An accident compensation expert is calling for ACC, health and welfare systems to be combined into one social insurance scheme.
Barrister and researcher Warren Forster said a unified scheme would provide a simpler, more sustainable social health system run by the government.
The provision of social services was inconsistent and incomplete, but it could be improved, he said.
People had to go to various departments for help with mental health and social support, which was incredibly difficult for those struggling the most, Mr Forster said.
Peoples' problems were exacerbated by a lack of communication between the departments - and a new system could rectify that, he said.
The public is being asked to have a say online about the scheme.
Once Mr Foster has the feedback, he will take his research to the government.
