N.J. Stat. § 40:74-7
Any ordinance or measure, except an ordinance, or portion thereof, fixing the salaries, wages or compensation of the employees of the municipality, that the board of commissioners or the qualified electors of the municipality shall have authority to enact, the board may on its own motion submit to the electors for adoption or rejection at a general election, regular municipal election, or special municipal election in the same manner and with the same effect as is herein provided for ordinances or measures submitted on petition. At any special election called under the provisions of chapters 70 to 76 of this Title (R.S. 40:70-1 et seq.), there shall be no bar to the submission of other questions to a vote of the electors in addition to the ordinances or measures provided for in this section and R.S. 40:74-5 and R.S. 40:74-9, if the other questions are such as may legally be submitted at such election. If the provisions of two or more measures approved or adopted at the same election conflict, then the measure receiving the highest affirmative vote shall control.
