N.J. Stat. § 40A:9-145.5
Any tax collector certificate may be revoked or suspended by the director for dishonest practices, or willful or intentional failure, neglect or refusal to comply with the Constitution of the State of New Jersey or laws relating to the collection of taxes, or inefficiency, or inability to properly fulfill the duties and functions of tax collector in compliance with laws and regulations pertaining thereto or other good cause. The governing body or chief executive officer of any municipality may request a review by the director of the behavior or practices of a certified tax collector. No certificate shall be revoked or suspended except upon a proper hearing before the director or his designee after due notice. If the tax collector certificate of a person serving as tax collector shall be revoked, such person shall be removed from office by the director, his office shall be declared vacant, and such person shall not be eligible to hold that office, nor may he make application for recertification, for a period of five years from the date of such revocation.
