The link you sent:
http://www.njleg.state.nj.us/bills/BillView.asp
was for a bill, not a law.
Since this bill became law in 2003, amending a previous law, you may want to consult Nexis Uni if your project concerns current New Jersey law as there may have been changes since it was passed.
As far as citing the bill or law, I'd suggest consulting this website on Basic Legal Citation:
https://www.law.cornell.edu/citation/
You'll find examples for citing bills and laws under Examples of Citations in the left-hand menu.
