Nunuku-whenua
The Moriori, a Polynesian people, migrated to the then-uninhabited Chatham Islands from mainland New Zealand around the year 1500.[2][3] Moriori obeyed Nunuku's Law strictly, and maintained peace in the Chathams until 1835, when about 900 Māori from two North Island iwi, the Ngāti Mutunga and the Ngāti Tama, arrived in the Chathams.The invaders had guns and massacred the Moriori, who gathered urgently for a council at Te Awapātiki.Although youths argued in favour of armed resistance, elders ruled that Nunuku's Law could not be violated for any reason.He carved birds and seals on the walls of a limestone cave that still exist today.
