Well, after reading all three pages I am going to be a bit of a downer here. I have a master's in anthropology. I think the Maori thing works to a certain extent, if you buy in to the Jango/ Boba connection. In the first release of the films Boba Fett's voice was anything but Kiwi!
His voice was really evil and menacing but not New Zealander. I hate Karen Traviss' work because she is building on a mythology that was to never be. It's in the media of the era, it's in the movies.."no disintegrations!...As you wish" "he's no good to me dead!" etc. Boba Fett was never meant to be the major character he became in episodes 1-3. I think what George Lucas did with Boba Fett is so f,,, stupid. The more mysterious his character is the more impact it has. All of the "mando" crap that has evolved since Return of the Jedi is just fluff to me. And as far as canon goes...I dare anyone out there to tell me where it starts and where it ends. (I mean really, even if C-3Po's memory was wiped R2-D2's wasn't and they were both in the Death Star when Ben Kenobi became one with the force.)I would think that R2 just might have mentioned to 3Po that Darth Vader was his maker....)
But I digress ...there was never supposed to be a fully fleshed out "Mando" culture so I think it is cool to just leave it as it is.
