N.J. Stat. § 34:6B-15
Unless otherwise permitted or required by law, an employer shall not knowingly or purposefully publish, or cause to be published, any advertisement that solicits applicants for employment where that advertisement explicitly provides that the employer will not consider any applicant who has been arrested or convicted of one or more crimes or offenses. The provisions of this section shall not apply to any advertisement that solicits applicants for a position in law enforcement, corrections, the judiciary, homeland security, or emergency management, or any other employment position where a criminal history record background check is required by law, rule or regulation, or where an arrest or conviction by the person for one or more crimes or offenses would or may preclude the person from holding such employment as required by any law, rule or regulation, or where any law, rule, or regulation restricts an employer's ability to engage in specified business activities based on the criminal records of its employees. Nothing set forth in this section shall be construed as prohibiting an employer from publishing, or causing to be published, an advertisement that contains any provision setting forth any other qualifications for employment, as permitted by law, including, but not limited to, the holding of a current and valid professional or occupational license, certificate, registration, permit or other credential, or a minimum level of education, training or professional, occupational, or field experience.
