Haw. Rev. Stat. § 49-19
In anticipation of the issuance under this chapter of revenue bonds theretofore authorized by the governing body for an undertaking or a loan program and of the receipt of the proceeds of the bonds, the county, with the approval of the governing body, may issue and sell revenue bond anticipation notes for the purposes for which the revenue bonds have been authorized, the maximum principal amount of which notes shall not exceed the authorized principal amount of the revenue bonds. The notes shall be payable solely from and secured by the proceeds of the sale of the revenue bonds in anticipation of which they were issued and the revenue, or the user taxes, or a combination of both, from which would be payable and by which would be secured those revenue bonds; provided that to the extent the principal of the notes is paid from moneys other than the proceeds of sale of the revenue bonds, the maximum amount of revenue bonds in anticipation of which the notes are issued that has been authorized shall be reduced by the amount of the notes paid in that manner. The issuance of the notes and the details thereof shall be governed by this chapter with respect to revenue bonds insofar as the same may apply, provided that each note, together with all renewals and extensions thereof or refundings thereof by other notes issued under this section, shall mature within five years from the date of the original note.
