This bill recognises that while Ngāti Kahungunu and Rangitāne are different groups and trace descent from different eponymous ancestors, they are also closely interconnected. Ngāti Kahungunu and Rangitāne share whakapapa and hapū affiliations throughout the Wairarapa and Tāmaki nui-ā-Rua regions. The term "joint redress iwi" is used to refer to Ngāti Kahungunu and Rangitāne in this bill.
