Hawaii Revised Statutes Division 3. Property; Family § 584A-704

(a) In any hearing or trial brought under this chapter, a report of the facts and results of genetic tests ordered by the court under this chapter shall be admissible in evidence by affidavit of the person whose name is signed to the report, attesting to the procedures followed in obtaining the report.  A report of the facts and results of genetic tests shall be admissible as evidence of parentage without the need for foundation testimony or other proof of authenticity or accuracy, unless objection is made.

(b) Documentation from a testing laboratory of the following information shall be sufficient to establish a reliable chain of custody and allow the results of genetic testing to be admissible without testimony:

(c) An alleged genetic parent or party to the parentage action who objects to the admission of the report concerning the genetic test results shall file a motion no later than twenty days after receiving a copy of the report and shall show good cause as to why a witness is necessary to lay the foundation for the admission of the report as evidence.  The court may, sua sponte or at a hearing on the motion, determine whether a witness shall be required to lay the foundation for the admission of the report as evidence.  The right to call witnesses to rebut the report shall be reserved to all parties.
