Aaah, it's so unnerving being in a new place!
How old is your new kitty? Any previous homes? Some cats, are by mature naturally nervous. As Desley says the more she hears your voice (obviously being calm and soothing)the more she associates you with safety. It takes time with any animal, but I'm sure she'll be fine.
Another valid point is to try and get her a room with a few less places she can get herself "wedged" and possibly hurt herself. Under a chair is fine, but in the cooker drawer could get a bit upsetting!
