Mr Pierse described the Budget as "tragically disappointing" considering what is known about the impact of poor housing on children's health. He presented research which linked cold, damp, overcrowded, mouldy housing to 300 child deaths over the past 14 years.
He described New Zealand, and Northland, as having "three housing crises". "There are three overlapping - we have more people sleeping rough, when people are in housing it's poor quality, and, finally, we also have an affordability crisis."
Under the new Budget, Government spending on subsidised heating and insulation would reduce from $50,000 a year to $20,000 a year, Mr Pierse said.
He said he was investigating options via district council bylaws that would see the implementation of housing warrants of fitness - something central Government had dragged its heels on.
Mr O'Brien said while the Government had allocated $200 million over four years to reforming Child, Youth and Family, most of this was pre-existing funding that was essentially being shifted around.
"In terms of the really critical things, there's nothing there," he said. "Type 'child poverty' into a word search of the Budget. You'll get a blank."
The model for superannuation needed to be addressed urgently, as state sector funding had flatlined compared to GDP.
"[Superannuation] makes 42 per cent of the welfare budget. This will grow to 58 per cent by 2020. The implications for this in terms of child poverty are very clear."
