Hawaii Revised Statutes Division 5. Crimes and Criminal Proceedings § 706-666

(1) An adjudication by a court of competent jurisdiction that the defendant committed a crime constitutes a conviction for purposes of sections 706-606.5, 706-662, and 706-665, although sentence or the execution thereof was suspended, provided that the defendant was not pardoned on the ground of innocence.

(2) Prior conviction may be proved by any evidence, including fingerprint records made in connection with arrest, conviction, or imprisonment, that reasonably satisfies the court that the defendant was convicted.
