Have been scouting for some fresh Te Reo and I scored some! Me he te! (Like a boss!)
Kiwaha (which is kind of a Maori term for idioms - things that don't really make sense in translation so you just have to know them...).
Found this - which has the term in English, then in Maori , then a sound file to listen to!
Also some images from He Maori Ahau Facebook page
