Start Google Chrome on Mac with command line switches

This works with macOS:

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --kiosk

It is probably even better to use the open command (in case the application is not located in the Application folder). E.g.: open -a "Google Chrome" --args --kiosk http://www.example.com

In AppleScript, paste the following text:

do shell script "/Applications/Google\\ Chrome.app/Contents/MacOS/Google\\ Chrome --kiosk"

Save it as an application and add it to your startup items.
