During a week-long stay, Ms Collins will discuss “a range of justice policy issues” with top echelon legal figures in the United States.
Her meetings include US Attorney General Eric Holder, Jr, who heads the Department of Justice, and the Secretary of the Department of Homeland Security, Janet Napolitano, who visited New Zealand earlier this year.
When asked if Ms Collins would raise the litigation against Dotcom during any of her meetings in America, a spokeswoman for the minister said “certainly not”.
“That would be highly inappropriate,” she said.
Dotcom is fighting extradition to the United States where he faces allegations of internet piracy.
The Megaupload millionaire’s court case was a topic of interest in the United States recently, when Hollywood lobbyists raised the case with Prime Minister John Key during his trip to Los Angeles.
