Plans to focus development within urban limits have been given new emphasis by Mayor Brown, who proposed a modern, compact city built on improved public transport.
The commission's recommendations have stoked fears from some councillors and environmental groups of uncontrolled urban sprawl, which could choke Auckland's infrastructure.
Deputy Mayor Penny Hulse slammed the commission's report as "ideological nonsense" which failed to understand how modern cities developed.
She said the commission had ignored the Auckland Plan's proposal for 160,000 houses outside the urban limit, which would create a city bigger than Hamilton, Dunedin, Hastings and Palmerston North combined.
Ms Hulse said: "There is ample room to redevelop land that gives people the chance to live near to employment, educational or lifestyle opportunities. It is that demand, along with population growth, that is driving the market, not the cost of land at the boundaries."
The Auckland Council originally wanted to squeeze 75 per cent of the city's housing growth in the next three decades within existing urban boundaries. This was softened in the Auckland Plan to between 60 and 70 per cent - about 280,000 dwellings.
