Applicants may need to show evidence of their disability if the assessor isn't familiar with the applicant's disability history. If this is the case, the assessor will ask the applicant's permission to find out more information about the disability. The applicant should give the assessor the name of their caregiver, ACC assessor, GP, specialist, physiotherapist, psychiatrist, social worker or occupational therapist. Refusal to cooperate with the assessor may prevent the assessor from completing the assessment and not allow the applicant to take part in the scheme.
