Also great eating is Terikihi, gurnard, Kahawai (sea trout), Mao Mao, shark (Lemon fish) and many reef fish such as parrot fish, leather jackets and john dory, if you dive crayfish (lobster) Scallops and mussels are not to hard to get and clams such as Pipi, Cockles, Tuatua are easy for the whole family to gatherHi Jamie
Looking at a picture on a friend's web site it looks as if Marty's right in the middle of Ascension island's Blue Marlin season. So the chances of getting a reply for the next couple of months is questionable. Sorry!
But just looking around it looks as if the main species from the rocks will be Snapper with boatwise - on the reefs - Snapper, Grouper and the species they get very excited about - Yellowtail Kingfish. Looking through these sites might well be accessing.
http://www.fishnz.co.nz/. A reasonable Portal site.
http://www.fishing.net.nz/index.cfm. An excellent information site, complete with forums.
http://www.beachfishingnz.com/?CFID=16637107&CFTOKEN=36434364. Albeit slightly further south - Bay of Plenty area - this chap guides rock and kayak fishing trip. Well worth scanning through though for tips.
http://www.wildbill.co.nz/. A boat based in Bay of Islands which, during their winter months, our summer, organises reef trips for individuals targeting Snapper, Grouper and Kingfish (Yellowtail).
Hope, as a starting point, that's of some help.
If you meant "kerikeri" I have a sister living there.Ive done a bit around the north island...mainly from the beech...(loose turm) had fantastic times... their is nothing like a fresh meal straight from the sea onto a bbq... went out for a couple of trips on a boat out of the bay of islands... it was great......going back to the jaffas next month.. and hoping to get up to kiri-kiri in march... and if i dont get any fishing in... i WILL hang myself from the longest Yard-Arm.....:happy:
