New Zealand has passed the Hauraki Gulf / Tīkapa Moana Protection Act 2025 , a law that greatly expands marine protected areas in the Hauraki Gulf to help restore its health.

What the new law does

  • Renames and updates protections as the Hauraki Gulf / Tīkapa Moana Marine Protection framework, described as the most significant increase in marine protection in over a decade.
  • Nearly triples the area under strong protection in the Gulf, creating 19 new protected areas in total.

Key protections in the Gulf

  • Extends two existing marine reserves (such as Cape Rodney–Okakari Point/Goat Island and Te Whanganui-o-Hei/Cathedral Cove), where removing marine life is banned.
  • Establishes 12 High Protection Areas , where most commercial and recreational fishing and other extractive activities are prohibited to allow ecosystems to recover.
  • Creates 5 Seafloor Protection Areas , which ban bottom‑contact fishing methods so seafloor habitats can regenerate.

How this helps restore the Gulf

  • The law targets long‑term problems like habitat loss, kina barrens, depleted shellfish beds, and seafloor damage by reducing direct human pressure on critical habitats.
  • It is part of the wider “Revitalising the Gulf” programme, which aims to restore biodiversity and support New Zealand’s goal of protecting 30% of its oceans by 2030.

Ongoing debates

  • Supporters see it as a once‑in‑a‑generation step that finally gives the Gulf space to recover ecologically.
  • Critics argue that carve‑outs for some commercial fishing and limited funding could weaken its impact, so they are calling for stronger and more consistent rules over time.
