Patrick Oki was the trusted leader of a prominent Honolulu accounting firm, but prosecutors say he stole more than $500,000 from the company by spending lavishly on himself.

KHON2 was there when Honolulu police arrested the 45-year-old Sunday.

The managing partner of the accounting firm PKF Pacific Hawaii was served with a 13-count indictment on charges of theft, money laundering, the use of a computer to commit the crimes and forgery.

Prosecutors say that in a three-year period, Oki spent tens of thousands of dollars of the company’s money on himself each month, and tried to pass them off as business expenses.

The office of PKF Pacific Hawaii is at the penthouse of 1132 Bishop Street. It has been named in publications as one of the best places to work as well as one of the largest CPA firms in Hawaii.

Prosecutors say from January 2011 to January 2014, Oki took advantage of his position and filed false reimbursement claims to the company of more than a half million dollars.

“As managing partner, he had a lot of trust and a lot of authority and the other partners didn’t question him initially and it wasn’t until the reimbursement request exceeded several hundred thousand dollars that they started to suspect that these may not be legitimate,” said deputy prosecutor Chris Van Marter.

Van Marter would not say what Oki spent the money on, just that tens of thousands of dollars were spent every month, and none of it was work-related.

“In effect, he was living a lifestyle well beyond his financial means even as the managing partner of PKF Pacific Hawaii,” he said.

Oki is also the treasurer of Ahahui Koa Anuenue, the fundraising organization of UH Athletics.

Spokesman Brandt Farias said in a statement, “Mr. Oki does serve as an uncompensated, volunteer board member and treasurer for Ahahui Koa Anuenue… Mr. Oki had no direct control or signing authority over any of our funds… no donor money was ever put at risk.”

Prosecutors say there is no evidence that Oki took money from other organizations outside the firm, but there could be other people involved.

“Based on the records that we saw, there were a number of false representations that involved other individuals besides just him, alleged clients who were receiving work when they weren’t,” Van Marter said.

KHON2 went to the Bishop Street office to see if anyone from the company wanted to talk. The answer was no.

Instead, we got a statement saying they’re going to be meeting with their attorneys in the next day or two and they’ll be in a better position to provide comment then.

Oki is scheduled to appear in Circuit Court on Thursday. If convicted, he faces up to 20 years in prison.
