A New Zealander of Māori and Samoan extraction, Steven is best known for his arrangements and compositions of Pacific choral music. Tracing his family lineage back to his ancestral lands of the Hokianga in the north of Aotearoa, as well as to the Samoan villages of Sāfune and Sāmauga in Savai'i, and Vailoa (Aleipata) in Upolu, he was greatly influenced by the customs and music of both cultures. In particular his childhood involvement in traditional Samoan church life, through the insistence of his maternal grandparents, meant that music, both religious and cultural, was always a feature of his upbringing.

A graduate of the University of Auckland in vocal performance and choral studies, Steven has arranged and composed music for many notable national choirs including the New Zealand Secondary Students' Choir and the New Zealand Youth Choir. He currently works as a singing teacher, choral director, language coach (phonology and languages for singers), a professional singer, arranger, and composer in and around New Zealand.

Diana is a member of the NZ Association of Teachers of Singing, is an itinerant music specialist in Auckland, and amongst her other interests is Music Director of the Auckland Welsh Choir (Côr Cymraeg Auckland). As a New Zealander of Welsh heritage, Diana has been delighted to be introduced by the choir to the Welsh language through performance of traditional Welsh songs. She has always felt a special affinity for Celtic music, and in addition has continued to broaden the scope of repertoire. The result is a choir that is comfortable with a wide variety of genres.
