In 2020 arborist Zane Wedding (Ngāti Kuri, Ngāti Pikiao) a Mangere-born champion tree climber and senior lecturer at Manakau Institute of Technology undertook a 60-day protest to save a grove of ancient trees on public land in Avondale. He was arrested and during jail time was inspired to follow a path of activism guided by the wairua of his tūpuna. Short documentary Tū Tonu focuses on Wedding's life story, how he discovered his connection to rākau (trees) at his lowest point, and how this passion led him to sacrifice personal goals and instead fight for indigenous and ecological causes. Wedding also reflects on the painful side of choosing his life of activism.
