      Strategic Leadership & Organisational Culture Expert, Authority on Navigating Complexity

      Core Intelligence Domain: Leadership
      Location: South Africa | Languages: English
      Representation: Represented globally by PSpeakers Global Intelligence

      Niven Postma is a globally recognised authority on organisational culture, leadership strategy, and the ethical navigation of office politics, equipping C-suite executives and senior leaders with the proprietary frameworks required to drive complex strategic execution. With an expansive executive background that spans the financial, regulatory, and non-profit sectors, Postma brings a unique, systems-level perspective to how power, influence, and culture intersect within high-performing organisations. She empowers leaders to shift their mindset regarding internal dynamics, transforming office politics from a perceived toxic barrier into a vital instrument for ethical influence and sustainable organisational growth.

      A Proven Record of Executive Leadership

      Postma’s strategic foresight is built on a foundation of significant senior leadership roles. She has served as the Head of Leadership and Culture for the Standard Bank Group, where she architected cultural transformation initiatives for one of Africa’s largest financial institutions. Additionally, she was the Head of the SARB Academy at the South African Reserve Bank, managing advanced executive education and strategic capability building. Her tenure as the CEO of the Businesswomen’s Association (BWA) of South Africa further solidified her reputation as a formidable advocate for inclusive leadership, diversity, and the structural advancement of women in the corporate sphere.

      Proprietary Insight: Ethical Office Politics

      As a leading intellectual in corporate behaviour, Niven Postma is best known for her groundbreaking and widely acclaimed book, If You Don’t Do Politics, Politics Will Do You: A Guide to Navigating Office Politics Ethically and Successfully. Her proprietary framework challenges the conventional wisdom that office politics is inherently destructive. Instead, she teaches global executives how to map stakeholder ecosystems, build relational capital, and wield informal networks to execute strategy effectively. Her insights help mitigate organisational friction, reduce talent attrition, and accelerate change management in highly matrixed corporate environments.

      Global Academic and Advisory Contributions

      Beyond her corporate and speaking engagements, Postma holds esteemed academic and advisory positions. She serves as an expert facilitator for leading global business schools, delivering cutting-edge programmes on leadership and complexity. Her advisory work extends to international boards and executive committees, where she provides strategic counsel on cultivating cultures of high trust, accountability, and commercial resilience.

      • “Niven was CEO of the Businesswomen's Association during my tenure as a member of the National Council. When Niven came to the organisation it was suffering from lack of brand awareness and stilted membership growth. Niven applied drive, energy and passion to the task of putting the BWA "on the map". Membership grew and the organisation gained recognition. Niven was a natural leader, who was willing to learn and grow. She accepted feedback and used her increasing knowledge to bring stability to the organisation. Niven made things happen - the Census became a landmark initiative, branch co-ordinators were given all the support necessary to be more effective and members enjoyed her easy style. Under her leadership the website became a sophisticated communication medium and the organisation prospered. Like all non-profit organisations balancing the finances was always a challenge but Niven apporached the task with honest integrity. She was a fearless leader that rode the storms with dignity and strength. I enjoyed working alongside her and admired her deep sense of commitment.Niven was CEO of the Businesswomen's Association during my tenure as a member of the National Council.

Her ability to manage a fluid and rapidly changing environment with scarce resources was a great benefit to our organisation.”
