The identity of a Super City candidate charged with forging voting papers has been kept secret days before polling closes.

Two men have been arrested and charged with forgery after an inquiry into Auckland super city election enrolment irregularities.

John Banks admits he could lose the Super City mayoralty unless Auckland City and North Shore voters back him in big numbers.

I was beginning to like John Banks. Seriously. But then he reminded me last week why he shouldn't be mayor of a newly united Auckland Super City.

Len Brown is set to win the Auckland mayoralty by a landslide, unless John Banks can rally his half-hearted supporters to vote in the final days.
