DVLA won't be informed and it wont affect your driving record.
However the offence will stick effectively forever, and according to DriverAbroad.com
Some countries have a more stringent approach than others. I’ve heard a number of stories of New Zealand Zealand authorities employing debt collection agencies abroad to pursue fines for instance. I’ve also heard of some European countries ,especially in Scandinavia and Eastern Europe checking the licences of drivers in foreign registered cars crossing their borders for outstanding fines.
This could lead to a default listing in your home country which would effectaffect your credit profile.
Additionally, if you were driving a rental, they may charge you the fine directly.
