The first opinion poll on the mayoral election in Auckland shows incumbent Len Brown has nearly three times the support of his nearest rival.
The UMR poll found 47% support for Mr Brown. Centre-right candidate John Palino has 14% and John Minto of the Mana party is on 5%.
Nearly a third of those surveyed supported none of the leading candidates or did not know.
The survey of 500 people was commissioned by Mr Brown's campaign. It was conducted in early August, with a margin of error of 5%.
