Haw. Code R. § 8-19-14
School lockers provided to the students on campus are subject to opening and inspection (and external dog sniffs) by school officials at any time with or without cause, provided that the searches are not because of the student's race, color, national origin, ancestry, sex, gender identity and expression, religion, disability, or sexual orientation. Section 8-19-15 shall have no applicability to the opening and inspection (and external dog sniffs) of student lockers. None of the restrictions in sections 8-19-15 through 8-19-18 or related to general school searches and seizures shall in any way be construed to create an expectation of privacy in student lockers. Students should assume that their lockers are subject to opening and inspection (and external dog sniffs) any time with or without cause.
