HRS §414-214
How directors can give up their right to meeting notice
A director can give up the right to get a meeting notice, either before or after the meeting. The waiver must be in writing or sent electronically and kept with company records. If a director shows up and takes part, that also counts as a waiver unless they object right away.
The statute, as written — Waiver of notice of meeting
(a) A director may waive any notice required by this chapter, the articles of incorporation, or bylaws before or after the date and time stated in the notice. Except as provided by subsection (b), the waiver shall be in writing, signed by the director entitled to the notice or by electronic transmission by the director entitled to notice, and filed with the minutes or corporate records. (b) A director's attendance at or participation in a meeting waives any required notice to the director of the meeting unless the director at the beginning of the meeting (or promptly upon the director's arrival) objects to holding the meeting or transacting business at the meeting and does not thereafter vote for or assent to action taken at the meeting.
