You haven't given us enough info about where the parameters are coming
from (i.e., how you're calling your script) or what you're doing with
them inside the loop.

Here is a complete sample script called check_spaces.zsh:

#!/bin/zsh
for file in "$@"
do
  /bin/echo $file
  /bin/echo "$file"
done
# --end--

If I call it thus:

    check_spaces.zsh *

I get two spaces for a file that has two consecutive spaces in its name. 
If I run it with bash, however, I get consolidated spaces in the output
of the first echo line, without the parameter quoted.

In short, I don't know why you're having problems :-)
