Wills also works as a paediatrician in Hawke's Bay. He said hospital wards were now full of poor, sick children every month of the year - not just in winter. There was no longer a "summer lull" in diseases.
"I do see parents who have made bad choices but most families on the hospital wards with sick children are spending their very small income very carefully," he said. "You don't get 10 to 12 people living in a two-bedroom house because they want to." The Government lacked "a plan" to reduce child poverty.
Papers released under the Official Information Act to Green MP Kevin Hague show the Public Health Advisory Committee recommended setting targets to reduce child poverty, in 2009. "Nothing has happened to that recommendation," he said. "They don't want to look bad."
Social Development Minister Paula Bennett, who appointed Wills as Children's Commissioner, is adamant child poverty has got no worse. "We are warming up their homes, we are getting them immunised, we are getting them into early childhood education, and we are making sure that we wrap support around those children who are most vulnerable - and that is making a difference," she told Parliament this week.
