A Disability Survey released on Tuesday identifies 1.1 million New Zealanders as having a disability. This is up from 20 per cent in 2001.
The study found that 11 per cent of children are limited in their daily activities by a range of impairments. These ranged from minor learning impairments to serious physical conditions.
