Katrina played Minnie Crozier on New Zealand's original long running soap, Shortland Street, from 1994-2001. She began at the young age of 13 and got her education in between filming. Minnie was a receptionist at the Shortland Street Hospital.
Katrina's Power Rangers Ninja Storm co-stars, Katrina Browne (Kapri) and Pau Magasiva (Shane/Red Ranger) were also on Shortland Street. Browne had a mid-term role in 2000-2001 and Magasiva had a guest-spot in 2001.
Katrina worked with cast member Emma Lahana when she had one year role between 2000-2001. They became good friends and would of course go on to work together again on Power Rangers DinoThunder.
