HRS §414D-146
When directors can give up their right to meeting notice
A director can choose to give up the right to receive a required meeting notice. The waiver must be in writing and signed, unless the director shows up to the meeting. Showing up counts as giving up the right unless the director objects at the right time.
The statute, as written — Waiver of notice of meeting
(a) A director may at any time waive any notice required by this chapter, the articles, or the bylaws. Except as provided in subsection (b), the waiver shall be in writing, signed by the director entitled to the notice, and filed with the minutes or the corporate records. (b) A director's attendance at or participation in a meeting waives any required notice of the meeting unless the director at the beginning of the meeting or prior to the vote on a matter not noticed in conformity with this chapter, the articles, or the bylaws, objects to lack of notice and does not thereafter vote for or assent to the objected to action.
