Restoring Sealife works with iwi, scientists, councils, and coastal partners to turn bare seawalls into habitat - and to show what changes when monitoring is built in from the start.
Across Aotearoa, our harbours and marinas are edged with smooth concrete and steel - seawalls, pilings, and breakwaters that provide almost zero ecological habitat. Where natural rocky shores once teemed with life, engineered surfaces offer nothing for marine species to cling to, shelter in, or feed from.
The Hauraki Gulf / Tīkapa Moana is facing depleted shellfish beds, disappearing seagrass meadows, and reefs overrun with kina - the result of overfishing, sedimentation, and the compounding effects of climate change. The Hauraki Gulf Forum's State of Our Gulf 2023 report describes continued ecological collapse across the marine park.
The Hauraki Gulf / Tīkapa Moana Marine Protection Act 2025, which came into force on 25 October 2025, establishes 19 new protected areas - two marine reserve extensions, 12 high protection areas, and five seafloor protection areas - and grows marine protection in the Gulf from 0.3% to 5.9% of its area.
Restoring Sealife focuses on retrofitting modular habitat onto existing coastal infrastructure and making the monitoring legible to the public. Third-party precedent work in Tauranga used Living Seawall Boulder products developed by Reef Design Lab and the Sydney Institute of Marine Science.
Habitat surfaces can add rock-pool texture and shelter to otherwise smooth coastal structures, with monitoring used to test what returns.
Seapods bolt directly onto existing seawalls, pilings, and breakwaters. No new construction needed - we work with the infrastructure that's already there.
Tauranga Harbour provides an external New Zealand precedent, with 100 installed pods and observed taxa including glass shrimp, cushion stars, bryozoans, ascidians, and triplefin fish.
Aotearoa's coasts are increasingly engineered, but hard infrastructure does not have to stay ecologically empty. Restoring Sealife exists to help coastal partners retrofit habitat into existing structures, translate monitoring into public understanding, and build restoration projects that are locally grounded, evidence-led, and transparent about what is still being tested.
Work with iwi, councils, and marine scientists to select priority sites where seapods will have the greatest ecological impact.
Engineer seapod configurations matched to each site's tidal range, wave exposure, and target species - customised for Aotearoa's marine environment.
Bolt seapods onto existing coastal structures - seawalls, pilings, breakwaters - with minimal disruption and no new construction required.
Track biodiversity gains through scientific monitoring, citizen science, and community engagement - measuring what comes back and telling the story.
Not every site shown here is at the same stage. Some are under active discussion, and some are future opportunities. We label each one clearly so visitors can see what is built, what is being monitored, and what is still at feasibility stage.
