Mainly just diving for crayfish - I took 7 over a couple of dives. All bucks interestingly.
No spectacular fish, just reef stuff. Shot two large blue moki though, and saw a few decent red moki (which I don't tend to shoot, as I was told they mate for life, and are a bit scarce). Also took a nice blue cod, plus butterfish and a few paua.
I love the Wairarapa coast, it's a stark, harsh piece of coastline, that's often quite windswept. Weather conditions and the fact you need to drive over gravel road for a decent part of the journey means that it's not overfished, and if you can get into the water you're going to pick up a good feed of crayfish minimum.
I tend to walk around north past the main point; although that takes you right near a large seal colony that's currently resident if you have nightmares about white pointers... White rock itself, which has a very very basic campsite (basically some clear ground near the sea with a longdrop toilet) is also good diving if conditions allow.
Well worth a visit, but choose your time carefully in terms of weather conditions.
