When I do a git status I get a list of files prefixed with new file: . How can I get only this list? I want to process this files in a simple loop in a little shell script.

The commands below no longer give the expected results, I may originally also have made some mistakes. Please double-check your output and the options you are using. Nevertheless: The basic tenet of using diff-filter should still hold true.
Don't use grep to parse git output. Git almost certainly has the things you are looking for built-in (except if you are going for really advanced stuff).
You can use git diff to show the changes. --name-only shows only the filenames. --diff-filter=A lists only the added files.
If you want to see new files you have already added to the index use --cached, otherwise omit it. To see both diff to HEAD.
The commands look like this:
git diff --name-only --diff-filter=A --cached # All new files in the index
git diff --name-only --diff-filter=A # All files that are not staged
git diff --name-only --diff-filter=A HEAD # All new files not yet committed
