Muriwai refers to a confluence of two rivers, with the music of Ariana Tikao (Kāi Tahu) and Bob Bickerton coming together as a convergence of Māori and Celtic musical traditions through waiata, taonga puoro and Celtic harp.
These interlinked musical journeys through time and place begin with a Kāi Tahu creation story relating to water, moving through to the arrival of people in Aotearoa, our impact on the environment, and imagined consequences of our actions.
Muriwai Album
Muriwai, the album, is now available on Oro Records.
Featuring music from Ariana and Bob’s 2024 Chamber Music New Zealand Tour, the album explores a journey through time and place starting with a Kāi Tahu creation story relating to water, through to the arrival of people in Te Waipounamu, our impact on the environment, and imagined consequences of our actions.
Selected Tracks
In Concert
SOUNZ and Radio New Zealand recorded our concert in the Gillies Group Theatre, Whirinaki Whare Taonga, Upper Hutt, 10 October 2025. Filmed and edited by Chris Watson for the SOUNZ Films Project (funded by NZ On Air). Audio provided by RNZ Concert.
Elegiac, ethereal, and urgent, Muriwai carry the message for our times. Conduits for the instruments and voices of the atua, their work is a journey from the source towards the future we must urgently protect. This is both balm for the soul and a rousing call to action - Jacquie Boer

Adam Chamber Music Festival
The biennial Adam Chamber Music Festival has always been a supporter of both New Zealand composed music and taonga puoro practitioners and following an informal improvised session with wonderful Canadian clarinetist James Campbell in 2024, the festival invited us to perform a piece in 2026 and the result was Kahui Takitoru which was kindly filmed by Chris Watson at SOUNZ.
Given these uncertain times, the film certainly seemed to resonate with the audience given the standing ovation!
Ko Te Tātai Whetu
This work for taonga puoro and orchestra was written by Philip Brownlee and Ariana Tikao and was performed at the Nelson Centre of Musical Arts with the Nelson Symphony Orchestra conducted by James Donaldson on 27th July 2019.
Exhibitions
In 2016 we formed a rōpū with Robin Slow, Brian Flintoff, Holly Tikao-Weir and Solomon Rahui to create music soundscapes for a series of exhibitions. These exhibitions, all with a kaupapa Māori focus, have received critical acclaim with the exhibition Ngā Hau Ngākau touring around Aotearoa to various Art Galleries and Museums.
