N.J. Stat. Ann. § 40:69A-2

A charter commission of five members shall be elected by the qualified voters at the same time as the public question is submitted. Duly nominated candidates for the office of charter commissioner shall be placed upon the ballot containing the public question in the same manner as is provided by law for candidates nominated by petition for other offices elective by the people of a single municipality, except that they shall be listed without any designation or slogan. Each voter shall be instructed to vote on the question and, regardless of the manner of his vote on the question, to vote for five members of a charter commission who shall serve if the question is determined in the affirmative.
