
