Admin data quality for iwi affiliation in the 2023 Census

This is joint work with Walter Somerville, James Maguire, Pip Bennett

The iwi affiliation variable in the 2023 Census uses alternative data sources to replace missing values. This presentation takes a closer look into various aspects of quality for iwi affiliation data from the administrative (admin) data sources used, from the Ministry of Education (MoE) and the Ministry of Social Development (MSD), in a 2023 Census context. This is the first time that iwi affiliation data from these sources has been used for official statistics. This mahi was undertaken by Stats NZ and Te Kāhui Raraunga Charitable Trust, under the Mana Ōrite Relationship Agreement (MŌRA). The iwi affiliation variable is one of the highest-priority variables released in the 2023 Census. It is used to inform decisions that affect iwi and Māori, to provide iwi, iwi-related groups, and Māori with information to support their aspirations, and to meet the Crown’s partnership obligations under Te Tiriti o Waitangi.

The presentation “Methodology for iwi affiliation in the 2023 Census” by Walter Somerville, James Maguire and Roimata Timutimu outlines the entire methodology.
