The Government is offering Sky City an extra 350 pokie machines in return for a $350 million convention centre, Labour says.
Ministers won't comment on the negotiations, saying they're commercially sensitive, but Labour MP Ruth Dyson says Sky City wants 500 pokies and the Government has opened the bargaining with an offer of 350.
Approval was given seven months ago for Sky City's plan to build the convention centre in return for it being allowed to increase the number of gaming tables and pokie machines in its casino.
Opposition parties are fierce critics of what they call "chequebook legislation" and say the government is putting commercial interests ahead of public concern about problem gambling.
Ms Dyson, Labour's internal affairs spokeswoman, says it's a "really bad way" to conduct public policy.
"The social cost for Aucklanders affected by the ramifications of problem gambling will be significant," she said.
"Communities are already vehemently opposed to more pokie machines."
Sky City said earlier this month talks were continuing with the Government over the convention centre.
In addition to more pokie machines it wants an early renewal of its Auckland casino licence beyond 2021 and changes to gaming regulations.
It says the new centre will bring in about $90 million annually in additional visitor spending.
