N.J. Stat. § 17:33A-11
Papers, documents, reports, or evidence relative to the subject of an investigation under this act shall not be subject to public inspection except as specifically provided in this act. The commissioner shall not detain subpenaed records after an investigation is closed or, if a claim for a civil penalty is filed by the commissioner pursuant to section 5 or subsection d. of section 7, upon final disposition of the claim by a court of competent jurisdiction, whichever shall be the later date. Subpenaed records shall be returned to the persons from whom they were obtained. The commissioner may, in his discretion, make relevant papers, documents, reports, or evidence available to the Attorney General, an appropriate licensing authority, law enforcement agencies, an insurance company or insurance claimant injured by a violation of this act, consistent with the purposes of this act and under such conditions as he deems appropriate. Such papers, documents, reports, or evidence shall not be subject to subpena, unless the commissioner consents, or until, after notice to the commissioner and a hearing, a court of competent jurisdiction determines that the commissioner would not be unnecessarily hindered by such subpena. Division investigators and insurance company fraud investigators shall not be subject to subpena in civil actions by any court of this State to testify concerning any matter of which they have knowledge pursuant to a pending insurance fraud investigation by the division, or a pending claim for civil penalties initiated by the commissioner.
