Great Barrier Island is a haven for casual divers and snorkellers and offers some of the most varied scuba-diving in New Zealand. Visibility is usually excellent and the abundant sea life offers rewarding dives in both shallow and deeper waters. At most times of the year crayfish and shellfish can be found around the coastline. The east coast is probably the best for crays but remember to only take the allowed limit otherwise you'll spoil it for everyone else as well as upset the local fishermen.
Diving is varied and exciting with magnificent underwater volcanic terrain, lush seaweed forests creating marine gardens with abundant fish life. Because of its amazing underwater topography with sheltered coves and bays, diving Great Barrier is safe for divers of all levels.
There are two famous shipwrecks which offer easy access by boat, and safe diving - the 100 year old Wairarapa, and the Wiltshire which sank in 1922. The latter is a spectacular wreck dive and can be penetrated under the guidance of a local underwater instructor or divemaster.
There are several great fishing spots in and around the island whether it be surfcasting from the coast, or relaxing on a boat. Surfcasting from the east coast beaches can bring good results and rockfishing from both coasts is possible. The best fishing is to be had in the early morning or twilight and always after a good blow and when the tide is running.
Wharf fishing with bait fish with the children is a fun activity but don't expect to catch any whoppers. These can be had by going big game fishing on the east coast. If you're not familiar with the terrain or new to fishing, then enlist one of the local fishing experts. Charter trips are reasonably cheap and you'll get to go to all of the best spots.
There are a variety of operators to choose from and Hooked on Barrier in Claris sells and hires fishing and dive gear etc. Bait is also available from Mulberry Grove, Claris and Port FitzRoy. Bookings are essential BEFORE arriving on the island to avoid disappointment.
