One of those aboard was Raymond Hall, the new kaihautu/chief executive for Ngā Tāngata Tiaki o Whanganui Trust, the Whanganui River governance entity.
He is from a Northland iwi "that holds an inherent connection to the Wairoa River". He understands the Whanganui Iwi connection to the awa (Whanganui River).
It has been a windy summer, and Potaka said the group had some windy days.
"There were a few challenges along the way. They were faced head-on."

The committee is already planning next year's voyage.
"We are just looking at what things we may improve on," Potaka said.
