The film reunites actors Temuera Morrison and Cliff Curtis, both of whom starred in the iconic New Zealand film "Once Were Warriors."

"Ka Whawhai Tonu - Struggle Without End" is one of the first major films to use predominantly te reo Maori, highlighting significant efforts to preserve and promote the language within the context of a historical drama.

The filmmakers aimed for high historical fidelity, constructing a 1:1 scale fortified village using GPS technology to ensure accuracy in depicting the battlefield. They consulted with descendants of the original warriors to ensure the portrayal was authentic and respectful.

The movie premiered in Hamilton, Aotearoa New Zealand, a location deeply connected to the historical events it depicts. It was released nationwide during the Matariki holiday weekend, a time of cultural significance for Maori.

In addition to well-known actors like Cliff Curtis and Temuera Morrison, the film introduces newcomers Paku Fernandez and Hinerangi Harawira-Nicholas in lead roles. Their performances have been praised for bringing fresh energy and authenticity to the film.
