N.J. Stat. § 34:15-60
The director, each deputy director and each of the referees shall have the same power as the Superior Court to issue subpoenas to compel the attendance of witnesses and the production of books and papers. The fees for the attendance of witnesses shall be such as are now provided for the attendance of witnesses in other civil cases, and shall be paid by the party arranging for the attendance of such witnesses. The subpoenas shall be authenticated by the seal of the department, and either party to any such proceeding may, without charge, secure subpoenas from the director, a deputy director or any referee. Misconduct on the part of any person attending a hearing, or the failure of any witness, when duly subpoenaed to attend or give testimony shall be punishable by the director, each deputy director and each of the referees, in the same manner as such failure is punishable by the Superior Court in a case therein pending.
