The Treaty of Waitangi is the founding document of New Zealand and underpins the development of the New Zealand Disability Strategy. Making a World of Difference: Whakanui Oranga is consistent with the principles of the Treaty relevant to social policy, which are as follows:

Partnership: Māori and the Crown will have a relationship of good faith, mutual respect and understanding, and shared decision-making.

Participation: the Crown and Māori will work together to ensure Māori (including whānau, hap, iwi and communities) participate in the disability sector at all levels of decision-making around disability issues. Participation includes the right to self-determination and self-management.

Protection: the Crown actively contributes to improving the wellbeing of Māori, including support for independent living and the protection of Māori property and identity, in accordance with Māori values. Māori have the same rights and privileges as other citizens.

The New Zealand Disability Strategy Sector Reference Group has drawn on and learnt from these principles in developing its vision of a fully inclusive society.
