What exactly is wrong with their placement?
What have you entered in \newgeometry{...}?
E.g., when you just increase the paper width, 
geometry may not feel a need to increase any 
other horizontal dimension, or it may increase 
a dimension that doesn't have a visible effect
(in your case), such as outer \marginparwidth. 
I.e., you may have to increase \textwidth 
explicitly.
