The Maori name for the yellow-eyed penguin. It is also the maori name for horse, according to my Maori-English dictionary. Go figure.
Of course this is also the cute fella that Linus fell in love with (it bit his hand) in Australia and subsequently became the mascot for linux. It is more commonly found in New Zealand, where it can make a nuisance of itself by nesting under your house. It seems to know that it is a protected species too.
