Māori, especially after 1830, were eager to have Europeans living on their land under their protection so they could benefit from European knowledge and trade. Missionaries on the other hand were keen to buy land so they could grow their own food to make them less dependent on tribal "protectors", who sometimes used food supplies to coerce them. Settlers allowed Māori to stay on the land they had "bought" and often continued to give presents to tribal chiefs, often prompted by the chiefs themselves, in order to maintain friendly relationships. These compromises stopped with the signing of the Treaty of Waitangi.
