Moving files to NAS Changes Created Date

New to this....I've searched for ages and can't find anything on it! When I move files using Hazel, it all works great, when I move them to my NAS it seems to reset the created date of images/videos to today. It doesn't do this in other locations, just the NAS.
Any helpful theories as to what I can do to work around this? I'm trying to sort into folders and rename based on date, and I'd like to keep the capture date accurate....
