University of Auckland Research Sheds Light on Language Support Shortfalls in Surgical Care
A recent study led by University of Auckland medical student Samantha Turnwald has brought attention to significant shortcomings in the provision of professional interpreters for Asian patients undergoing surgical procedures in New Zealand. Conducted as part of an ethics summer studentship and published in the New Zealand Medical Journal, the research examined interpreter utilisation during surgical consent processes at Waikato Hospital in 2023. It focused specifically on patients identifying with Level 1 Asian ethnicities who had limited English proficiency.
The analysis revealed that even when documentation clearly indicated language limitations, a substantial proportion of these patients proceeded through consent discussions without the support of a qualified interpreter. This gap raises important questions about patient understanding, informed consent validity, and broader equity in healthcare delivery across the country.
Background on Language Barriers in New Zealand Healthcare
New Zealand's population has become increasingly diverse over recent decades, with Asian communities representing one of the fastest-growing demographic groups. Many individuals within these communities arrive with varying levels of English proficiency, particularly older adults or recent migrants. In medical settings, effective communication is essential for accurate diagnosis, treatment planning, and obtaining genuine informed consent.
Professional interpreters play a critical role in bridging these gaps. Unlike family members or ad-hoc translators, qualified interpreters are trained to convey medical terminology accurately, maintain confidentiality, and remain neutral during sensitive discussions. The Health and Disability Commissioner Code of Rights emphasises the right to effective communication, yet implementation in practice can vary widely between institutions.
Waikato Hospital, serving a large regional population in the Waikato area, provided the setting for this retrospective review. The study reviewed records of Asian patients scheduled for surgical interventions, cross-referencing ethnicity data, English proficiency notes, and interpreter booking logs.
Key Findings from the University of Auckland Analysis
The research identified clear patterns of underutilisation. Approximately one in five Asian patients with documented limited English proficiency did not receive a professional interpreter prior to their surgical consent process. In several cases, consent forms were signed without any recorded language support, despite explicit notations about communication challenges.
Researchers noted that reliance on family members or staff with basic language skills occurred in some instances, practices that fall short of best standards for medical interpreting. These approaches can lead to misunderstandings about risks, benefits, and post-operative care instructions.
The study also highlighted variations by language group and procedure type, though overall trends pointed to systemic rather than isolated issues. Gaps were particularly evident in elective surgeries where advance planning for interpreter services should have been feasible.
Implications for Medical Education and Training at New Zealand Universities
As a project originating from the University of Auckland's Faculty of Medical and Health Sciences, the findings carry direct relevance for how future doctors are prepared. Medical curricula increasingly incorporate cultural competency and communication skills modules, yet the study suggests room for greater emphasis on interpreter protocols and recognition of limited English proficiency indicators.
University of Auckland students and faculty involved in the project gained hands-on experience in health services research, contributing to the growing body of evidence on equity issues. Such student-led initiatives align with broader goals of fostering research capability among emerging healthcare professionals.
Similar studies could be encouraged at other institutions such as the University of Otago or Auckland University of Technology to build a national picture of interpreter access across surgical and other clinical contexts.
Stakeholder Perspectives on Interpreter Services
Healthcare providers at Waikato Hospital and similar facilities face practical challenges including interpreter availability, booking lead times, and cost considerations. Professional services are often contracted through external agencies, which can introduce delays in time-sensitive environments.
Patient advocates and community organisations representing Asian populations have long called for improved access, noting that language barriers compound other access issues such as transportation and cultural familiarity with the system.
Administrators in district health boards and now Te Whatu Ora emphasise ongoing efforts to strengthen interpreter frameworks, yet the University of Auckland study provides fresh data underscoring the need for targeted improvements in surgical pathways.
Equity and Informed Consent Considerations
Informed consent is a cornerstone of ethical medical practice. When patients cannot fully comprehend the information presented, the validity of that consent comes into question. The research raises awareness of potential legal and ethical risks for both clinicians and institutions.
Equity in healthcare means ensuring that language does not become a barrier to safe, high-quality care. Asian patients, like other groups with limited English proficiency, deserve the same level of understanding as English-speaking counterparts regarding their procedures.
The study authors recommend systematic improvements such as routine screening for language needs at referral, proactive interpreter booking, and training for staff on when and how to engage professional services.
Broader Context of Asian Health Research in New Zealand
This project contributes to a growing body of work examining Asian and ethnic minority health experiences in Aotearoa. Previous scoping reviews have identified barriers including structural issues, cultural factors, and trust deficits within the health system.
University-led research plays a vital role in documenting these challenges and proposing evidence-based solutions. The involvement of medical students demonstrates how higher education institutions can integrate real-world equity questions into training programmes.
Recommendations and Future Directions
Based on the findings, the study calls for enhanced protocols at Waikato Hospital and potentially wider adoption across New Zealand surgical services. Suggestions include electronic flagging of language needs in patient records and dedicated interpreter coordination roles within surgical teams.
Longer-term, increased investment in interpreter workforce development, particularly for Asian languages, could address supply constraints. Partnerships between universities, health providers, and community groups may accelerate progress.
Further research could explore patient outcomes linked to interpreter use, satisfaction levels, and cost-effectiveness of different service models.
Impact on Higher Education and Research Capacity in New Zealand
Projects like this strengthen the research profile of the University of Auckland and contribute to its reputation for addressing pressing societal issues through academic inquiry. They also provide valuable experience for students considering careers in clinical research, public health, or health policy.
Funding bodies such as the Health Research Council of New Zealand support such student initiatives, recognising their role in building the next generation of researchers focused on equitable healthcare.
As New Zealand universities navigate post-pandemic recovery and evolving student demographics, studies highlighting real-world applications of medical training underscore the value of higher education in driving positive change.

Looking Ahead: Building More Inclusive Healthcare Systems
The University of Auckland study serves as a timely reminder that language access remains an area requiring sustained attention. While progress has been made in recognising diversity, implementation gaps persist in critical moments such as surgical consent.
By bringing these issues to light through rigorous analysis, the research supports ongoing dialogue among educators, clinicians, policymakers, and communities. Continued collaboration across sectors will be essential to ensuring all patients, regardless of language background, receive the support needed for safe and informed care.
