"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.

[1] The first mention in print of the song is as a part of a set-list by a Māori performance group from Puketeraki (near Dunedin) being broadcast on the radio in April 1933.

[2] The Pātea Māori Club released a Pacific reggae/reggae pop version of the song as their fourth single in late 1985, entitled "E Papa".

During their 1984/1985 tour of the United Kingdom, the club performed the song on the UK children's television show Blue Peter.

During the tour, lyricist and mentor to the club's producer Dalvanius Prime passed away in late January, when the band had half-completed their album.
