Haw. Rev. Stat. § 622-57
(c) In the case of a deceased person, a personal representative of the deceased person's estate may obtain copies of or may authorize the health care provider to release copies of the deceased person's medical records upon presentation of proper documentation showing the personal representative's authority.
If no personal representative has been appointed, the deceased person's next of kin in order of superseding priority, without court order, may obtain copies of or may authorize the health care provider to release copies of the deceased person's medical records, except as otherwise provided in this subsection and subsections (d) and (e). A deceased person's next of kin possesses superseding priority when all kin ranked higher in the order listed in the definition of "deceased person's next of kin" are deceased or incapacitated. When there are multiple persons at the same level of superseding priority, all such persons shall be entitled to request and obtain the records. The person claiming to be next of kin of a deceased person and requesting the deceased person's medical records shall submit to the medical provider from whom the records are requested, an affidavit attesting to status as next of kin with superseding priority. The medical provider may rely upon the affidavit, and in so doing, shall be immune to any claims relating to release of the medical records.
(d) Notwithstanding applicable state confidentiality laws governing the following types of specially protected health information, a health care provider may honor, in whole or in part, a request by the deceased person's next of kin for release of medical records if the medical records of the deceased person contain references pertaining to any of the following types of specially protected health information:
(h) For the purposes of this section:
"Deceased person's next of kin" means a person with the following relationship to the deceased person:
(6) A guardian at the time of death.
