At the risk of perpetuating this unfortunately wide thread, I was stunned to read in the page you linked to that, " The pattern is based on one used for penguins in the northern hemisphere, only smaller. "It was re-designed for the little penguins in the southern hemisphere," said Castle."

What penguins in the Northern Hemisphere? A quick search at Britannica.com yielded this excellent page

The comment seems particularly odd given that the two largest types of penguin are both exclusively Antarctic and sub-antarctic dwellers. I read once that all but one of the 16 species of penguin can be found in NZ waters, so I was surprised to read the statement about "larger penguins from the North."
