Auckland's Mayor's adamant he won't be drawing-up housing maps and plans for the Minister just yet

Housing Minister Chris Bishop's recently backed-down on Auckland's housing density plans, cutting the city's theoretical capacity from two million homes, to 1.6 million.

He's asked Auckland Council to send an updated summary on provisional zoning changes by March 17.

But Mayor Wayne Brown says they won't invest millions on maps without more clarity, and they don't materialise at the press of a button.

Brown says you're lucky to get an elevator by pressing a button at council, and anyone who thinks it's that simple is living on another planet.
