New Zealand's Kelp Forests

Macrocystis pyrifera is commonly know as bladder kelp. With each strand growing up to 20 meters long, it grows in thick clusters, sometimes spanning kilometres. These areas are the kelp forests which provide some of the best snorkelling and diving in New Zealand.

These Macrocystis kelp forests grow mainly in the South Island. The further South you dive, the thicker and more prolific they become. Because of the exposed nature of the East and West Coast, opertunities to dive kelp forests with good conditions can be rare. However in the protected inlets and bays of Stewart Island's East Coast, conditions can be consistent and the water is clear.

In the kelp forests of Patterson Inlet grow 269 species of native seaweed. So under and amongst the kelp lies a magical kelp garden, bustling with busy life. Many species of small fish dip in and out of the kelp and rocks, while larger Moki, Cod and Greenbone cruise cautiously through the kelp. In the rocks lie Kina, Paua, Crayfish and Octopus. Occasionally a curious sealion will come to investigate before it cruises onwards.

The marine reserves of Ulva Island provide the best snorkelling and freediving opportunities. Packed with life, they are mysterious and wonderful places to visit. Truly amongst the best snorkelling experiences in New Zealand, Stewart Island provides an unforgettable adventure for all ranges of experience and skill.
