Tohi Vagahau Niue, a significant new dictionary detailing the Polynesian language of Niue, will benefit Niuean studies for years to come. While its main aim is to be a repository for native speakers, it will also serve a wider linguistic audience, including comparativists and theorists in lexicography. Detailed 'user notes' introduce the reader to the basic challenges in Niuean lexicography and grammar.

With some 10,000 Niuean word entries, the present dictionary is a significant expansion on an earlier work by J.M. McEwen (1970), which featured some 4,000 Niuean entries. In addition, the English-Niuean finderlist, with some 4,000 English headwords, serves as an index to the riches of the Niuean language.
