A United Nations human rights investigator will meet several MPs at Parliament on Tuesday before going to Auckland.
Professor James Anaya, who is the UN's special rapporteur on human rights and indigenous people, is in New Zealand for a week, and will attend a hui at Te Tii Marae at Waitangi on Wednesday.
A visit by a previous UN rapporteur in 2005 resulted in a report that was critical of some Government policy, including the Foreshore and Seabed Act.
Prime Minister John Key says his meeting with Professor Anaya went well.
But he says whether New Zealand's race relations policies are working well is actually a test for New Zealand people, not the United Nations.
