In the end on 19th century Presbyterian missionaries on Tanna Island,
created set of rules called Tanna Law. They wanted to destroy the foundation of traditional society. Festivals, rituals, dances and cannibalism were banned. "New order" was the western style of living and dressing. Local people could not accept this. In the beginning of 1940's Christian communities on Tanna collapsed. Villagers came to their roots and chose kastom, their traditional way of living. Today, there are many places to see kastom on Tanna. Various traditional ceremonies take place unplanned, when villagers decide, but throughout the year visitors are still able to see some kastom dances performed like centuries ago.
