Recordings of taonga puoro that were made in the environment while they were on the river are interwoven throughout the album.
The members of Auaha are Ariana Tikao, Alistair Fraser, Elise Goodge, Matiu Bartlett, Brad McMillan and Te Paerata Tichbon.
They are from different backgrounds musically, but are drawn together by their common interest in taonga puoro (traditional Māori instruments).
Group members come from Whanganui, Wellington and Wairoa.
Their river guide and local musician, Charles Ranginui of Te Ātihaunui-a-Papārangi, also contributed a song to the album.
The recording and production was done by Sacha Keating of Te Aio Productions.
After three days' journey, the group alighted from the river and ensconced themselves at Koriniti Marae to complete recording of the new tracks.
As fate would have it though, the river began flooding again, and they had to evacuate and relocate to Whanganui or risk being trapped possibly for weeks.
Thanks to the Whanganui Musicians Club, Auaha were able to set up a new studio in the club's Drews Ave facility and finish the necessary recordings to complete the album.
"We were sad to leave Koriniti," says project co-ordinator and musician Elise Goodge.
"It was such a beautiful location to create and record in but the river had other plans. We are so grateful to the Whanganui Musicians Club for taking us in at short notice so we could finish the album.
"Somehow all the upheaval and excitement makes the album feel even more special."
Auaha will officially launch the album back in Whanganui on Saturday, July 8 at the Whanganui Musicians Club.
More information is available on Auaha's website and the album is available now to listen to and purchase on bandcamp.
