If a household cannot afford at least three of those items it is classified as deprived. Dr Boston said 18 per cent of New Zealand children were in households that poor in 2008, compared with 6-7 per cent in countries such as Sweden and the Netherlands.
It is fair to assume that many of that 18 per cent of children are also deprived of books, educational encouragement and other essentials for equal opportunities in life.
The solutions the group has proposed are mostly familiar: pay a child benefit to all parents, rich or poor ("dopey", as the Prime Minister said), re-allocate the present child-support payments to favour children under 6, extend income supplements for the low paid to unemployed parents, offer free meals in schools and provide after-school care.
But one suggestion is less known. The group suggests that when a couple with children separate and the parent left with the children has to go on the benefit, child-support payments made by the non-custodial parent ought to be passed to the household. People who have not been in that situation will be surprised that child support is not passed on; instead it is kept by the state to offset some of the cost of the benefit.
The group suggests, probably rightly, that if the payment was passed on, non-custodial parents would be more likely to meet their responsibilities. It also suggests that this should not mean a reduction in the benefit, making those households better off than children whose non-custodial parent is not making payments. That might not make society more equal but it would put some pressure on all earners to help their abandoned family if they possibly can.
Parental separation has been a prime cause of growing inequality in modern times. Living standards are now set by two-income households and divorce can deprive children of not just one income-earner but both if the custodial parent has to care for them full time. Family breakdown is a key factor in child poverty and even a part-solution there would be a start.
