NORTHERN ARCH

Bluefish
NW end of Tawhiti Rahi, POOR KNIGHTS ISLANDS, NORTHLAND
Depth: 0-40m
One of the ultimate dives on its day. Schools of blue maomao, pink maomao and others move through the arch, sometimes accompanied by stingrays and kingfish. Look in the cracks below 30m for bluefish, toadstool gropers and yellow-banded perch and nudibranchs, sponges and every imaginable invertebrate on the walls both inside and outside the arch.
