Diving is the best way to explore this magnificent marine reserve. While in the water you may see stingrays, crayfish, octopus, seals sharks and over 100 other fish species.
Nature and conservation
The reserve’s name, Piopiotahi, means 'one native thrush'. The piopio (now thought to be extinct) was a ground-feeding bird that declined rapidly after the introduction of mammalian predators such as stoats and rats.
The reserve was established in 1993. It spans 16 km in length and covers an area of 690 hectares. The underwater habitats it covers are mostly deep muddy fiord basin, with a large section of deep reef and a small section of shallow rock wall along the shore.
There is very steep rock-wall on the inner northern side of Milford Sound which is dominated by delicate deep water invertebrates. These are animals that are fixed to the rock wall, including encrusting tubeworms, sponges, soft corals, colonial sea squirts, black coral and anemones.
On the Tasman Sea side divers can often get surrounded by schools of butterfly perch, hundreds of rock lobster and numerous reef fish. Octopus, stingrays, seals and occasional bottlenose dolphin also live in these waters.

Removing marine life
Members of Ngāi Tahu Whānui may access the reserve to remove pounamu provided they have any required resource consents and/or authorisation by the kaitiaki rūnaka. Pounamu must be collected by hand, with minimal disturbance to the site and only so much as you may carry in one trip.
Members of Ngāi Tahu Whānu are also permitted to remove deceased marine mammals and collect teeth and bones found within the reserves.
Take-off and landing of aircraft is permitted within the reserve.
There are specific no-anchoring areas in some of Fiordland’s marine reserves. These areas are home to particularly fragile species that could be damaged by an anchor or its swinging chain. Information about the no-anchoring areas in each of the fiords can be found in the Fiordland user’s guide (PDF, 4, 440K).
Recreational, educational and scientific activities
Recreational, educational and scientific activities are encouraged as long as they do not disturb or endanger the plant and animal life or natural features. A permit is required from DOC for any scientific research within the reserve.
Commercial rock lobster pot storage
Because of limited suitable space for storing rock lobster pots in Fiordland, five areas within four marine reserves are designated for commercial rock lobster fishers to store live lobster caught outside the reserve in holding pots and to store inoperable rock lobster pots (with doors open). These five areas are shown on the maps for the following marine reserves:
- Hawea (Clio Rock)
- Kahukura (Gold Arm)
- Taumoana (Five Fingers Peninsula)
- Te Tapuwae o Hua (Long Sound)
They are not open for use by recreational fishers.
Right of passage
Right of passage through the marine reserve is not affected by the reserve status of the area.
