Growing Concern Over Pressure on Kai Moana Sparks Calls for Rāhui

Matthew Tukaki Posted On January 18, 2026

Concerns are growing among whānau, hapū and coastal communities across Aotearoa about the increasing pressure on sea life, as large groups of people gather kai from shorelines, rock pools and estuaries – raising fears that local ecosystems are being pushed beyond their limits.

From Tāmaki Makaurau to Te Tai Tokerau and the Bay of Plenty, residents say traditional gathering areas are being stripped bare, with pāua, pipi, kina, mussels and other taonga species disappearing at alarming rates.

Many whānau say the issue is not about any one community, but about scale, knowledge, and a lack of shared understanding around tikanga, sustainability and marine regulations.

“We’re seeing too many people taking too much,” says one kaumātua. “When the moana can’t recover, everyone loses – Māori, Pākehā, tauiwi, visitors, future generations.”

Community members report that large groups – sometimes arriving by bus or car convoys – are harvesting significant quantities of sea life in a single visit. In some areas, people say rock pools are being emptied entirely, leaving nothing behind to regenerate.

Environmental groups and marine scientists warn that coastal ecosystems are particularly vulnerable, especially in easily accessible areas close to urban centres.

While fishing rules exist, enforcement is limited, and many people gathering kaimoana may be unaware of size limits, daily limits, or the importance of leaving breeding stock behind.

For Māori, the moana is not just a food source – it is a living ancestor. The concept of kaitiakitanga places responsibility on tangata whenua to protect and sustain taonga for future generations.

As a result, some hapū are now considering or actively discussing the implementation of rāhui – a temporary prohibition on harvesting – to allow local ecosystems time to recover.

A rāhui is not about punishment, but about care, balance and protection.

“When things are taken without respect or understanding, rāhui becomes a tool to restore balance,” says a hapū spokesperson. “It’s about ensuring there will still be kaimoana for our mokopuna.”

Community leaders stress that rising tensions should not be framed as a racial or cultural issue. Instead, they point to the need for better education, clearer signage, multilingual information, and stronger public awareness about sustainable harvesting.

As Aotearoa becomes more diverse, many whānau say it is vital that new arrivals and visitors are supported to understand local laws, tikanga Māori, and the shared responsibility of caring for the environment.

“Most people don’t want to do harm,” one community advocate says. “But without guidance, harm still happens.”

With climate change, population growth, and increased coastal access placing further strain on marine ecosystems, hapū and iwi say the time for proactive action is now.

Calls are growing for stronger collaboration between iwi, councils, fisheries officers, and communities to protect vulnerable areas – before rāhui becomes the only option left.

As debates continue, one message remains clear: the health of the moana is inseparable from the wellbeing of the people, and protecting it is a responsibility shared by all who call Aotearoa home.
