N.J. Stat. Ann. § 17:23-14

Information furnished pursuant to this act shall be privileged and not a part of any public record. Except as may be required by law other than P.L.1963, c. 73 (C. 47:1A-1 et seq.), an authorized governmental agency or insurer or its authorized agent, which receives any information furnished pursuant to this act, shall not release that information to public inspection. The information shall not be subject to subpena duces tecum in a civil or criminal proceeding unless, after reasonable notice to the insurer or its authorized agent and the authorized governmental agency which has an interest in the information and a hearing, the court determines that the public interest and an ongoing investigation by the authorized governmental agency, insurer or its authorized agent will not be jeopardized by obedience to the subpena.
