PUKAPUKAN is more like the Samoan language than Cook Islands Maori and is completely unintelligible to most other Cook Islanders. Remarkably though, there are more speakers outside Pukapuka than on the Northern Group island. It's estimated 2,300 people are fluent, with the majority in Australia and New Zealand. Until December, 2007, there was no known written form of the language. The very first work to be created was a translation of the Bible's New Testament which is still only in a draft form.
An example of Pukapukan: Ata wai wolo = Thank you
