Hawaii Revised Statutes Division 5. Crimes and Criminal Proceedings § 806-22

When there are several charges against any person for the same act or transaction, or for two or more acts or transactions connected together, or for two or more acts or transactions of the same class of crimes or offenses, which may be properly joined, instead of having several indictments, informations, or complaints, the whole may be joined in separate counts in one indictment, information, or complaint. If two or more indictments, informations, or complaints are found or entered in such cases, the court or district judge may order them to be consolidated.
