Is Banksy secretly campaigning in Paekākāriki and Raumati?

Banksy? These question mark signs are popping up in Paekakariki and Raumati

With campaiging now well under way, we need to ask if the residents of the Paekākāriki-Raumti Ward have had some urban masterpieces secretly left in their rohe?  Along with the regular groomed headshots of candidates and views of Kāpiti Island from every angle are a series of hand painted original signs showing large black question marks.

Closer inspection does reveal that they are officially sanctioned posters from one of the candidates for the Paekākāriki-Raumati Ward.   In true Banksy style he has declined to be interviewed and asked for his name to be withheld.
