Ta Moko is a very complex issue and I can recommend this link
history-nz.org/maori3.html
(but can not make it a link due to my very bad computer skills) read the mans face and then look at him again - the site shows you an outline of what the ta moko means.
Oh, (going week at the knees) yes ta moko can be on the body too :)
To me she is beautiful, the essential picture of a Moari Woman.
Ta moko rose in interest again during the 60's when black power became active in New Zealand. It became a symbol of the wearers strenght to regain their land, artifacts and human remains taken from them.
The strangest thing is that, when you first meet someone with Ta Moko its all you see when you look at them; yet, I recently painted a picture of my friend who has Ta Moko, and it was my Euopean friend that noticed, I painted him without Ta moko, I had not seen it, I had just seen him. It was the first time I had knowingly seen him without Ta Moko.
I think in Europe we see Ta Moko as tats which hold a whole different meaning here. When my friend comes to Ireland, we find it difficult to eat out, get into a pub and we are always the centre of attention as we are presumed to be up to no good LOL. In new Zealand, no one notices.
Sorry, didn't mean to hijack the thread, did I say ta moko is an obsession of mine :)

Body Ta moko :)
