Youth activism has been a defining feature of Aotearoa's recent political landscape. Amidst these unsettling political times haunted by climate change, colonisation, ongoing inequality and the upheaval of the pandemic, the political actions of young New Zealanders are a source of inspiration, challenge and renewal. Fierce Hope opens the doors on six influential activist groups: ActionStation, Generation Zero (Auckland), InsideOUT, JustSpeak, Protect Ihumatao, and Thursdays in Black (Auckland). Participants from these groups, through interviews, explain vividly what future they want for our country and how we can get there. They address an array of urgent issues, from indigenous rights to the justice system and imprisonment; from climate change to gender and sexual inequalities. In their voices we hear hope, anger, despair and anxiety - emotions which inform and galvanise activism. A connecting thread is how people within these different groups collectively negotiate their visions and strategies to achieve change. Their stories provide important insights into the immense demands of activism and help inform radical new ways of living and being together in Aotearoa New Zealand.
