The cost of child poverty is estimated at somewhere between $5 billion and $10 billion a year.
Living in poverty means a great chance of a host of issues further down the line - health problems, higher unemployment, substance abuse, incarceration rates.
That's all in the future, but in the meantime one in 11 children are turning up to school without enough to eat, and if they aren't eating, they sure as hell aren't learning. What will that mean for their future prospects?
Earlier this week the Labour Party announced a policy to feed school children at a cost of $18 million. Hone Harawira has gone a step further - with a policy costing up to $100 million.
The Prime Minister has said that the private sector seems to be doing enough to meet the needs of children, and charity KidsCan says it can reach every hungry child in decile 1-4 who needs food - and it can do it for a fraction of the numbers being bandied about.
But it wants some help from the Government to do so.
Tonight, we hear that whatever the cost of providing food at schools may be, it's nothing compared to the future cost of not doing something.
