Graham McCready has said pursuing private prosecutions against a senior police officer and the Prime Minister is not a waste of court time.
The retired accountant laid a prosecution against John Banks after police decided not to charge the former Act MP 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.
Mr McCready told Radio New Zealand this morning that his latest private prosecutions were against Prime Minister John Key and the police officer who led the investigation into Banks and did not lay charges against him.
He rejected claims the law suits were a waste of judicial time.
