PM prosecution: Wolf of Wall Street DVD to be presented as evidence

Leonardo DiCaprio in The Wolf Of Wall Street.

A DVD of The Wolf of Wall Street will be introduced to court as evidence in a private prosecution against Prime Minister John Key and a senior police officer.

The movie represented the "lawless lifestyle of currency traders such as John Key where there are no rules, no respect for regulations and deals are made over the phone", serial litigant Graham McCready said.

The retired accountant was pursuing a private prosecution against Mr Key and Detective Inspector Mark Benefield, in the wake of a successful prosecution of former ACT Act MP John Banks.

Mr McCready laid a prosecution against John Banks after police decided not to charge Banks over his 2010 mayoral campaign donation return.

The Crown later took over the case, and after a trial in the High Court at Auckland, Banks was found guilty of knowingly filing a false return over donations from Kim Dotcom that were declared anonymous.

The latest prosecution against Mr Key and Mr Benefield, who led the police investigation, was because of the lack of police action into Banks' offending, Mr McCready said.

The Wolf of Wall Street's script mirrored the evidence emerging in the private prosecution, Mr McCready said.

"No doubt the usual bevy of QCs hired illegally at taxpayers expense to quash the prosecution will challenge the admission of this evidence."
