Haw. Rev. Stat. § 805-6: Arraignment.

Upon arraignment, the written complaint upon which the warrant of arrest or summons has been issued shall be construed, except upon motion of the accused or prosecuting officer, to be the charge, and the reading thereof shall be deemed waived. Unless a demurrer, motions, or other pleadings are interposed, the accused may be required to plead the accused's innocence or guilt immediately, if the accused appears to understand the charge against the accused.
