SkyCity spokesman Gordon Jon Thompson refused to comment on the fact a majority of the 750 people surveyed opposed the deal. However, he said it "doesn't make sense" to compare the June Herald-Digipoll survey with the one done last year.
He said the previous poll question allowed respondents the option of supporting the deal if the number of gaming machines in Auckland declined.
"It would have been more accurate to ask the same question again if you wanted to compare the results, especially given that the total number of EGMs [electronic gaming machines] has come down. The questions are clearly different and are unable to be compared."
While Prime Minister John Key has defended the deal on the grounds total pokie numbers in Auckland will fall, that decline is a result of local authorities' "sinking lid" policy for machines in pubs and clubs.
The survey comes as Mr Key - who conceived the deal with SkyCity bosses over dinner four years ago - faced questions yesterday from Greens co-leader Russel Norman over Transparency International's criticism of the arrangement.
Mr Key said he wasn't worried that Transparency International said the deal raised concerns about fiscal transparency, accountability, and regulatory issues.
"The reason for that is that this deal will be in full view for the public.
"We campaigned on the issue prior to the election.
"The agreement will be in the public domain when it is fully signed by both parties. The legislation supporting it will go through a select committee process."
Mr Key said Transparency International was wrong when it said the SkyCity project procurement process was severely compromised.
