Te Tiriti o Waitangi 

Bicultural partnership is a vital component of environmental responsibility in Aotearoa New Zealand, and especially relevant to organisations providing social services and community development. The Place approach seeks points of connection between ecological and bicultural values in order to uphold Te Ao Māori and nurture cultural diversity in both word and action.

"From an environmental and spiritual perspective, Māori see the world as a unified whole, where all elements including tangata whenua, are connected. Emphasis is placed on maintaining the balance of cultural and spiritual values in the environment while using resources for commercial or social purposes. The changes brought on by a warming climate caused by human interference directly affect this balance."

"The Framework of the Treaty of Waitangi": Comment by Silvia Purdie
The Treaty is the framework of our place. It is the waha roa, the gateway into this place for those of us whose tipuna came within the last 180 years. It is the negotiated space of relationship, affection and battles that makes us who we are as kiwis. It is the marker post of land and the bedrock of river.
Four kupu form a tense and complex square dance: 'rangatiratanga', 'possession', 'kawanatanga' and 'sovereignty'. They tangle and push against each other, never resolved. At the centre is the land, this land, Aotearoa. As we consider our impacts on this land, for both good or ill, we are accompanied by Te Tiriti, and enter into its difficult dance.

"Interdependence": Comment by Patricia and Waiariki Grace
Earth, Sea, Sky: Images and Maori Proverbs from the Natural World of Aotearoa New Zealand, 2003, p.7
In the Māori tradition people are part of the universe, there being an interdependence among all life forms and all aspects of the physical and spiritual worlds. It is through care of, and respect for, the lands, waters and atmosphere that our physical and spiritual sustenance and survival is assured. Therefore there is a need for harmony with nature rather than attempt to conquer and rule it.

Huti te rito o te pū harakeke 
Kei whea te komako e kō?
If you cut the flax frond 
from where will the bellbird sing?
