Haw. Code R. § 12-41-91
Two members of the arbitration panel shall be selected by the parties; one shall be selected by the employer and one shall be selected by the exclusive representative. The neutral third member of the arbitration panel, who shall chair the arbitration panel, shall be selected by mutual agreement of the parties. In the event that the parties fail to select the neutral third member of the arbitration panel within thirty days from the date of notice of the labor dispute, or such additional time as agreed to by all parties, the board shall request the American Arbitration Association, or its successor in function, to furnish a list of five qualified arbitrators from which the neutral arbitrator shall be selected. Within five days after receipt of such list, the parties shall alternatively strike names from the list until a single name is left, and that arbitrator named shall be immediately appointed by the board as the neutral arbitrator and chair of the arbitration panel, and the board shall serve a copy of its certification of appointment of such panel upon all parties.
