About this site
Long Cave, also known as Matt's Crack, is a cave dive at Aorangi Island off Matapouri on the Tutukaka Coast of Northland, New Zealand, part of the wider Poor Knights Islands coastal area. The island's volcanic rock has been carved into caves, crevices and swim-throughs, and this site is one of those cut formations along its shoreline. Divers working this stretch out of Matapouri and Tutukaka have reported Clown Doris, Cook's scorpionfish, eastern king wrasse, eastern pigfish, grey moray eels, New Zealand black angelfish, New Zealand demoiselle and yellowtail kingfish here.
