Our Story

Welcome to XL Strategy, based in the vibrant city of Christchurch, New Zealand. Our journey began with a vision from our founder, Duncan, who noticed a critical gap in the business world: a significant lack of investment in leadership behaviours and the tools necessary for fostering effective leadership. This realisation sparked a question: How can we make a meaningful difference, one leader at a time, and thereby enhance our entire community? 

At XL Strategy, we are driven by a passion for uncovering and nurturing individual strengths. We believe that by developing better business leaders, we're not just improving workplaces—we're enhancing lives at home and across communities in New Zealand and Australia. Our approach is as dynamic as it is thoughtful. Like a chameleon, we listen attentively and adapt to the unique needs of each individual we work with.

We equip our clients across Australasia with a new set of tools—a toolbox for leadership that enables them to create positive, sustainable environments and cultures in their organisations. Our mission is to transform good leaders into great ones, and great organisations into exceptional ones. At XL Strategy, we're dedicated to Building Strong Leaders for Stronger Communities, both locally and across the broader Australasian region.
