Government and infrastructure

County government

Executive authority is vested in the mayor of Hawaiʻi County, who is elected for a four-year term. Since 2004, the election by the voters has been on a nonpartisan basis. In 2024, Kimo Alameda was elected mayor, defeating Mitch Roth in the general election. Legislative authority is vested in a nine-member County Council. Members of the County Council are elected on a nonpartisan basis to two-year terms from single-member districts. As of December 2016, Hawaiʻi County Council has a female supermajority for the first time, with six women and three men.

Administrative districts were originally based on the traditional land divisions called Moku of Ancient Hawaii. Some more heavily populated districts have since been split into North and South districts to make them more comparable on a population basis.

The number following each district is the Tax Map Key (TMK) number, used to locate state property information. They are assigned in a counter-clockwise order beginning on the eastern side of the island.

Nr.	District	Area mi2	Population 2000	moku	Map
1	Puna	499.45	31,335	Puna		District subdivision of Hawaiʻi County
2	South Hilo	394.38	47,386	Hilo
3	North Hilo	370.65	1,720	Hilo
4	Hāmākua	580.50	6,108	Hāmākua
5	North Kohala	132.92	6,038	Kohala
6	South Kohala	351.72	13,131	Kohala
7	North Kona	489.01	28,543	Kona
8	South Kona	335.38	8,589	Kona
9	Kaʻū	922.22	5,827	Kaʻū
	Hawaiʻi County	4028.02	148,677	6 moku

County council districts do not directly match the property tax districts because of the variation in the population density of voters in urban areas to rural areas; Hilo & Kailua (Kailua-Kona) towns are densely populated areas, while other districts such as Kaʻū, Puna, Hāmākua, and North & South Kohala are more sparsely populated.

Several government functions are administered at the county level that are at the state or municipal level in other states. For example, the county has its own office of liquor control.

State government

Hawaii Department of Public Safety previously operated the Kulani Correctional Facility in Hawaiʻi County, on the Island of Hawaii. In 2009, the Hawaii Department of Public Safety announced that Kulani Correctional Facility would close.
