Later in 1946, Lester Patrick scouted Kwong and was impressed, signing him for the New York Rovers, a farm team of the New York Rangers. Kwong scored a goal in his debut for the Rovers against the Boston Olympics in Boston on October 27, 1946. At Madison Square Garden on November 17, 1946, Shavey Lee presented Kwong with the Keys to New York's Chinatown. Kwong went on to lead the New York Rovers in scoring in 1947–1948 with 86 points in 65 games.
