She said the study identified several factors that influence the likelihood of ongoing exclusive breastfeeding for wāhine Māori, including connection to te ao Māori.
The duration of exclusive breastfeeding was also found to be influenced by knowledge of the benefits of breastfeeding recommendations, how mothers felt about returning to work, and the incidence of maternal depression during pregnancy.
"I would like to see targeted resources aimed at early recognition and support of these wāhine Māori experiencing depression during pregnancy," said Dr Denise Bennett, a paediatrician and co-author of the study.
The study contributes to the body of evidence demonstrating the impact of colonisation on hauora Māori and how te ao Māori offers specific benefits for pēpi and wāhine Māori, she said.
"Colonisation has resulted in the loss of mātauranga Māori, including breastfeeding tikanga.
"Support for wāhine Māori breastfeeding needs to come from all of society, including government, employers, communities, whānau and wāhine Māori. Actions we take now will impact the hauora of wāhine Māori and pēpi in generations to come."
