Haw. Code R. § 16-99-7
The biennial renewal fee and completed renewal application shall be submitted on or before the commission prescribed deadline. Unless renewed, all real estate licenses expire at the end of every even-numbered year. When the renewal deadline falls on a non-working day, renewal fees paid by mail shall be considered as paid when due if the envelope bears a postmark of no later than the first working day thereafter. Failure to submit a completed renewal application and failure to pay the renewal fee when due, or if the check is not honored by the bank for whatever reason, shall constitute automatic forfeiture of license. The principal broker shall ensure that all licensees are currently licensed at all times during employment or association.
