What circumstances were most important in leading to treaty in New Zealand? How is the government in New Zealand helping to compensate the Maori for occupation of their land?

The circumstances that led to the Treaty of Waitangi were the British Colonization of New Zealand and the aboriginals willing to sell off their lands as a result of colonization. The government in New Zealand is helping to compensate the Maori for the occupation of their lands by addressing and solving their grievances through the Waitangi Tribunal and by deploying their machinery for the implementation of law and order.

Explanation:

In order to cease the aboriginals of New Zealand from selling their lands, the British representatives made a treaty restricting them from selling their lands to no one else but British representatives.
They made it clear in the treaty that the British Crown would take care of the protection and administration of the aboriginal tribes and treat them equally with all other New Zealanders.
