Dr Smith said he would oppose appeals by the Three Kings United Group and South Epsom Planning Group, because of Auckland's need for more affordable housing.
But Mr Doig and Mr Wood said Dr Smith's move was extraordinary given that Conservation Minister Maggie Barry is also required to decide whether to approve a land swap proposed as part of the development, which would give up an existing reserve for housing in exchange for a new soccer pitch on the ground floor of the disused quarry.
"How can she possibly do that when the Cabinet, [which] she has collective responsibility within, has now taken an entrenched legal position on the development?" the men asked.
"Local residents have championed an alternative development plan from a leading landscape architect that would see a significant medium-density apartment development, integrated with the neighbouring town centre, and in sympathy with the adjacent Big King volcano," they said.
"An opportunity for an outstanding, integrated residential development is here, but it will languish in the courts while the developer, Auckland Council, and the minister collude to ram their preferred plan through. Our local board is willing to sit down and work through an agreeable compromise, but the minister will need to move into a more constructive mode."
