Haw. Rev. Stat. § 571-73: No limitations on family courts.

Nothing in section 571-71 or 571-72 shall be construed to divest family courts of any of their powers, but the same shall specifically grant to the police departments of the several counties the power to take; detain; question; investigate; provide outreach, counsel, release, and follow-up services; and refer to appropriate social or other agencies, private or governmental, as the facts of the case appear to justify, minors coming within section 571-72, subject, however, to sections 571-31 and 571-32.
