Auckland mayoralty polling

Horizon have released a exit poll showing only 4% behind in the Auckland mayoralty.

Before people get too excited by , I would point out Horizon's final pre-election poll in 2011 had Labour winning the general election and only 5% behind National (in they got 20% behind National).

An August UMR poll had the gap at 23% (47% to 14%).

Could things have changed that much in the last six weeks? We'll find out in a week when the results come in.
