This paper describes the size and shape of Māori tamariki (child) and taiohi (adolescent) traumatic brain injury (TBI) and reviews the wider international literature related to cultural factors and TBI. Scant research focuses on children and young people at highest risk of TBI. There is evidence of Māori tamariki and taiohi being significantly over-represented in TBI populations, with poorer outcomes including higher mortality rates. According to international research, ‘minority’ culture is a risk factor for certain causes of injury and a differential rehabilitation service response.
