Prime Minister John Key may have discussed internet millionaire Kim Dotcom during an informal chat with United States President Barack Obama.
Mr Key spoke with Mr Obama before a meeting at the East Asia Summit in Cambodia.
Kim Dotcom is facing extradition to the US from New Zealand on charges of internet piracy and money laundering, relating to his file-sharing website Megaupload.
Mr Key told reporters his conversation with the president was wide-ranging, and wouldn't deny they talked about Mr Dotcom.
"I had quite a long chat with him about a range of issues. I am not going to go through what those issues might be."
He said he had private conversations with people all the time.
Mr Key did confirm he discussed the issue of Gaza with Mr Obama.
