I am still very much a beginner in my 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.
Useful resources
Some sites and a book that I think are helpful.
Te aka Māori dictionary
Te Aka Māori Dictionary is quite comprehensive for both Māori to English and vice-versa. Most words have audio, so you can hear the pronunciation from a native speaker. I find searching an English word doesn’t always give clear results. Often the most common word is not the first entry, which can be confusing.
Paekupu
Paekupu is an alternative to Te Aka. It also has audio and categorises words by area of knowledge. It’s great for technical words, but is not as comprehensive as Te Aka (yet).
Word of the day, and some grammar
https://kupu.maori.nz/ has a featured word of the day, lists of words, and grammar. I like the “kupu o te rā” (word of the day) which includes simple example phrases, and notes about the grammar and usage. There’s lots of good content around basic sentence structure as well.
Video and podcasts
Tōku Reo, http://www.tokureo.maori.nz, has lots of video content. It’s good, but I find the pace a bit slow and repetitive. Luckily, I can skip ahead when I feel like it.
I’m a big fan of the Everyday Māori Podcast https://www.everydaymaori.com/empodcast. Great kōrero and examples of language use. The early episodes are perfect for beginners and by season 2 things are up to more of an intermediate level.
Having listened to all of Everyday Māori (several times), I’m also now checking out Tāringa, https://www.taringapodcast.com/. It’s not as well structured, but does have some useful cultural advice blended in with the reo.
Māori Television
Lots of content on Māori+.
For language learning in particular, check out Ako.
Books
Raupō Phrasebook Of Modern Māori
I looked at a lot of different books, but found the Raupō Phrasebook Of Modern Māori to be the most useful. It’s not just a phrasebook. It provides a lot of insight into the language, the grammar, sentence structure. I highly recommend it (at least at this point in my learning).
