In the Auckland District Court, Mr Wicks accused Mr Liu of preparing for the sting in February 2009 by visiting Kingsland's campus in Panmure under an assumed name with a would-be student, who he pretended was his daughter.
He returned with Ms Luo a month later to try to trick Han into temporarily putting the $3000 into Ms Luo's bank account, but Han repeatedly refused to co-operate.
Mr Wicks said eventually Mr Liu took out a white envelope containing $3000 and persuaded Han to give it to Ms Luo - who was out of the room at the time - as if it came from the Kingsland Institute.
Han, Mr Liu and Ms Luo then went to a nearby National Bank, where she deposited the money, produced a bank statement showing more than $10,000 in her account, then withdrew the $3000 again.
Mr Liu denied providing the money or receiving it back afterwards. He admitted visiting the school the previous month with a woman but could not remember her name or how he met her.
