Why dive here
With 79+ marine species recorded in the area - including blue sharks, dolphins, hammerhead sharks, humpback whales and orcas - Nudibranch City offers some of Poor Knights Islands's richest reef diving. Water ranges 15-22°C, warmest January, February, March.
Nudibranch City, tucked away on the far side of Motu Kapiti, delivers exactly what it promises. We love how the relatively shallow reef here, maxing out at 20m, really lets you slow down and hunt. The steep walls still dominate, but pockets of shallower, sun-drenched coral provide perfect hunting grounds for those tiny, colourful slugs. We’ve spent entire dives just meticulously combing over a few square metres, spotting species we rarely see elsewhere. Keep your eyes peeled on those vibrant walls – you'll often find Mimic Blennies peeking out or the Flash-footed Shearwaters swooping overhead. The sheer variety of nudibranchs is what makes it a standout; it’s a site for those who appreciate the small wonders, for photographers wanting to get up close and personal, and anyone who enjoys a calm, rewarding search.
