It has a QR skewer. The wheel does not buckle, and I will be checking the dropouts next. 

My guess would be that the dropouts are not your problem.

It’s either axle spacing or dishing, dishing doesn’t just go out, unless the wheel was not dished properly to being with and spoke length not correct (in this case drive side)

But for now I’m gonna guess axle spacing.

so I'm an idiot...

Are the gaps that imbalanced all the time?

If so, then it's a wheel dishing and the 'relocating' you're talking about is wheel flex. 29er MTB wheel flex a lot.

If the wheel is centred and then becomes imbalanced after use, then it's something else.

I think your 'relocating' terminology is the confusing factor here

OOOOK, so it looks the root cause has been found!😀 The locating nuts(?), circled in red, were switched around, offsetting the whole wheel to one side. This was discovered when stripping the whole axle, and re-assembling it. The wider of the two was placed on the brake side, which moved total wheel over to correct position. Re-aligned brake caliper and it's good to go! Thanks to all who gave advice and info, made us all think a bit!! Apologies for incorrect part names, but hopefully it was sort of clear explaining the problem.

Glad it's sorted. I had a brand new Aksium race, wheelset bought at an LBS and the dish was out on the rear.
