An urban planning specialist believes Auckland's density plan is far too important to meddle with. 

The Government again revised the super-city's plan yesterday to reduce minimum housing capacity to 1.4 million. 

It's the second revision within weeks from the original two million after continued push-back in some suburbs.  

Mt Hobson Group's Hamish Firth told Mike Hosking the plan needs to be done by and for Aucklanders. 

He says it's been wrongly directed from the start, as it was lunacy to mandate two-million houses.
