A crooked New York pension official hired by state Comptroller Thomas DiNapoli pleaded guilty Wednesday to steering billions of dollars worth of trades to brokers who showered him with cocaine, strippers, prostitutes and luxurious vacations.

Navnoor Kang, 37, copped to two out of six counts under a deal he hashed out with Manhattan federal prosecutors — just weeks before his Dec. 4 trial was set to begin.

“I recognize that I breached my duty to New York state,” Kang told the judge. “By doing so, I deprived those of rights to honest services … I am sorry for this.”

Kang said he engaged in the sordid bribery scheme while he was in charge of $50 billion worth of fixed-income funds for the state Common Retirement Fund — the nation’s third-largest public pension fund, which manages retirement funds for government workers, including cops and firefighters.

Specifically, Kang steered billions in fixed-income trades to two brokerage firms — FTN Financial and Sterne Agee & Leach — in exchange for lavish gifts from Greg Schonhorn of FTN and Deborah Kelley of Sterne Agee.

Schonhorn, for example, gave Kang “thousands of dollars” for strip clubs, dinners at upscale New York City restaurants, US Open tickets, Broadway shows and cocaine, the feds have said. Kelley, meanwhile, treated Kang to a ski weekend and a trip to New Orleans, as well as Paul McCartney tickets and meals, the feds have said.

Kang, who studied economics at Columbia University, faces as much as 25 years in prison when sentenced Feb. 23.

Schonhorn and Kelley have both pleaded guilty. Schonhorn, of Short Hills, NJ, had been cooperating with the feds and was expected to testify at Kang’s trial.​
