Hello Mick, and welcome to the friendly Camera Labs forum!
To enjoy your stay here please have a look at the house-rules
I've tested the lens last year against the new 18-35/3.5-4.5G on my D800 and unfortunately forgot to write-up the results
I'm currently working on it. Expect my review to be published in the next 2 weeks.
But you can find a summary of my findings in my verdict for the 18-35 lens here
In short (quoting myself): "So if you don't need the aid of image stabilization which gives you a 2 stop advantage there's not much to recommend the 16-35/4.0 G VR over the 18-35/3.5-4.5G."
But if you have a little patience, you can read my full review of this lens soon...
