Grant Kerr, Jetstar New Zealand head, said purchasing the carbon offsets would contribute to the airline's commitment to reducing its environmental impact.
"The Heritage Estate offers a unique blend of environmental, economic, social, biodiversity and cultural benefits to New Zealand."
Chief executive of Te Runanga o Ngati Awa, Enid Ratahi-Pryor said the relationship with Jetstar would enable the iwi to share its view of the world with others.
"Our view of the world is one that is filled with environmental consciousness, cultural integrity and the conservation and preservation of our lands for future generations."
Each year, Jetstar offsets all emissions associated with its business travel and vehicles operating on the ground.
The airline also has a fuel efficiency programme in place, targets to reduce electricity, waste and water consumption, and offers customers the ability to offset the emissions associated with their flight each time they book through its Fly Carbon Neutral Programme.
