Taranaki iwi issued a trespass notice to Trans-Tasman Resources after its seabed mining proposal was rejected, marking a victory for indigenous and environmental opposition.

Iwi leaders in Taranaki have issued a trespass notice to seabed mining company Trans-Tasman Resources after it withdrew from New Zealand’s Fast Track process following a draft rejection of its iron sand mining proposal. The move, backed by environmental groups and the public, reflects sustained opposition since 2014 over concerns about Treaty of Waitangi rights, environmental harm, and lack of economic benefit. Despite attempts by the company and its parent, Manuka Resources, to pursue alternative routes, including seeking government funding and regulatory loopholes, legal and community resistance has blocked progress. The decision is seen as a victory for the people-powered movement, with calls for a permanent ban amid growing global interest in seabed mining.
