A case study can focus on a care institution, a setting, a particular theme or kaupapa, a systemic issue or a group of people/s. In selecting case studies within investigations, the Inquiry will apply the four general criteria above, and the following additional criteria:

• Diversity of care settings and subject-matter in each State and faith-based care setting investigation
• The scope (including number and nature) of allegations of abuse, and whether the proposed case study could be an exemplar of abuse occurring in the setting
• Whether a State or faith-based institution appears to have facilitated or failed to prevent abuse
• The likely availability of evidence including witnesses and documentary material to enable close examination of what occurred
• The extent to which there was accountability for alleged abuse
• Recognition and representation of Māori based on Te Tiriti o Waitangi and its principles
• National diversity – geographic range and ethnic, gender, social and cultural diversity should be represented
• Recognition and representation of disproportionately impacted peoples, such as Māori, Pacific, and people with disabilities
• Representation, visibility and participation of people with disabilities, people with mental illness, women and girls, and the LGBQTI/rainbow community in the selection of themes, issues and institutions.
