On 9 December 2011, the Electoral Commission referred the following matters to Police:

• An email sent by the Maori Party to supporters. It is the Electoral Commission’s view that the publication of this item constituted a breach of sections 204F, 204G and 204H of the Electoral Act 1993 because the item was an election advertisement that did not contain a valid promoter statement and was not authorised in writing by the candidate or the party secretary.
• Referral of an individual who is alleged to have voted using the identity of a friend. It is an offence under section 215 of the Electoral Act to vote as any other person at an election.
• An alleged attempted assault of an electoral official and damage to a Polling Place in Auckland Central on the afternoon of Saturday, 26 November 2011.
