NZ First Leader Winston Peters has accused the police of pulling their punches for political reasons in their initial investigation of electoral finance fraud allegations against Act MP John Banks.
Police last night refused to comment while the case is before the courts.
This year police found there was insufficient evidence to charge Banks, police minister from 1990-96, in relation to donations to his 2010 Auckland mayoral campaign.
However after private action brought by Wellington man Graham McCready, the Auckland District Court last week found there was a case to answer and referred the matter for trial in the High Court.
"Along comes a fellow and prosecutes it himself and he gets the judge to agree," Peters told reporters at NZ First's annual conference in Christchurch yesterday.
