Haw. Rev. Stat. § 36-23: Purchase of county bonds.

The director of finance, with the approval of the governor, may purchase bonds issued by the several counties in conformity with the law, or loan money to the counties on the security of the bonds out of any funds that may be available for such purposes, or accept the bonds as payment for property sold to the counties, whenever they may deem it for the public interest so to do.
