Underwater Photo Location: Northern Arch, Tawhiti Rahi Island, Poor Knights

How Hot is this Dive Site? click a star to rate it
One of the most spectacular dive sites in the Poor Knights, with a huge 8m wide arch in a promontory wall. Currents through the arch can be very strong so caution needs to be exercised here, especially as the arch is 40m deep. Wall is covered in colourful sponges and bryozoans, interspersed with yellow zoanthids, solitary hard corals, common and jewel anemones. The arch is noted for the large groups of Short-tailed Stingrays that gather in and around it. There are also large schools of Kingfish, Maomao, Butterfly Perch and Demoiselles. Perhaps you may also see a Giant Manta, as we did. Sea Temp 19c (Jan 2008)
