On this journey he collected three skulls which he kept secret from Maori living in the region.
Two went to Karolinska Institutet, and the other went to the Anatomy Department in the University of Oslo, Norway. The skull housed in Oslo was repatriated in 2011.
Te Herekiekie Herewini, repatriation manager to Te Papa, said he had been in contact with the related iwi about the skulls.
Dr Eva Ahren, director of the Unit for Medical History and Heritage, was pleased the remains would be returning to their homeland.
"Karolinska Institutet takes very seriously our moral obligation to help repatriate remains of indigenous peoples from our historical collections. We greatly appreciate this opportunity to transfer the remains into the care of Te Papa's repatriation team."
The powhiri will be at Te Papa on May 29.
