I recently took a trip to New Zealand and ended up buying a book about the Māori language just to learn a little about the culture (I'm weird that way

) After reading through I was utterly confused, but I felt like learning more. I have read through several topics and have learned a lot, but I was wanting to know if there was anything online, preferably free, that I could use to get a more advanced knowledge of the language. Any help would be appreciated.
Thanks everyone
