N.J. Stat. § 19:14-27
Except as provided by section 19:14-33 of this Title, when any question or proposition shall be submitted to the people of the State at any general election or at any election held to vote on a constitutional amendment, there shall be mailed to each registered voter in the same envelope with the sample ballot a printed copy of the act of the Legislature or constitutional amendment which is so submitted; provided, however, in counties where sample ballots are so folded that they can be mailed to the registrants without being inserted in envelopes, as permitted by section 19:49-4 of this Title, the commissioner of registration shall make such arrangements for mailing the printed copy of the act of the Legislature or constitutional amendment as are practical to enable each registrant to receive a copy thereof.
