In the June 2011 quarter, unemployment rates were 12.6 per cent for Maori, 13.7 for Pacific Islanders, 6.5 for Asian and 5.3 for European.
Admissions for socio-economically sensitive medical conditions - respiratory infections, gastroenteritis, skin infections - were higher for Maori and Pacific Island children than for European or Asian, the report found.
Dr Craig said admissions for those illnesses decreased for Pacific Island children in 2010. But more years of data was needed to be clear if it was a downward trend.
Auckland University department of paediatrics child and youth health head Professor Innes Asher said the slowing rate was encouraging, however by 2010 there were still about 4890 extra hospital admissions a year, compared with 2007.
The figures reflected a considerable extra cost to the health system and the children and their families.
"Greater attention needs to be paid to addressing the reasons why children fall ill in the first place," Professor Asher said.
"This means the provision of healthy housing through better heating and insulation, better access to GPs (including after hours), improving immunisation rates, and addressing New Zealand's high levels of child poverty."
