An MP wants all citizenship ceremonies to acknowledge Te Tiriti o Waitangi.
Green Party politician Catherine Delahunty has launched a member's Bill in a bid to change the Citizenship Act of 1977.
It would mean those taking part in the ceremonies would be told they are joining a nation whose foundation is a treaty between the indigenous tangata whenua and the Crown.
There would also be information read out about local iwi and hapu.
Ms Delahunty says that some new New Zealanders have asked to hear more about the nation's founding document.
Some immigrants have told her the lack of reference to the treaty is surprising and unacceptable.
Ms Delahunty says that she has found the reference to the treaty is missing from many induction ceremonies.
She hopes all parties will support her Citizenship (Acknowledgement of Te Tiriti o Waitangi) Amendment Bill.
Maori Party MP Te Ururoa Flavell is attempting to update another piece of legislation connected to the Treaty.
His private member's bill is aimed at giving MPs the option of swearing allegiance to the Treaty of Waitangi - as well as the Queen.
