The Ngāti Tuwharetoa ki Kawerau iwi places great significance on Te Kete Poutama, an area that encompasses Lake Rotoitipaku near Kawerau, because it has been integral to their economic, cultural, spiritual and social wellbeing for generations. Tasman Pulp and Paper, now Norske Skog Tasman Ltd., leased the area for dumping waste in 1971 and it became the primary disposal site for solid paper-mill waste. Now Lake Rotoitipaku no longer exists – it’s filled with more than 600,000m3 of toxic material. In 2013 the dumping will stop and the land will return to its trustees.
