Ari Boyland is the newest former Tribe member to join Power Rangers. He is the Blue one. You can see him here. Not that great of quality, but still great to see him.
Per IMDB, there filmed in Auckland, New Zealand. I'm sure like the rest of us they have bills to pay and a paying job is a paying job. Many have worked on this show and have then moved on to other shows. Like Antonia Prebble has moved on to doing "Outrageous Fortune" http://www.imdb.com/title/tt0461097/ and Dwayne Cameron, Beth Allen and Fleur Saville moved on to "Shortland Street" http://www.imdb.com/title/tt0098911/, but I do know what your saying. But not all the New Zealand shows are shown all over like the power rangers are, so we do not get to see all the shows there on.
Oh totally, i wasnt trying to be insulting or anything. I just think its odd that many of them just end up being a power ranger. Still, acting is acting, and hopefully after Aris stint on this hell move onwards and upwards onto better things like the others.
I understand... I did not think you were being insulting. I apologize if I came back on you too strong. I know all of us wish all the cast members of The Tribe the best of luck.
