Jessica Ngatai, kaitakawaenga (liaison person/race relations conciliator) at the Human Rights Commission said Mrs Pihera-Ridge had been absolutely fantastic with the help she had given them.
Ms Ngatai said at the event Hemi Pirihi, kaiwhakarite (organiser) at the Commission, would explain the work done at the commission and how it related to the Treaty of Waitangi.
Commission senior legal advisor Michael White and Ms Ngatai will speak on the UN Declaration on the Rights of Indigenous Peoples.
Also speaking are Janell Dymus and Jason Mareroa, who are involved with Matike Mai Aotearoa, a constitutional transformation working group.
In mid-July and August New Zealand must provide a report on racial discrimination to the United Nations, Ms Ngatai said.
"The evening will also provide information and tools to support groups or individuals to begin preparing their own reports for the government, and have their say on the issue."
Mrs Pihera-Ridge will also perform with her husband, who is Native American, as their musical duo Native Nations.
She said their music represented who they were as indigenous people.
Ms Ngatai said the performance from Native Nations would "add a bit of flavour and diversity to the evening".
The event will be held at Te Ao Marama Hall in Ohinemutu on Tuesdayfrom 5.30pm to 8.30pm.
