In her 2025 autobiography, A Different Kind of Power, Jacinda Ardern confirms what many around the world have long sensed: she is one of the most remarkable political leaders of our time. Few contemporary politicians have resonated so deeply and so widely—particularly on the left of the political spectrum—through a combination of empathy, moral clarity, and unmistakable sincerity.
What makes this memoir compelling is the leadership philosophy that quietly underpins them. From a leadership perspective, four themes stand out.
The first is a striking absence of ego. Ardern does not seem driven by a desire to be at the center of attention; rather, she is animated by a desire to make a difference. Throughout the book, she returns to the idea of usefulness, of being of service. She describes public office as an honour and a responsibility, not a platform for personal glory. Many leaders claim they serve, but in her case it feels credible. Her tone is reflective rather than self-congratulatory. Even when recounting moments of global praise, she quickly redirects attention to her team or to the communities affected. The consistent thread is a desire to contribute, not to dominate.
The second is to perceive her imposter syndrome as a strength. One of the most revealing passages concerns the moment she was asked to take over the leadership of the Labour Party. Her immediate internal reaction was not triumph but self-doubt: she began mentally listing all the reasons why she was not capable of the task. Yet she reframes this not as a weakness, but as a strength. Her self-doubt forced her to prepare meticulously, to seek advice, and to listen carefully. It also kept her humble. Rather than assuming she had all the answers, she cultivated an environment in which others’ expertise mattered. In a political culture often dominated by bravado, judgments and overconfidence, Ardern’s account is refreshing.
The third is her sensitivity. As a child, she experienced stomach aches from stress. Later in life, the pressures of leadership manifested physically; stress lodged itself in her body, causing real pain. The challenge, she writes, was to retain her sensitivity without being overwhelmed by it. She refused to harden herself emotionally, even when political survival might have demanded it. Instead, she embraced “engagement” as a guiding principle: there is always something you can do for someone.
One of her coping mechanisms is to mentally compartmentalise painful dilemmas. She places difficult questions in a ‘box’ at the back of her mind and refuses to look at them. A poignant example concerns the tension between her personal values and the Mormon faith in which she was raised. For years, she suppressed the internal conflict so thoroughly that she struggled to articulate her position even to herself. Ultimately, she chose to leave the church.
The fourth is the leader as a mother. Motherhood forms perhaps the most intimate and politically charged section of the memoir. Ardern deeply wanted to become a mother, but conception did not come easily. To shield her fertility treatments from media scrutiny, she would enter the clinic through a back door at night. In an extraordinary twist, she discovered she was pregnant shortly after becoming prime minister. She concealed her nausea and carried on. When she first stood in Parliament as prime minister, she recalls thinking only that she must not vomit. Later, she became the first sitting prime minister to bring her baby to the United Nations General Assembly. The symbolism was powerful, but the lived reality was complicated. Ardern writes candidly about feeling as though she sometimes “failed the exam” as a mother. She worried about attachment, about not being mentally and physically present enough, about the high standards she set for herself.
These reflections lead her to a broader argument: pregnancy and motherhood should never become weapons against women in leadership. Women should not have to choose between professional excellence and being a good mother or daughter. A supportive network should be the norm, not the exception.
After finishing A Different Kind of Power, what lingers is the image of a sympathetic and sincere woman who approached high office as a form of service. Ardern’s autobiography is quieter than a triumphant political memoir in the traditional sense. It is the story of a leader who never fully silenced her doubts, never fully hardened herself against pain, and never stopped believing that politics could be an act of care.
