National has raised questions about Government plans to develop the Crown-Maori Relations portfolio into a more formal partnership office.
Crown-Maori relations spokesman Chris Finlayson says it will raises expectations among iwi and Maori organizations that they will wield more power over Government policy.
"Is this agency really necessary?" Finlayson asked. "It is embedding a further layer of consultation and bureaucracy based along racial lines into everyday running of Government."
The partnership plan has not yet been signed off by Cabinet . But elements of it were referred to during speeches on Monday in the cabinet room during an event in which Prime Minister Jacinda Ardern and Crown-Maori Relations Minister Kelvin Davis hosted a partnership advisory group, including veteran activist Titewhai Harawira.
The original Crown-Maori Relations portfolio was set up by Ardern to take oversight of the 7000 or so commitments the Crown has made in Treaty of Waitangi settlements with iwi.
