Extending Māori Concepts in Secondary School Geography

open access: yesNew Zealand Geographer, Volume 82, Issue 2, August 2026.
ABSTRACT Secondary school geography brings together tāngata (people) and whenua (land), the central concepts of te ao Māori (the Māori world). Therefore, geography is ideally placed to respond to calls for mātauranga Māori (Māori knowledge) to gain “equal status” with Western knowledge.
