However, in 1840 the Maori became unhappy with the terms of the treaty and they then stopped selling their land. European settlers were upset because they couldn't buy any land and it put pressure on the crown. The problems over the land caused the wars which lasted from 1845-1872. During these wars around 800 Europeans and 1800 Maori died.
Although the fighting ended, the problems over the treaty are still happening today which is resulting in the treaty settlements we here about in the news.
An effect of this treaty is education. This allows children to go to school and learn a whole bunch of new things and develop a whole bunch of new skills such as, reading, wrighting, maths ect.
Another effect of this treaty was building. Afew years after the treaty was signed, the Europeans started to build thing like houses, roads, schools, big buildings, ect. This helped with creating a bigger community.
Overal, the treaty of Waitangi has had the biggest effect on NZ history because without it we would not be here or have the things we have now like, roads houses schools, big buildings, ect.
