Hawaii is an open primary state. Voters are not required to affiliate with a party to vote in the primaries, but they must choose one party's ballot. The Hawaii State Constitution provides for the secrecy of the vote, including the voter’s political party selection.

Each registered voter will automatically receive their ballot in the mail approximately 18 days before each election. Voters who are away from their Hawaii residence during the election may submit an Absentee Application to have their ballot mailed to an alternate mailing address for the primary election, general election, or both. These requests are due no later than 7 days before Election Day.

You may be asked to provide one of the following valid forms of identification if voting in person on Election Day:

• Current driver’s license or state ID card
• A current utility bill, bank statement, government check, paycheck, or other government document that shows your name and address

A copy of ID is not required if you vote by mail, but the signature on your mail-in ballot must match your signature on file with the state.
