A permanent ban on seabed mining

In depth — from Te Pāti Māori’s policy document · 8 February 2026

Co-leader Debbie Ngarewa-Packer has reintroduced a member’s bill, the Seabed Mining Prohibition Act, to ban seabed mining permanently — closing all legal pathways including fast-track approvals, and applying across the coastal marine area, the exclusive economic zone and the continental shelf. It is the second version, strengthened to account for fast-track legislation; the first was supported by the Greens and voted down by Labour.

  • Back regenerative and sustainable approaches aligned with Māori values

How it would work

What the bill does

The Seabed Mining Prohibition Act would close all legal pathways for seabed mining, fast-track approvals included, and apply across the coastal marine area, the exclusive economic zone and the continental shelf — so the ban is defined by where the seabed is rather than by which consenting regime applies.

Why a second version

Ngarewa-Packer has introduced seabed mining legislation before. That bill had Green Party support and was voted down by Labour. This version is described as strengthened to reflect changes in the law since, specifically the fast-track regime.

The argument from the fast-track process

The case made is that the evidence is now settled because it survived a process designed to be permissive: even under fast-track legislation intended to push projects through, seabed mining was found to cause unacceptable harm to the environment, to taonga species and to tikanga Māori. The conclusion drawn is that these impacts cannot be conditioned away, and that where regulators themselves find the risk too great, Parliament should act.

Where it sits in their platform

Under a climate policy that commits to protecting whenua and moana from extractive industries, naming a seabed mining ban directly, alongside climate resilience investment for the communities most at risk and regenerative approaches aligned with Māori values. The framing offered is mana moana, kaitiakitanga and intergenerational responsibility.

In their own words

“The Seabed Mining Prohibition Act closes all legal pathways for seabed mining, including fast-track approvals, and applies across the coastal marine area, the exclusive economic zone, and the continental shelf.”

What the document doesn’t settle

Points the document defers or leaves undefined. These are gaps in the document, not criticisms of the policy.

  • The source is a press release announcing the bill; the bill text itself is not linked, so its drafting cannot be checked against the description.
  • A member’s bill depends on being drawn from the ballot, and the announcement does not say what happens to the policy if it is not.
  • Whether existing permits or live applications would be extinguished, and whether compensation would follow, is not addressed.
  • How the ban would sit with the Crown Minerals Act and the EEZ Act is not set out.
  • No exemption is described for scientific research, cable laying or other non-extractive seabed activity.
  • The announcement notes the previous bill was voted down by Labour but does not say what has changed to make a different result likely.
