Hawaii Revised Statutes Division 2. Business § 484-19

(a) In addition to the methods of service provided for in the Hawaii rules of civil procedure, service may be made by delivering a copy of the process to the office of the director of commerce and consumer affairs, but it is not effective unless the plaintiff (which may be the director in a proceeding instituted by it):

(b) If any person, including any nonresident of this State, engages in conduct prohibited by this chapter or any rule or order hereunder, and has not filed a consent to service of process and personal jurisdiction over the person cannot otherwise be obtained in this State, that conduct authorizes the director to receive service of process in any noncriminal proceeding against the person or the person's successor which grows out of that conduct and which is brought under this chapter or any rule or order hereunder, with the same force and validity as if served on the person personally. Notice shall be given as provided in subsection (a).
