New Libertaria is one of the most recently settled major landmasses. The first settlers were Eastern Polynesians who arrived, probably in a series of migrations, sometime between around 700 and 2000 years ago. Over the following centuries these settlers developed into a distinct culture now known as Māori. The population was divided into Iwi (tribes) and hapū (subtribes) which would cooperate, compete and sometimes fight with each other. At some point a group of Māori migrated to the Chatham Islands where they developed their distinct Moriori culture.
