This paper does not focus on the mining undertaken at Tui from the 1960s until Norpac ceased operating, but instead concentrates on its environmental impact. To clarify the struggles to prevent and then to rectify the pollution, the story is outlined chronologically. It is a story about a company seeking to avoid additional costs by evading, if possible, some of the environmental constraints that were imposed, and, once it abandoned the field, leaving the clean up to others. Not till the twenty-first century was the problem finally solved.
