Why dive here
With 35+ marine species recorded in the area - including humpback whales, seahorses and sperm whales - Whalers Bay Kaikoura offers some of Kaikōura's richest reef diving. Water ranges 10-17°C, warmest January, February, March.
Whalers Bay is classic Kaikōura diving, and for us, it's a standout for a few reasons. The site sits just around the corner from South Bay, a quick boat hop, and immediately you’re into thick kelp forests draped over rocky reefs. It’s a completely different vibe than some of the deeper offshore stuff; here, the focus is on macro and the resident characters. We love finning slowly through the kelp, keeping an eye out for the Kaikoura-specific Pug-nosed Eels peeking from crevices, or the wonderfully camouflaged Snakeskin Chitons clinging to rocks. You’ll spot Wandering Anemones, Royal Albatrosses often soar overhead, and we’ve seen countless inquisitive New Zealand Fur Seals here. They absolutely own this bay, often zipping past or resting on the surface. Visibility averages around 6m, which sounds low, but it actually enhances the experience. It creates this atmospheric, moody environment, making every discovery feel more intimate. The sand channels between the kelp are worth exploring for crabs and unique pipehorses. This site suits divers who appreciate a slower pace, enjoying the hunt for smaller, fascinating creatures in a vibrant, cool-water ecosystem. It’s also incredibly sheltered, making it a reliable option when other sites are too exposed.
Safety Notes
