This week, 150 years ago, Britain signed the Treaty of Waitangi with Maori chiefs, and the new colony of New Zealand was founded. In this anniversary year, many Maori people are angry. They feel the rights guaranteed them by the Treaty have been ignored, and that this is no time for celebration. To throw light on the current tensions, two young New Zealanders retrace their family stories. Charles Royal is a Maori, John McDonald is from a white settler family. Their findings reveal two very different views of history and of their land, and point to the difficulties ahead for this 'troubled paradise'.
