The Neighborhood Commission Office, which administers O'ahu's 32 neighborhood boards, mailed 235,000 paper ballots to registered voters in neighborhood board districts and subdistricts that have contested races, a City and County news release aid. Voters may opt to fill out those paper ballots and return them by mail.

For the first time registered voters can also vote online by using a secure, 10-digit voter number that comes with the paper ballot, then vote at www.nbvote.com.

Voters in districts or subdistricts where there are no contested seats or no candidates may also vote online. In the past, mail-only elections, ballots were not sent to registered voters in districts that had no contests.
