An audit prompted by Hawaii County's problematic 2012 primary election found inadequate oversight, communications and documentation.
Hilo Councilman Dennis Onishi requested an audit of the 2012 election cycle because of concerns about overtime charges.
West Hawaii Today reported Tuesday the audit found a lack of supporting documentation for some transactions and overtime charges in both the county-run primary and state-run general elections.
Many Big Island polling places opened late on primary day, leading to the governor issuing an unusual proclamation to keep the island's polls open 90 minutes later.
The state took over management of that year's general election.
The audit found that the 2012 cycle cost $1.5 million, compared to $1.8 million for the 2008 election.
Council members say it's more important elections are conducted correctly than cheaply.
