In the wake of Kenoi's alleged misuse of a purchasing card issued by Hawaii County, Kim said on Thursday, March 3, 2016, that he had decided to run again, this time on a campaign to restore trust in government. He was elected mayor in primary voting on August 13, 2016, when he received more than 50% of the votes cast in a field of 13 candidates, thereby avoiding a runoff election in November. In keeping with a commitment he had made in every campaign to accept no more than a $10 donation from any individual, Kim spent a total of $21,931 in 2016, for a per-vote cost of $1.06. His nearest competitor spent $220,289, for a per-vote cost of $22.11.
