Instead of newgrp, use sg to run specific commands with the new group:

sg MY_NEW_GROUP -c "your_command_here"

Or start a new shell with the group:

sg MY_NEW_GROUP -c "$SHELL"

or

exec newgrp MY_NEW_GROUP

This replaces the current shell process. Works in M-x shell but will 
exit the shell when done.
