Te Umuroa was 25 when he died of tuberculosis on Maria Island, off the coast of Tasmania, in 1847.
He and six other warriors had travelled south to Porirua in 1846 to help Ngati Toa leader Rangihaeata resist European settlement. They were captured and accused of rebelling against the Queen's authority. They were tried in an English-language court martial, and five were sent to an Australian penal colony.
Te Umuroa died there the next year, and it was not until 1985 that his lonely grave was researched and his story discovered.
A team - including the late Ohakune tohunga Matiu Mareikura, George Waretini, Nohi Wallace and Joan Akapita - went to Tasmania to exhume

and recover his remains in 1988. They were brought back to Jerusalem for burial.
Te Umuroa was the father of one son, Rukuwai Paneta, before he left the Whanganui region. Numbers of his descendants, and the descendants of his warrior companions, were among the 200 people at the unveiling.
The youngest was one-year-old Rhythm Reeve, a seventh-generation descendant.
Descendant Aarena Allen lifted away the cloak covering the new tombstone and Bubs Rerekura, also a descendant, gave a small speech.
She said Te Umuroa was a courageous servant of his people, who stood against the tyranny of his time. He was wrongly imprisoned, and he and his fellows were later pardoned by the New Zealand government.
It was only much later that he was exhumed by his descendants, "who heard the pain of his longings".
"Escorted, returned and welcomed home to the tears of his people. Te Umuroa now finally rests in peace, in this, his final resting place."
The unveiling made for a big day for people of the river. At 9am visitors were welcomed on to Jerusalem's Patiarero Marae, where participants in the Whanganui River's annual Tira Hoe Waka spiritual journey had stayed the night. The crowd then travelled up Aorangi Rd to the small cemetery for the 10am unveiling, which was led by Turama Hawira and Father David Gledhill.
Everyone then returned to the marae, where Te Umuroa's family were called into the meeting house, Father Gledhill said some final prayers and people spoke to acknowledge what was achieved.
After that came a hakari (feast), with entertainment from participants in the Tira Hoe Waka.
