Meet the People
Our Team
A tight-knit, diverse team with decades of experience in primary and community care, delivering at scale using an emergent approach.
Ny Brunenberg
Interim Chief Executive Officer
Based in Wellington, Ny brings a diverse background across quality accreditation, primary care, PHO environments, service design, and digital health. As Interim Chief Executive of Collaborative Aotearoa, she is focused on strengthening connection across the sector, supporting practical innovation, and enabling primary and community care teams to deliver safe, high-quality, and culturally responsive care.
A first-generation Cambodian-Kiwi, Ny's understanding of resilience, wholeness, and wellbeing has been shaped by her family's experience of surviving the Khmer Rouge in Cambodia. This deeply informs her commitment to equity, inclusion, and care that recognises the whole person, whānau, and community.
With experience across general practice and PHOs, Ny brings a creative, people-centred approach to supporting model of care implementation, strengthening diversity, and improving quality access to care across Aotearoa.
