New Jersey is North and South, and a good number of people claim there to be a Central section, as well. For me personally, it's North and South.
The state itself, for tourism I guess, classifies us into 6 regions: Gateway, Greater Atlantic City, Skylands, Shore, Southern Shore, and Delaware River.

) but it mentions the other 5 at the bottom of the whole intro part.)
