Haw. Prob. R. app A R. R. 7
The mediator shall not communicate any matters discussed at the mediation conference to any court, except as allowed by the Uniform Mediation Act or other relevant law. Likewise, parties and attorneys are prohibited from informing the court of discussions or actions taken at the mediation except as allowed by the Uniform Mediation Act or other relevant law. This rule does not require the exclusion of any evidence otherwise discoverable merely because it was presented in the course of the mediation. This rule also does not require exclusion of evidence that is offered for another purpose such as proving bias or prejudice of a witness, negating a contention of undue delay, or proving an effort to obstruct a criminal investigation or prosecution.
