Made in New Zealand is a documentary about acclaimed New Zealand children and young adults writer Margaret Mahy. The 20 minute film takes a line from her award-winning novel The Changeover — "made in New Zealand, it said, Wisdom Laboratories, Paraparaumu" — and uses it to talk about the importance of New Zealand settings in Mahy's work, her international successes, and her life as a writer. Mahy is filmed at her home in Governors Bay, speaking to children in her famous rainbow wig, and out and about on Akaroa Peninsula.
