The Protected Coast
The Te Whanganui-A-Hei Marine Reserve stretches along the Coromandel coast surrounding Cathedral Cove — a 840-hectare protected area where fishing has been prohibited since 1992. The marine reserve’s three decades of protection have produced a measurable recovery in fish populations (snapper are larger and more abundant inside the reserve than outside), and the reserve is now one of the most studied examples of marine recovery in New Zealand.
A marine reserve tour focuses on the ecological story — guided snorkelling or diving with a naturalist guide who identifies the species, explains the recovery, and contextualises the marine reserve concept (what protection does, how long recovery takes, what the reserve means for the wider fishery). The focus is educational rather than purely recreational — you snorkel the same reef, but the guide makes the biology visible.
The marine reserve boundaries extend from Motueka Island in the north to the southern headland of Hahei Beach — the entire Cathedral Cove coastline is within the reserve. No fishing, no collecting, no removal of any marine life. The rules are enforced and the community support is strong.
Frequently Asked Questions
What is different about snorkelling in a marine reserve?
The fish are bigger, more abundant, and less afraid of humans than on unprotected coastline. The ecological recovery is visible — snapper that would be rare or small on fished coast are common and large inside the reserve.
Can I fish in the marine reserve?
No — all fishing (recreational and commercial) is prohibited within the marine reserve boundaries. The prohibition is the reason the marine life has recovered.
Is the marine reserve tour suitable for children?
Yes — the snorkelling is in shallow, sheltered water and the ecological narration engages children who are curious about the marine life. Wetsuits and equipment in children’s sizes are provided.
