Hidden Nurbs sub-service still visible in render

I have a nurbs sub-surface that is acting as a slicing object for another surface within the object. I don’t want this slicing surface to be visible in the render so I tell that sub-surface to be hidden.

However, it still renders. Is there any way to get around this?

Can you post (a part of) the scene?
