The state government will reverse funding cuts to dozens of organisations that advocate for people with a disability, after sustained pressure from groups that faced collapse.

NSW had ruled out maintaining $13 million a year in funding for advocacy groups once the state government transfers its disability services spending to the National Disability Insurance Scheme (NDIS) in July.

The national scheme will give some people with a disability direct funding support but not for the groups who advocate on their behalf.

Up to 50 disability advocacy groups faced closure without funding.

The cut was expected to wipe out up to 50 NSW advocacy groups, including the 60-year-old NSW Council for Intellectual Disability.
