Great to go and look at their shop and take photos with characters such as gollum and others in the lord of the rings and can purchase gifts. They also have a tour which we did not go on, but if we had more time we definitely would have gone on the tour
Sad to hear you didn't manage to get the time to go on our Window into Workshop tour.
Hopefully you can take advantage of the cheap flights Airnz offer to come down and do it sometime.
