Community events will include tapa cloth making workshops, combined church services, story telling and poetry sessions.
Hana Sevao, the Pacific liaison person from Otara library in South Auckland and co-ordinator for some of this week's activities, says the events attract people from other cultures who want to learn more about Tongan language.
Ms Sevao, who is Samoan herself, says celebrating Pacific languages in New Zealand helps raise awareness of other cultures.
