NZ Moves to Protect Auckland and Coromandel Coastlines Amid Fears of Shellfish Over-Harvesting

“In recent months, there have been reports of intensive harvesting of an increasing range of species found in and around rock pools,” Ms Marcroft said.

The New Zealand Government has launched a major public consultation on new protections for shellfish and marine life across Auckland and the Coromandel, as growing concerns mount over the long-term sustainability of vulnerable intertidal ecosystems.

Oceans and Fisheries Minister Shane Jones announced that fisheries officials are proposing tougher management measures for intertidal species, including possible area closures, harvesting restrictions, and stronger protections for shellfish and other marine organisms found along some of the country's most heavily visited coastlines.

The proposals come amid increasing alarm from tangata whenua, coastal communities, marine conservation groups, and fisheries experts over the visible decline of shellfish beds and the intensifying pressure being placed on fragile coastal ecosystems by recreational harvesting.

"Fisheries officials have prepared proposals for better intertidal species management which will include options for area closures and additional restrictions on shellfish and some other species in these areas," Mr Jones said.

"Public consultation on the proposals start now and I encourage people to have their say during that process."

The review signals a broader shift toward more proactive marine conservation strategies as New Zealand grapples with rising environmental stress across coastal habitats caused by urban expansion, population growth, climate pressures, sediment runoff, and increasing recreational demand for kaimoana.

Intertidal zones — the areas between high and low tide — are among the country's most biologically productive marine ecosystems, supporting shellfish, crabs, sea snails, seaweed, and numerous species critical to coastal biodiversity and ecological balance.

Marine scientists warn that many shellfish populations, particularly in highly accessible urban coastal areas, are struggling to recover due to sustained harvesting pressure combined with declining water quality and habitat degradation.

Under-Secretary for Oceans and Fisheries Jenny Marcroft said communities have become increasingly concerned about the scale and intensity of harvesting activity occurring across Auckland and Coromandel beaches and rock pools.

"In recent months, there have been reports of intensive harvesting of an increasing range of species found in and around rock pools," Ms Marcroft said.

"Auckland's extensive coastline is close to a large urban population and beaches can be easily accessed, making kaimoana in the intertidal zone vulnerable to over-harvesting."

The Auckland region alone is home to more than 1.7 million people, placing enormous pressure on nearby coastal resources. Fisheries experts say urban proximity, combined with social media-driven gathering trends and improved access to remote beaches, has accelerated the depletion of some intertidal species.

Environmental groups have also raised concerns about the harvesting of previously overlooked species from rock pools, warning that removing large quantities of marine invertebrates can disrupt food chains and weaken ecosystem resilience.

Ms Marcroft said local engagement had highlighted strong public concern about the future health of these coastal environments.

"I have spent a lot of time speaking to locals around these intertidal zones and we share the communities' concerns about this issue. Officials have prioritised proposals to better manage shellfish and other sea life in these regions," she said.

"Intertidal shellfish and other invertebrates are an important part of coastal ecosystems and it's clear that people care deeply about their coastlines and the diverse marine life found there."

The consultation follows the Government's recent decision to impose a two-year ban on gathering sea life from rock pools and intertidal areas in the northern Hauraki Gulf, restrictions that came into force on 12 March.

Officials say early indications suggest strong public support and high compliance with the temporary protections.

"The restrictions already placed on shellfish-gathering north of Auckland have been welcomed by the community and there's been a high level of compliance," Mr Jones said.

Marine conservation advocates argue that temporary closures can be highly effective in allowing depleted shellfish populations to regenerate, particularly for slow-growing species that require several years to recover.

Internationally, coastal management agencies are increasingly adopting rotational harvesting zones, marine protected areas, and ecosystem-based fisheries management to protect biodiversity while still allowing sustainable public access to marine resources.

Auckland Minister Simon Watts said protecting coastal ecosystems was becoming increasingly urgent as shellfish beds in many parts of the region continue to struggle.

"Aucklanders are rightly proud of our harbours and coastlines. However, in many places, shellfish beds aren't recovering, and there is a lot at stake for the future of this resource," Mr Watts said.

"We are seeking feedback on proposed targeted protections — designed alongside local communities — to give these areas time to recover while also tackling pollution and runoff. We want your input on how to get this right."

Experts note that over-harvesting is only one part of the challenge facing shellfish ecosystems. Pollution, sediment runoff from urban development, wastewater contamination, and climate-driven ocean warming are also contributing to declining marine health across many coastal regions.

The Government says the consultation process is intended to ensure communities, iwi, recreational gatherers, and environmental stakeholders all have input into how future protections are designed.

Officials stress the goal is not to permanently restrict public access to coastal gathering traditions, but rather to ensure marine resources remain available for future generations.

"In considering potential changes to the harvesting rules, it's important that we get the balance right so people can continue to enjoy our coastlines for generations to come," Mr Jones said.

Public submissions on the proposed protections are now open through the Ministry for Primary Industries (MPI), with detailed information and consultation documents available on the agency's website.
