Site Overview

Labrid Channel is the premier drift dive at the Poor Knights Islands Marine Reserve, where the narrow channel between the main islands funnels the tidal current into an exhilarating underwater ride past walls of schooling fish and colourful soft corals. The channel acts as a natural highway for marine life, with kingfish, trevally, and barracouta using the current to patrol between the islands in search of smaller fish that shelter in the channel walls. The water clarity in Labrid Channel is often exceptional, with visibility exceeding 30 metres on good days, allowing you to see the full scale of the schooling fish aggregations stretching away in all directions. The drift dive format means that you simply relax into the current and let it carry you past the action, conserving air and energy while the marine parade unfolds before you. The channel walls are covered in soft corals, black coral fans, and gorgonians that extend their feeding polyps into the current, creating a living tapestry of colour and movement. Pink maomao and blue maomao fill the mid-water column in vast schools, while the larger predators patrol the edges. The drift typically covers several hundred metres of channel, passing multiple pinnacles and reef structures that each attract different concentrations of marine life. The combination of effortless drift diving, crystal-clear water, and abundant pelagic action makes Labrid Channel one of the most exciting and accessible drift dives in New Zealand.

Dive Briefing

"The dive begins at the southern entrance to Labrid Channel at approximately 5 metres, where you orient yourself with the current direction before descending into the main flow. The current typically flows from south to north through the channel at moderate to strong pace. Relax into the drift and maintain neutral buoyancy as the current carries you along the channel walls. Schools of kingfish appear within the first few minutes, growing larger and more concentrated as you drift deeper into the channel. Trevally and barracouta join the kingfish in the mid-water column, hunting the smaller fish that shelter near the walls. The channel walls are covered in soft corals and gorgonians that extend their polyps into the current, creating a colourful backdrop for the schooling fish. At 15 to 20 metres depth, the current accelerates around pinnacles and point features where the largest concentrations of fish gather. Maintain awareness of your depth and air supply as the drift can carry you deeper than expected. Deploy your DSMB at the end of the planned dive time and ascend in the current while the boat follows your marker for pickup. The safety stop is conducted in open water with the current."
