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!
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.
As a beginner at spearfishing I took my first ever boat trip out with blair an was a epic day.. Blair has great knowledge on selecting spots an also helping with tips and hunting techniques. A very comfortable boat even with a full charter.. Blair runs a awesome friendly trip an do recommend to spearos of any experience always a memorable day.
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.
