HRS §435E-46
Testifying cannot be refused due to self-incrimination
You must testify or provide documents when ordered by the commissioner, even if it might incriminate you. But if you claim your right against self-incrimination and are forced to testify, you cannot be prosecuted for what you reveal. You can still be punished for lying or contempt.

The statute, as written — Attendance and testimony
No person is excused from attending or testifying or from producing any document or record before the commissioner, or in obedience to the subpoena of the commissioner or any officer designated by the commissioner, or in any proceeding instituted by the commissioner, on the ground that the testimony or evidence (documentary or otherwise) required of the person may tend to incriminate the person or subject the person to a penalty or forfeiture; but no individual may be prosecuted or subjected to any penalty or forfeiture for or on account of any transaction, matter, or thing concerning which the individual is compelled, after validly claiming the individual's privilege against self-incrimination, to testify or produce evidence (documentary or otherwise), except that the individual testifying is not exempt from prosecution and punishment for perjury or contempt committed in testifying.
