The head of the FBI has been in New Zealand this week for top-level meetings.
James Comey flew into Wellington to discuss a number of issues of "safety and security of the citizens of both countries", the FBI says.
He met separately with Police Minister Judith Collins, Police Commissioner Mike Bush and US Ambassador Mark Gilbert.
In a statement, the FBI says the US-New Zealand law enforcement partnership "remains steadfast".
"We welcome the opportunity to work together to share critical information that will safeguard our Americans and New Zealanders from global threats."
The trip was "routine business" and discussions included drugs and cyber-crime.
Newshub understands Mr Comey has since left New Zealand.
