This article explores how early childhood student teachers are developing competency to implement bicultural practices in New Zealand. It uses surveys and focus-group interviews to examine 162 student teachers’ understanding of the early childhood curriculum, and its implementation during their three-year degree initial teacher education programme. Results showed that the term “bicultural curriculum” was not well understood, and there was confusion over whether Te Tiriti o Waitangi or the Treaty of Waitangi forms the basis of the bicultural curriculum. Student teachers lacked confidence in competently using te reo (the Māori language) within their daily practices and articulating tikanga Māori (cultural constructs).
