But I can't find one.
A search of their site produced:
".... the best welfare program is a job..."
"I do think it is relevant to discuss people's lifestyle choices when these impact on government legislation and spending. The welfare review where, for example, the government has now become a front line dispenser of contraceptives (at taxpayer cost) and the marriage amendment legislation are two examples where people's lifestyle choices are part of the discussion."
" Children in violent families are at risk - welfare needs to be looked at."
ACT, by way of comparison, has a 5 page policy paper.
The Conservatives have said they can work with Labour. That would indicate they might support repeal of National's welfare reforms and even increased benefit payments. I remember United Future talked tough on welfare and then supported Labour removing the DPB work-testing National introduced in the late nineties.
Some greater clarity about where they stand shouldn't be difficult given their number 2 is an ex head of Work and Income.
