Dixon said in some instances documents provided by the defendant to TEL gave the impression someone unconnected to him was buying a property when in fact Mayer was selling it to himself.
Other purchases involved Mayer's alleged co-conspirator architect Simon Turnbull or people associated with him.
Dixon said Turnbull could not appear as a witness or a defendant as the man had left the country and his whereabouts unknown.
By disguising who was actually purchasing a property, Mayer was able to sidestep TEL's $4 million limit on what one individual person could borrow, Dixon said.
"This was a scheme designed to deceive TEL" Dixon said.
Mayer first went to trial in this case almost two years ago.
However, the proceedings were aborted over half a year later, before the case could be completed, due to Mayer's health.
