The city came in at least $10 million under its $43 million budget for hosting last week’s Asia-Pacific Economic Cooperation conference, city officials said Wednesday.

The unspent money included an $8.6 million APEC contingency fund that went untapped. The city also spent only $3 million for APEC-related insurance that had been projected to cost $5 million, Mayor Peter Carlisle said.

The total amount that the city spent on APEC could vary after departments calculate their expenses. But the police and fire departments did come in under their APEC budgets, said Police Chief Louis Kealoha and Fire Chief Kenneth Silva.

The police department alone had planned to spend $18 million for APEC, Kealoha said.

City attorneys also are considering seeking $7 million worth of federal funds to offset the city’s APEC costs, Carlisle said.

There were no APEC-related arrests and overall calls for police service fell 28 percent during APEC, Kealoha said.

At one point last week, there were three unprecedented days when no officers or civilian police employees called in sick, Kealoha said.

On the worst APEC sick day, "maybe five" HPD employees called in sick, Kealoha said.

"I’ve never seen anything like it before," he said.

Asked why police calls fell during APEC, Kealoha said, "Our culture is very embracing."

He described a police attitude toward APEC-related protests that "wasn’t adversarial," adding, "We were here to help you. … But you have to stay within the confines of the law."

Asked about what could have been done better for APEC, Carlisle cited "some of the behavior of some of the members of the Secret Service," adding, "I don’t think it’s a good idea to have people who are frowning all the time. I think we showed them what we can do here with a different way of thinking on the law enforcement side and I think the police department did just a magnificent job of it, magnificent."

Tim Hollern, assistant special agent in charge of the Secret Service’s Honolulu field office, said Secret Service agents acted professionally and respectfully.

"If we’re not smiling as compared with the Honolulu Police Department, our roles are a little bit different," Hollern said. "The partnership was very important and we were very happy with how the Hono­lulu Police Department and all the city partners engaged with the community to make this a successful event."
