A late-night incident which involved a woman being dragged into the back of a car in Wellsford, north of Auckland, was a domestic incident.
A member of the public alerted police to the Tuesday night altercation after seeing a woman being pulled into a car by a man.
Detective Senior Sergeant Brett Batty said both individuals involved had been spoken to.
"It appears to have been a domestic-related argument and staff will be dealing with it along those lines.''
It was not yet known whether charges would be laid, Mr Batty said.
