"E Papa Waiari" (English: "Oh, Uncle Waiari"), also known as "E Papa Wairangi" is a traditional Māori song, often used in tītī tōrea, a type of whakaraka (skill and dexterity game) played by passing tītī (40-60cm long sticks) while seated, in time to a rhythmic song.
The song became a staple for Māori musicians to record, including St Joseph's Māori Girls' College Choir Turakina Maori Girls' College Choir in the 1960s. In 1985, the Pātea Māori Club released the song as a reggae pop single, and the New Zealand band Herbs recorded the song as the opening track to their album Sensitive to a Smile in (1987), also in a reggae style.
