We also spent some time visiting Te Ana a Nunuku, known to Moriori as Nunuku's cave. Nunuku was a man of great significance for the people of Moriori. He outlawed fighting amongst inhabitants on the island and is responsible for introducing Kawenata Rongo o Nunuku Whenua, the Covenant of Peace of Nunuku Whenua—a significant aspect of tikanga Moriori. I think it impressed all of us, looking at the significant limestone etchings at the entrance to that cave and reflecting on the history of the island.
