Haw. Code R. § 12-51-12
If the director determines that an inspection or investigation is not warranted because there are no reasonable grounds to believe that a violation or danger exists with respect to a complaint under section 12-51-11, the director shall notify the complaining party in writing of that determination. The determination shall be without prejudice to the filing of a new complaint meeting the requirements of section 12-51-11(a). The complaining party may obtain review of the determination by submitting a written statement of position with the director. Upon the request of the complaining party, the director may hold a redetermining hearing in which the complaining party may orally present his views. After considering all written and oral views presented, the director shall affirm or reverse the prior determination not to conduct an inspection or investigation and inform the complaining party of the decision and reasons.
