Hamilton's Worldclear, set up in 2014 by former financial adviser David Hillary, provides foreign exchange and payment services to its customers.
In August last year, the company says that it employed Richard Whitham to help build relationships with local trading banks after difficulties with maintaining relationships with them.
When that approach didn't work, Worldclear changed tack and after discussions with Whitham decided to form a new company, T1 Holdings. This firm would open bank accounts and conduct financial transactions on Worldclear's behalf.
Over the following months, Worldclear paid money into T1 bank accounts and instructed Whitham to process financial transactions from the accounts on behalf of Worldclear.
Whitham, according to Hillary, also set up several Worldclear staff as users of the T1 accounts so they would have access.
By May 17 this year, T1 had 26 bank accounts with a total of $4.61m in them.
According to Worldclear, Whitham was in the office on that day processing payments but said he needed to leave early to deal with a personal matter and did not expect to be back the following day.
On May 18, Hillary says he sent a text to Whitham about two transactions due that day.
Whitham allegedly replied saying he was at the doctor but would be home soon.
According to Hillary, when his staff tried to access the T1 accounts but were unable to get in, he contacted Whitham again who said "that is weird" - and promised to check his own access when he got home.
Hillary sent two other messages to Whitham that morning saying "we need to talk" and "what is happening?"
After receiving no response to the messages, Hillary said he called the banks and was informed that the administrator of the accounts, Whitham, had removed Worldclear staff as users.
Hillary told the court he believed Whitham had left the country and remaining funds in T1's accounts could be in jeopardy.
Whitham told the Herald he had not taken any money, and was on a planned holiday which Hillary knew about.
"[Hillary] tried to contact me once to say 'where are you' but he knew exactly where I was, and next thing we knew our accounts were frozen," Whitham said.
