Generally, its 'kirituhi', pretty design that looks the part.

As I understand it, kirituhi used to mean the process of applying a moko design in a non-permanent manner (charcoal IIRC) which, though not insulting, wasnt considered to be of any significance or to carry any prestige (mana).

The meaning of the term 'Kirituhi' has been extended to include moko-like designs that have no particular meaning (and are therefor not insulting to anyone except the purists)
