Harcourts International Announces Key Global Leadership Appointments, Championing Senior Female Talent

In a significant move that underscores its commitment to fostering internal talent and empowering female leadership, Harcourts International Ltd (HIL) has announced the promotion of two of its most accomplished senior women to global leadership positions.

Teagan Seccombe (pictured left), has been appointed as the new Head of Events and Partnerships for HIL, whilst Karmen Costigan (pictured right) takes on the role of Head of Property Management across the entire Harcourts International network.

These appointments highlight the strategic importance Harcourts places on recognising the exceptional talent already thriving within its ranks. Both women have established remarkable track records of success in their respective fields, driving innovation, commercial outcomes, and cultural alignment.

Teagan Seccombe formerly the Head of Events for Australia, steps into her expanded role to oversee all events and business partner relationships across New Zealand and Australia. With over a decade of experience across international markets, Seccombe is renowned for her ability to translate complex strategy into high-impact experiences.

Reflecting on her new role, Seccombe shared her vision for the future of Harcourts' events. "I am passionate about designing experiences that matter—those that elevate leadership, reinforce culture, and move organisations forward. My approach has always been collaborative and grounded in building strong relationships with our stakeholders and partners, and I am thrilled to bring this focus to our broader trans-Tasman network," she said.

Similarly, Karmen Costigan brings over two decades of robust industry experience to her new global role. Previously the Head of Property Management for Australia, Costigan has built a formidable reputation for driving high performance and growth.

"The property management landscape is evolving rapidly, and the businesses that succeed are those willing to innovate, invest in their people, and implement best practices," Costigan noted. "I am excited to take what we have built in Australia to the global stage and work alongside our international teams to continue raising the bar."

Mike Green, Managing Director of Harcourts International Ltd, praised both leaders for their outstanding contributions.

"Whilst we are always thrilled to welcome brilliant new talent into the Harcourts family, there is nothing quite as rewarding as watching our own people grow and step into global leadership roles. Promoting from within is a cornerstone of our culture; it ensures that the passion, institutional knowledge, and deep-seated values of our brand are carried forward as we continue to expand and innovate worldwide."
