Te reo Māori resources
I am still near the start of my own te reo journey, but have taken care to use accurate sources with the resources I have created.
Vocabulary lists and practice
A set of lists on a variety of topics to help build your vocabulary. Each list can be viewed, practised using flash-cards, or played as a card matching game.
For the matching game, when an English word or a picture is shown, say the Māori kupu to yourself, and when the Māori kupu is shown, just say it in Māori. This will help train your brain to be thinking in Māori, rather than constantly translating.
