Prime Minister John Key says he does not need to read a police report into John Banks' mayoral campaign donations, as he continues to stand by his minister.
The police documents, reported on Thursday by the Herald, revealed that internet tycoon Kim Dotcom told police Mr Banks had asked him for two $25,000 donations for Mr Banks' 2010 Auckland mayoral campaign.
Dotcom said Mr Banks asked him to split his donation into two cheques of that amount so he would not have to declare where the money came from.
The police investigation found Mr Banks had filed a false election return but had not done so deliberately, because he did not read it before putting his signature to it. No charges were laid.
Mr Banks lost the 2010 mayoral bid and is now Act's MP for Epsom and Minister for Small Business.
