I've never been overly into it, it's too close to Noah which i don't really like. However, just seeing this post made me think of it in a different way. In Maori, noa is the ability to reduce, neutralise, or convert tapu (tapu is 'closeness to creation' along a continuum of creation-reality-creation. Tapu things are variously regarded as sacred, dangerous, polluted or restricted. The word tapu (present in many Polynesian languages) is where the word 'taboo' comes from. Some things that are tapu are newborn babies, the dead (both crossing boundaries between reality and creation), and uncooked food). Anyway, women are one of the primary agents for noa (child-birthing women convert tapu to noa during childbirth, other women perform roles in conversion ceremonies).
I don't whether I've explained this very well, but I now like Noa a lot more, in the context of Maori culture anyway.
