"It's largely the subterfuge employed by Mr Peters and his key enablers in transferring this wealth which is at the heart of this proceeding," Neil said.
The way Peters had organised his affairs before his bankruptcy allowed him to manage it on his own terms, Neil said. "He has not done his time," the lawyer said.
Before being declared bankrupt, Peters had given personal guarantees on loans when he was insolvent, including on finance for a Bentley Continental GT, Neil said.
Neil said Peters' actions were "unjustifiable" and his spending "extravagant".
The bankrupt's lawyer, David Chisholm QC, said the assignee was taking a "scattergun" approach in the case.
"We have a huge number of allegations, some of them minor, simply being thrown up, many of them based on theory rather than fact."
The key allegation seemed to be there was a conspiracy between Peters and his associates, which wasn't supported by evidence, Chisholm said.
Judge Abbot has reserved his decision.
