Two polls released today have Len Brown well in front of John Banks in the race to become Auckland's super city mayor.
Mr Brown, the Manukau Mayor, had a substantial lead over Mr Banks among those who have already voted and those who have yet to do so in a Horizon poll.
Of those who had voted, Mr Brown led by 56 percent to 22 percent, the Horizon website says. The figures are 40 percent and 18 percent among those yet to vote.
Conservative candidate Colin Craig was third with 11 percent support of those who had already voted and 8 percent of those who had not.
The poll of 307 who had already voted has a margin of error of plus or minus 5.6 percent. The poll of 356 who have yet to vote had a margin of error of plus or minus 5.2 percent.
As well as being ahead in Manukau, Mr Brown also led in Franklin, Waitakere, Papakura and even Auckland City, where Mr Banks is currently the mayor.
Mr Banks was ahead in Rodney district and the race was close in North Shore, the poll said.
Polling also showed Mr Banks was only marginally ahead among National Party supporters who had already voted (38 percent to 36 percent), and behind among National Party supporters who had yet to vote (29 percent to 35 percent).
Meanwhile, Mr Brown had 56 percent support in a Herald on Sunday-Phoenix Poll of 893 Aucklanders who had already voted or said they would definitely or probably vote.
Mr Banks had 33 percent support, but he said his own polling showed the vote was close.
The poll had a margin of error of plus or minus 3.3 percent.
Postal votes must be mailed in by Wednesday but votes can be handed into libraries by noon on Saturday.
