HRS §621C-3
Your testimony cannot be used against you
If a court orders you to testify or produce evidence, that testimony or evidence cannot be used against you in a criminal case. The only exceptions are if you lie, commit perjury, or fail to follow the court's order. You can still be prosecuted for other crimes, but your compelled testimony cannot be used in that prosecution.

The statute, as written — Use immunity
The testimony or production that is compelled under the order, and any information directly or indirectly derived from the testimony or production, may not be used against the person in any manner in a criminal case, except in a prosecution for perjury, for giving a false statement, or for an offense involving a failure to comply with the order; provided that such person may be prosecuted or punished for any crime so long as testimony or production that is compelled under the order, and any information directly or indirectly derived from such testimony or production, is not used against such person in such prosecution.
