The Auditor-General has criticised district health boards (DHBs) over the way they report on efforts to reduce Maori health inequalities.
A 2012/13 audit found while improvements had been made, many DHBs still needed to provide better information about what progress was being made to improve Maori health.
Assistant auditor-general Gareth Ellis said DHBs were vague about the initiatives they had implemented for Maori, with the one exception being Counties Manukau DHB, which served a high Maori population.
Mr Ellis said he expected to see better information on setting targets and reporting trends provided by the next audit.
That would make it easier for the auditor-general to assess how DHBs were performing, and how well various programmes and initiatives were working, he said.
The report gives examples of good practice but does not specifically name those DHBs which need to improve in relation to Maori health disparities.
Mr Ellis would not say which DHBs needed to improve.
