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 less focused on learning reo, but has lots of useful cultural advice blended in.
Māori Television
Lots of content on Māori+.
For language learning in particular, check out Ako.
