Gerrard Albert is to speak to an international symposium about how the governance of the Whanganui River came to be returned to the river itself.
He will be one of four keynote speakers at the 20th International Riversymposium in Brisbane on September 18-20.
His talk is titled Tupua Te Kawa: The journey to return the Whanganui River to the Whanganui River.
It will outline how Te Atihaunui a Paparangi struggled to have their primary relationship with the river recognised for 150 years.
In 2008 it "unselfishly decided" to use its Treaty of Waitangi settlement to share its innate relationship with the river with all communities.
