Thanks for the advice guys, I'm naturally paranoid about government departments losing or screwing up paperwork, especially living here as a "guest" on a Visa, so I would definitely take a high resolution colour photograph of my old license before handing it over or destroying it!
I did the same thing when I exchanged my NZ license for a UK one. I was rather miffed to find that I had to give up my NZ drivers license before being given a UK one - why it's not possible to keep both I don't understand. Whether its just the photo license card that I no longer have or whether my NZ license has actually been cancelled and will have to be re-exchanged from a UK one should I go back I don't know!
If they had lost my NZ license during the exchange or mucked up the entitlements I would have most likely been in a real predicament, as there was no other proof that I'm allowed to drive in the UK (no UK drivers test on record etc) and its unlikely that I could obtain a new copy of an NZ drivers license from the UK...
Does anyone know whether they're waiting on me to send back the old one before sending the new one when I've used the online change of address form ? The wording of it suggests that they will send the new one out as soon as the details of the change have been confirmed and processed, and that they want me to send the old one back, however it doesn't explicitly say whether they will dispatch the new one before receiving the old one...
I also have an NZ passport to renew before August (which will require me to send away by mail my only proof of being able to live and work in the UK!) and then have to renew my Visa next year which means sending my passport away again! Lots of opportunities for government department screw ups to happen or documents to be lost in the post...
