This is the only known address for contacting the cast members of ninja storm. It can be used for all the actors of that show. I believe they will forward the letters you send to the actor.
I advise that you check with your post office to ensure that your letters have sufficient postage to reach New Zealand. Also include a self address stamped envlope or ask your local post office of what you should include so the actior can return your message. Remember these things take time. So give them a bit to respond.
Not guarenteed for Ninja storm has wrapped up its filming.
