Before European contact, life in New Zealand was dominated by tribal warfare. Entire generations grew up amid battles fought for revenge, “mana”, and territory. Captives could be enslaved or killed, and in a lot of cases, eaten. Cannibalism, recorded in both Māori oral histories and early European journals, was a grim reality of pre-colonial existence.
Accounts from the late 1700s through the early 1800s describe battlefield feasts where the bodies of fallen enemies were cooked and consumed. This was not out of necessity; it was ritual. Eating an enemy was the Māori way, a way of asserting dominance and absorbing their strength - that’s what they believed anyway. It was also a reflection of how brutal life could be in an isolated land with no central authority or rule of law.
European observers such as Captain James Cook, Samuel Marsden, and later missionaries were appalled. Their reports spoke of villages surrounded by palisades, heads displayed as trophies, and raids that wiped out entire communities. It is easy to romanticise pre-colonial times, but the reality was violent and unforgiving.

Colonisation brought more than muskets and trade; it introduced a system of law and a moral code rooted in Christian teaching. Missionaries challenged practices such as slavery, infanticide, and cannibalism. British governance imposed consequences for murder and warfare. Over time, Māori themselves began to abandon the old ways, converting to Christianity and seeking stability through peace rather than endless utu.

By the mid-19th century, cannibalism had disappeared from Māori society. The shift was not only forced; it was embraced. Many iwi recognised that the world had changed and that survival now depended on education, order, and coexistence under a single legal framework.
Acknowledging this part of history is uncomfortable but necessary. The end of cannibalism in New Zealand marked a turning point, from tribal law to civil society. You can thank colonisation for bringing stability to this country and putting an end to the brutal and barbaric practices that once took place.
These truths need to be taught at schools - one of the most compelling reasons that so many tribes signed the Treaty. They wanted law and order and a better life.
Sadly education, order and co existence is sill wanting. I do not believe people in general accept the consequences of their actions (both Maori or others) and the rule of law is hanging by a thread. The big issue facing Maori, who want to revert to their old ways is victimisation and until they get over this and see the positives it will be more of the same I'm afraid. As in Singapore the consequences of this breakdown in law and society must be a return to capital punishment (for all).
