It takes weighty matters of colonial history and cultural identity and wraps them up in a cracker yarn about life and death, dark and light, deceit and discovery. A sincere, heartfelt attempt to enter into and convey a Maori story told through Maori eyes, this adaptation of a Witi Ihimaera novella is doubly commendable because it is written and directed by a film-maker who was born, and learned her craft, in Mexico.
Rotberg, who says she was inspired to come and live in New Zealand after seeing Whale Rider, read voraciously about Tuhoe and spent time in Te Urewera, where the film is set, during the development process.
Her respect for and knowledge of tikanga, which is evident in every frame, would put many pakeha New Zealanders to shame. And the payoff is a handsome and accomplished film whose calm exterior belies its powerful beating heart.
She's chosen an evocative and apt title (the Maori version, Tuakiri Huna, means something like "hidden identity") for an adaptation of Ihimaera's Medicine Woman, which appeared in the 2007 collection Ask the Posts of the House.
The original, which is far from the writer's best work, was nevertheless driven by a brilliant idea, the essence of which will not be divulged here.
