Finance Minister Bill English has hinted at changes in the Budget to make it easier for housing developers to build smaller and cheaper.
He was critical yesterday of Auckland Council planning rules that require new apartments to be at least 40sq m and balconies at least 8sq m.
He said it was adding to the cost of housing - $80 a week to rental costs - and there would be more in the Budget on May 15 to help the supply of housing.
"There is a bit much of a mentality that a small group of people in a council know what everyone wants and needs and it turns out ... that those preferences of a small group of people about what the city should look like mean real costs for real households," he said in a pre-Budget speech to the Wellington Employers' Chamber of Commerce.
A range of other rules set minimum subdivision size, ceiling heights, bedroom size and even the width of the front.
