A second Commonwealth Bank IT executive has been charged over a kickback scheme that allegedly involved $1.9 million in corrupt payments.
A tip-off led the Commonwealth Bank to look into the accounts of two IT executives last year.
Investigators uncovered suspicious payments that had been transferred into their accounts from an overseas company.
The IT executives, including 61-year-old Keith Robert Hunter, are accused of granting a US-based IT firm a lucrative contract with the bank without putting it to tender.
When the US Company - ServiceMesh - was sold for "hundreds of millions of dollars" in 2013, police allege Hunter and his 44-year-old colleague received payments.
ServiceMesh was headed by Silicon Valley entrepreneur Eric Pulier.
Hunter pleaded not guilty to bribery offences in a Sydney court last week.
At the time, police said they were looking for Hunter's colleague - a New Zealand national and IT engineer - who detectives believed had fled to the US.
On Thursday, the man turned up at North Sydney Police Station.
He was charged with seven counts of corruptly receiving a benefit and was granted bail.
He is due to appear in Downing Centre Local Court in May.
Both Hunter and the other man had their employment with the Commonwealth Bank terminated late last year.
The Fraud and Cybercrime Squad confirmed it is working with the FBI as the investigation continues.
