What you need to collect and send to Council (we will hand it to Nokia) is the list of winners including name, device and Nokia Developer account. The rest of the details should be available in their ND profile.
Anyway, one need to just register on developer.nokia.com, providing complete shipping address data. As Nokia have just moved to "one login" system, it may be little confusing - don't worry, even if You mess something during registration, You can modify address data later, just after logging in, and going to your profile settings.
Unrelated comment - be happy, that You're receiving devices now, not at CA times, when Nokia merged database (for "one login") just after every receiver registered on developer.nokia.com. As a result, one user from UK got "Papua/New Guinea" assignes as his shipping address, and another one found - in his profile - data of someone else, including mail address and phone number As it should be all fixed now, those are emotions, that current winners are gonna miss
