McMillan Bergman arrived in Kerikeri from the United Kingdom with her family in 1991. Her parents signed the entire family up to the theatre company, and she began singing in her primary school choir when she was 6 years old.
At 12, she was a semifinalist on the TV show McDonald's Young Entertainers singing Think of Me from Phantom.
Songs from the show came into her life again when she was a guest vocalist performing duets with the late Rob Guest during his tour of New Zealand in 2006.
She said the musical is close to her heart, so it was very exciting when, 20 years on, her dad spotted the advertisement for Phantom auditions in Whangārei - it was an irresistible opportunity.
"Performing for a live audience is an incredible experience. There are no re-takes or edits," she said.
With two young children, it's been a few years since McMillan Bergman's been able to make the time for such a big show, and she almost missed her chance because of family commitments.
After a talk with the Whangārei Theatre Company production team, she was eventually able to try out.
"I was over the moon. Musicals take us on a magical journey - the singing, acting, dancing and of course, the costumes."
McMillan Bergman lives near Kerikeri with husband Max and children Finn, 5, and Ella, 3. She said it takes a lot to balance her commitments to the show and to her family.
"I'm lucky to have such a very patient husband," she said
Performances will be held at 7.30pm on June 6, 8, 13, 15, 19 and 22, with a 2pm matinee on June 16.
