Boyd Remembrance Committee chairman Terry Smith said the plaque had been returned for "all those that have suffered in one form or another, from the silencing of local histories and to the misunderstanding between peoples and cultures" in the 208 years since the Boyd.
"This is another milestone in our ongoing journey, Maori and Pakeha working together building relationships founded upon reconciliation and forgiveness," he said.
The event continued to be misrepresented despite efforts in recent years to bring the stories of local people into the open. Those efforts included the Boyd remembrance weekend of 2009, the 200th anniversary, with its focus on healing and building relationships.
Those involved in the 2009 event included descendants of Betsy Broughton and Anne Morley, survivors of the tragedy.
"It was an opportunity to reflect on Maori and Pakeha relationships 200 years on and the continuing journey together has strengthened our relationships and unity," Mr Smith said.
