When going downhill on my haibike and particularly using the front brake I can feel some slack in the headstock (the steering bearings) looking down the side of headstock I cannot see any obvious nuts BUT in middle of handlebars is an Allen key socket ~ is it just a matter of tightening that??

Firstly, slacken the bolts that clamp the handlebar stem to the fork tube.
Next, lightly tighten the centre screw in the top cap/cover, make sure you don't over tighten the bearings.
Re-align the handlebars and forks to straight ahead position, tighten/torque the stem bolts.

There are several different types nowadays, an answer that fits all is not possible to my mind.
Check this link below to identify your model and/or make a clear photo for us all.
Headset adjustment is actually quite easy to do.....and many websites detail it better than I can!!
Most today need the clamp for the handlebar itself loosened to achieve the adjustment, my opinion only!!

Exactly as JPGiant has advised.
Here is a video explanation:
Using the front brake as a test of bearing play as described in the clip, isn't actually a very efficient or correct way of checking for free play, as it doesn't take into account the flex within a brake system.

The most effective way is to place the front wheel against a wall and then push forward to feel for flex.

Cheers all it's MILES better! It really only manifested itself when going down a steep rough concrete path (actually a footpath) and it's lovely now!

BTW the pressing bike against wall to test is a bit inconclusive best way I think it's to ride a fairly quick pace and put on front brake sharply.

Eddies suggestion is a good sound check and would do that first then use a test ride to find out.
