"We felt it was premature at this point in the master-planning process." She said it could takes years to fill the old quarry for the rest of the planned development.
"How are you going to undertake a filling operation when you have people potentially living very close to where you are filling?" she asked.
"Fletchers says they have talked to their noise engineers and that's all going to be fine.
"I guess that's all stuff that will be teased out [in the planning process]."
Local resident Greg McKeown questioned the size of the site that he says is just 15ha.
"That's 100 apartments per hectare," he said.
"When Stonefields [another former quarry site] is completed, my understanding is that's going to come in at 20 to 25 dwellings per hectare, so the density from what I can see is four times the density of Stonefields."
Fletchers, the council and Housing Minister Nick Smith all refused to release details of the plan yesterday because it had not yet been signed off by the Governor-General. Dr Smith and Auckland Mayor Len Brown are due to announce the decision next week.
But Stuart Reed, whose Bed Factory store is one of five businesses that have been operating on the site, said Fletchers' planned apartments would rise four floors above street level along Mt Eden Rd, and eventually descend five levels below street level in the quarry behind.
"It's going to be like mole-dwelling," he said.
Henry Gough, who runs the next-door Eiffel En Eden cafe, said he refused a cash offer to buy out the rest of his lease, which runs until the end of this year.
"So many local people are worried about if the new residential project finishes, how many people are they going to bring in and the impact on traffic on the local roads," he said.
Ms Fairey said Fletchers originally proposed between 100 and 135 apartments in the special housing area, but had now reduced that to between 80 and 90.
