IS THERE A STATUTE OF LIMITATIONS ON A BENCH WARRANT IN HAWAII?

THE BENCH WARRANT WAS ISSUED BECAUSE THE PERSON DIDN'T SHOW UP FOR SENTENCING.. CHARGES ARE 2 CLASS C FELONIES AND 1 MIS/THEFT CHARGE.. NOW THE PERSON HAS NOT BEEN PICKED UP ON THE WARRANT FOR 6 YEARS AND HAS NOT BROKEN ANY LAWS IN THOSE 6 YEARS. I READ THE HRS STATUTES FOR THE CHARGES BUT I AM CONFUSED DUE TO THE PERSON NEVER BEING SENTENCED??? HELP..MAHALOS
