Why dive here
With 46+ marine species recorded in the area - including blue sharks, great white sharks, seahorses and southern right whales - Dive Otago offers some of Fiordland's richest diving. Water ranges 12-17°C, warmest January, February, March.
Diving Fiordland is a different beast entirely. Forget your warm water corals; here we’re talking about an ecosystem shaped by glacial melt and tannin-stained fresh water sitting atop the salt. It creates this perpetual twilight zone, even at shallower depths. Dive Otago, one of the accessible sites, gives you a real taste of that unique environment. We love the strange, almost alien feel of the place, especially when you encounter the deep-water species that thrive in the gloom. You’ll see things like ghost sharks gliding past, their eyes reflecting what little light penetrates. Keep an eye out for the twisters, a type of large anemone, waving gently in the current. It’s a macro photographer’s dream with all the chitons – the snakeskin and blue green varieties are particularly striking. Honestly, the water itself often feels thick with the tannin, a sensory experience in its own right. We’d suggest going in the drier months, typically late autumn to winter, for the best chance of decent visibility, though "decent" is a relative term here. This site truly suits divers who are over tropical reefs and craving something genuinely unique, a dive that feels more like an exploration than a swim.
