City on the Passaic (6)

I believe the answer is:

newark

(Other definitions for newark that I've seen before include "Notts. market town" , "east coast port" , "Notts. town; NJ city" , "24 Down in Nottinghamshire" , "Town on river Trent where King John died" .)

I've seen this clue in the King Feature Syndicate.
