A former chair of Health New Zealand says a fix to issues within health data systems has likely been put off, after a possible hack of MediMap. 

The platform's widely used across the country, especially in aged care, disability, hospice, and community health. 

Rob Campbell told Ryan Bridge there's a lot of issues within data systems that need fixing. 

He says it's expensive, can be complex and isn't headline grabbing, so it's the sort of thing people put off.
