Unveiling the Complex Path to Ending Domestic Violence: Lessons from New Zealand
"A deep dive into New Zealand's journey to tackle intimate partner violence (IPV) and what the world can learn from its successes and stumbles."
Intimate partner violence (IPV) is a global issue, demanding sustainable and integrated responses. New Zealand has long been a leader in addressing IPV, establishing a national health system framework within hospitals and community settings. Yet, extending these resources and engagement to primary health care remains a challenge. This article examines the factors influencing a sustainable IPV response within New Zealand's primary health care system, offering insights for other nations striving to create effective interventions.
Viewing the health system's response to IPV through the lens of complexity theory allows for a new understanding. This theory re-conceptualizes the IPV response as a complex adaptive system, and by analyzing key policy documents, strategies, and guidelines, this approach highlights how different agents (individuals and organizations) interact and influence the system's evolution. By chronologically threading these documents, the emergence of discourse influencing IPV responsiveness is mapped out.
This analysis reveals a complexity-informed implementation narrative of New Zealand's health system response to IPV over the past two decades, highlighting the crucial role (and challenges) of primary health care participation. The study demonstrates how competing discourses have contributed to system gaps and unintended consequences. These findings have implications for creating a sustainable IPV response in primary health care and emphasize the importance of addressing system interactions to achieve a comprehensive, nationwide approach.
The 'Gardyne' Protocol: A Promising Start

In 1995, New Zealand took its first steps in addressing IPV with the development of the 'Gardyne' protocol. This initiative, led by an Auckland-based research team, aimed to equip general practitioners (GPs) with the tools and training needed to identify and intervene in cases of IPV. The project recognized GPs as crucial frontline providers who could prevent escalation and mitigate the health effects of violence.
- Key takeaway: The 'Gardyne' protocol marked an initial effort to integrate IPV responsiveness into primary health care but faced challenges in achieving widespread adoption.
Key Lessons and Future Directions
New Zealand's journey to address IPV in primary health care has been marked by both progress and setbacks. The use of complexity theory provides a valuable framework for understanding the challenges and opportunities in this area.
This analysis highlights several critical system interactions that need attention: IPV must be consistently recognized as a key determinant of ill-health, policy directives are needed to ensure primary health care professionals respond to IPV, and active engagement with primary health care professionals is essential to promote IPV responsiveness. By addressing these interactions, New Zealand can further strengthen its health system's response to family violence.
New Zealand holds a leading international role in responding to family violence in healthcare. Given the complexity of developing and implementing sustainable health care responses to IPV, this paper contributes valuable insights for the international health care community involved in responding to IPV.
