The Growing Up in New Zealand (GUiNZ) study is a longitudinal study of 6,000 mothers and their children, which began with pre-birth interviews in 2009. Because GUiNZ tracks families over time, it’s a useful way to learn about mothers.

Motu has conducted research based on the GUiNZ study and provided Manatū Wāhine with a series of reports and data. The data used for this report covers the whāea Māori in the study who were working before birth (318 wāhine total), and summarises outcomes based on maternal leave and return to work.
