Attorney-General Chris Finlayson has confirmed he met the deputy director of the United States' FBI Mark Giuliano this morning.
He said the two had discussed issues of cyber-crime.
Asked if he had talked about Kim Dotcom, who the FBI wants to extradite to the United States to face copyright charges, Finlayson said: "I am not talking about specific cases with anyone and certainly not that issue because it's before the courts."
They had talked about the general issue of cyber crime, he said.
The director-general had meetings in Australia "and was on his way home to the US and called in to say good morning to me."
Justice Minister Judith Collins said she did not meet him.
Green co-leader Russel Norman said it was "pretty likely" Dotcom was discussed at the meeting, but it was impossible for him to know.
It was a highly sensitive issue for the New Zealand and United States Government.
It was clear throughout that the Dotcom issue was a coordinated activity between the US and NZ governments so it was hardly surprising.
"I'm sure the US is frustrated with their efforts around Dotcom."
