Parliament has passed the Hauraki Gulf / T?kapa Moana Marine Protection Act — a once-in-a-generation milestone for the Gulf. The new law establishes 19 protected areas: 12 High Protection Areas, 5 Seafloor Protection Areas, and extensions to two marine reserves. Together, these protections lift the safeguarded area of the Gulf from around 6% to 18%.
It is a significant shift. By creating areas where damaging activities are curtailed, ecosystems are given the breathing space they need to recover. For the communities who live around the Gulf and the countless people who visit, fish, sail, and swim here, this change signals hope for a healthier future.
This milestone builds on years of patient work and the proposed protection areas are the result of an extensive consultation period. The Environment Select Committee considered submissions from 7,644 interested groups and individuals.
Beginning more than a decade ago, the Sea Change – Tai Timu Tai Pari marine spatial planning process mapped a path towards recovery. EnviroStrat’s CEO Dr Nigel Bradly led the writing team, while Rebecca Barclay-Cameron, now EnviroStrat Blue Ventures Portfolio Director, supported the Stakeholder Working Group.
Sea Change created a stakeholder Working Group comprising mana whenua, communities, environmental and recreational fishing advocates, scientists, and sectoral interests from aquaculture, commercial fishing, and agriculture. The Stakeholder Working Group was required to sit around the same table and work through many difficult trade-offs, none more challenging than the marine protection discussions that formed the basis for the new Act. Many of us working in the field of marine restoration, nature-based solutions, aquaculture, fisheries and kaitiaki will recall the process. It set a new precedent for collaborative marine planning in Aotearoa.
As Rebecca reflects: “Sea Change showed what patient, cross-sector mahi can unlock. Today’s legislation is one of the outcomes of that foundation.”
The Act demonstrates that collaborative planning, even when it takes years to bear fruit, can shift policy and change the trajectory of ecosystem management.
Among our work under ORA (Ocean Regeneration Aotearoa), we have established areas of reef restoration that will include some of the newly protected areas; many of which need active restoration The Bill allows activities for restoration purposes via a permitting system that supports the intended outcomes of the Act.
Why This Matters Now
Successive State of the Gulf reports have laid out the scale of ecological decline: overfishing, sedimentation, pollution, habitat destruction, and climate impacts. Shellfish beds have collapsed, kelp forests have been lost to kina barrens, and once-abundant fish species are under pressure.
The Act’s new protections mark an acknowledgment that incremental measures are no longer enough. By creating legally defined zones of high protection and seafloor protection, the Gulf now has the beginnings of a network of areas where ecological resilience can rebuild.
But protection on paper is only the beginning. What comes next — resourcing, monitoring, enforcement, and active restoration — will determine whether these protections deliver on their promise.
The Resourcing Challenge
Marine protection is often framed as a regulatory act — draw the lines, set the rules, and step back. But in practice, restoration is resource intensive. Monitoring compliance, enforcing rules and boundaries, measuring outcomes, and funding active restoration (such as reseeding kelp forests or rebuilding scallop populations) all require sustained investment.
Traditional public funding will not be enough to meet this challenge. That is why blended finance — combining public, philanthropic, and private investment — is emerging as a necessary tool to bridge the gap.
At EnviroStrat, this is where we see real opportunity. Through ORA, we are working on developing models for marine ‘nature credits’, designed to channel investment into initiatives that deliver measurable ecological outcomes. Nature credits can be a method to create a financial mechanism to reward biodiversity gains, restoration of reef systems, and water quality improvements.
As earlier noted, our pilot restoration sites are already underway. ORA’s 2ha reef restoration pilot venture in the Hauraki Gulf is testing how ecological uplift — such as increasing shellfish density or rebuilding kelp cover — can be quantified, verified, and translated into investable credits.
Other ORA ventures are contributing to regeneration:
Greenwave Aotearoa is advancing native seaweed cultivation, with the potential to scale regenerative ocean farming that both sequesters carbon and restores ecosystems.
Save Our Scallops is working to develop sustainable aquaculture pathways that can support both local supply and wild stock recovery, including scallop beds in the newly protected areas.
Together, these initiatives are designed to complement policy — turning legal protections into living systems that recover and thrive.
Shared Effort, Shared Outcomes
It is important to acknowledge that progress does not belong to one group alone. This Act is the culmination of tireless work by wh?nau, hap? and iwi leaders, environmental NGOs, researchers, rangatahi, kaitiaki, and many within government and industry. Without decades of pressure, advocacy, and stewardship, this moment would not have arrived.
The task ahead will require the same spirit of collaboration. To restore the health and mauri of T?kapa Moana, we need both the regulatory framework that Parliament has now created and the financial and practical mechanisms to make change real in the water.
The passing of the Hauraki Gulf / T?kapa Moana Marine Protection Act is a turning point. It sets the direction. Now comes the harder, longer journey: resourcing, monitoring, and restoring the Gulf at scale.
If done well, this work will not only bring back kelp forests, crayfish, scallops, and fish species — it will also strengthen the social and economic resilience of the communities who live alongside the Gulf.
EnviroStrat remains committed to supporting this journey — through strategy, investment, and action on the water. The Act is a foundation; what we build upon it will determine the legacy we leave.
Kia kaha, T?kapa Moana. The work continues.
In summary:
Purpose of High Protection Areas
- To protect and enhance indigenous biodiversity within the designated areas.
- Where biodiversity is already degraded, to support its restoration.
- To create spaces in the Hauraki Gulf where ecosystems can recover and thrive, free from human disturbance.
Prohibited Activities in High Protection Areas
Unless exceptions in sections 19, 20, or 21 apply, the following are not permitted:
- Fishing of any kind.
- Aquaculture activities
- Removal of non-living material such as sand, shingle, shell, or other natural matter.
- Dumping, depositing, or discharging waste or other matter likely to have more than a minor adverse effect on aquatic life.
- Introduction of any living organism (non-native or otherwise).
- Construction, alteration, extension, removal, or demolition of structures (including ships).
- Causing vibrations (except those from a ship’s propulsion) that could harm aquatic life.
- Disturbance of aquatic life, habitats, or the water column, including activities such as excavating, drilling, tunnelling, or dredging.
- Destruction or damage of the seabed or subsoil where it would have an adverse effect.
- Landing of aircraft within the area.
- Causing explosions of any kind.
- Mining activity.
