Hawaii Revised Statutes Division 5. Crimes and Criminal Proceedings § 835-4

(a) When the prospective witness appears before the court, the court must inform the prospective witness of the nature and purpose of the proceeding, and that the prospective witness is entitled to a prompt hearing upon the issue of whether the prospective witness should be adjudged a material witness. The prospective witness possesses all the rights, and is entitled to all the court instructions, with respect to right to counsel, opportunity to obtain counsel and assignment of counsel in case of financial inability to retain such, which, pursuant to rule 5(d)(1), Hawaii rules of criminal procedure, accrue to a defendant arraigned upon a felony complaint in the district court.

(b) If the proceeding is adjourned at the prospective witness' instance, for the purpose of obtaining counsel or otherwise, the court must order the prospective witness to appear upon the adjourned date. The court may further fix bail to secure the prospective witness' appearance upon such date or until the proceeding is completed and, upon default thereof, may commit the prospective witness to the custody of the chief of police for such period.
