Had an amazing time out with Blair. He really knows his spots and put us all on to kings! Was an amazing day and easily the best dive I’ve had for the whole of 2017!
Max Schofield

Great boat for getting (quickly) to Great Barrier and the Mokohinaus. Last trip we came up from Wellington stayed locally and Blair really looked after us, including weights.

I have been on three charters with Blair, and will definitely be going on more! He put me onto my first of a bunch of species including Kingfish, Snapper, Trevally, Boarfish and more! No matter the conditions he had a spot to go dive and see awesome territory and fish life.

Esther Stuck

Ocean diversity is a fantastic spearfishing charter! I really enjoyed the couple of times Blair took us out, he is an awesome guide and really knows his stuff. Blair took us to some great spots, and knew when the fish was "on"! We came home with a great haul and even scored a crayfish on our first trip out! Would highly recommend this charter with the pleasure of having a friendly, knowledgeable skipper.

Blair runs a great charter, and knows the spots, times and tides to pick up great fish. Can't wait to get back out with Oceandiversity.

Recently we took a morning boating trip with OceanDIVEsity, departing Marsden Cove, out to the Hen and Chicken Islands off the coast of Bream Bay. We had a great morning. Only six people on board plus Blair and he took us to some really superb places to snorkel.
