Haw. Rev. Stat. § 6
As soon as possible after the enactment of this Act, it shall be the duty of the President of the United States to certify such fact to the Governor of the Territory of Hawaii. Thereupon the Governor of the Territory shall, within thirty days after receipt of the official notification of such approval, issue his proclamation for the elections, as hereinafter provided, for officers of all State elective offices provided for by the constitution of the proposed State of Hawaii, and for two Senators and one Representative in Congress. In the first election of Senators from said State the two senatorial offices shall be separately identified and designated, and no person may be a candidate for both offices. No identification or designation of either of the two senatorial offices, however, shall refer to or be taken to refer to the term of that office, nor shall any such identification or designation in any way impair the privilege of the Senate to determine the class to which each of the Senators elected shall be assigned.
