Abstract: The Well Child/Tamariki Ora Health Book (the Plunket book) is a small booklet given to New Zealand mothers on the birth of a child. Although use of the book has decreased since it?s inception in 1920, it is frequently kept within the family and handed on from mother to child. Utilising an oral history approach, this study has traced the development of the Plunket book over time and explored the experiences of a group of 34 women and one man who have reflected on their ownership of, or involvement with, Plunket books. The study found that the book remains an effective clinical tool for mothers and nurses. Nurses use the book as a tool to help develop a relationship with a mother and her family, and to identify and build on strengths. Mothers have used the book as a tool to link past with present, to maintain kinship ties across generations, to deal with change intergenerationally, and in a manner that contributes to their self-identity as woman and mother. The study recommends that nurses and other health professionals continue to use the Plunket book as a clinical tool mindful of the fact that the book remains in use beyond the health professional?s immediate involvement with the mother and child, playing an important role in the context of the New Zealand family across generations.
