N.J. Stat. Ann. § 40A:14-179

1. Notwithstanding any other law to the contrary whenever there is a police department organized in any political subdivision of this State and a chief of police appointed to be the executive head of such department, the starting base salary of said chief of police and the deputy chief shall be set at a rate that is higher than the highest base salary of the ranking police officer next in command below the chief of police or deputy chief of police as appropriate. Thereafter, whenever new base salary ranges are set by the governing body or appointive authority, unless the chief of police or deputy chief shall consent to a lesser adjustment, the base salary for the chief of police and his deputy chief shall be adjusted to ensure that their base salaries remain higher than the base salaries of other ranking supervisory officers in the department.
