Pacific Excellence in Action: Tongan Researcher Leading Clinical Innovation in Aotearoa
In a story that exemplifies the power of Pacific contribution to Aotearoa’s health sector, Tongan-born clinical researcher Melemafi Porter is coordinating a study that could reshape how vaccines are administered nationwide—while also inspiring a new generation of Pacific talent in science, research, and medicine.
From her early days growing up in Wellington, Melemafi’s love for science was sparked by unlikely heroes: cartoon characters like The Powerpuff Girls and Jimmy Neutron. But behind that youthful curiosity was a deeper purpose—one that has now matured into a determined commitment to improve health outcomes for Pacific communities.
From Curiosity to Clinical Impact
After earning her Bachelor of Biomedical Science and later a Master’s in Clinical Immunology, Melemafi fell in love with research. Her journey connected her with the Medical Research Institute of New Zealand (MRINZ), where she saw firsthand how health research could drive real change in underserved communities.
Now undertaking her PhD, Melemafi is the lead coordinator of the COVID-19 Needle Length Study, which investigates whether the standard needles used for vaccinations are effective for people of different body types—a question with real implications for vaccine effectiveness and health equity in New Zealand.
Early studies suggest that the standard needle size may not always reach the muscle in individuals with higher body mass, potentially reducing vaccine efficacy. The current trial is testing two different needle lengths to examine their impact on immune response and side effects—data that could inform future updates to national immunisation guidelines.
A Proud Daughter of Tonga
Melemafi’s Tongan heritage—from the villages of Faleloa and Lotofoa (Ha’apai) and Kanokupolu (Tongatapu)—is central to her identity and motivation. She credits her village, family, and wider community for fuelling her success and resilience. Her work is a living testament to the values of collective uplift, service, and contribution deeply rooted in Tongan and wider Pacific culture.
“I’ve always had the village backing me,” she says. “This work isn’t just mine—it belongs to everyone who supported me along the way.”
She also draws inspiration from trailblazers like Professor Dianne Sika-Paotonu, another Tongan woman making waves in immunology. “Growing up, I didn’t see many Pacific women in STEM. Seeing her journey has been a source of reassurance and motivation for me.”
Representation That Reflects Aotearoa
For Melemafi, increasing Pacific representation in medical research is more than just a goal—it’s a necessity. “We need our communities reflected in the data so that the solutions are relevant and equitable.”
She’s actively working to recruit more Pacific participants in the COVID-19 Needle Length Study to ensure Aotearoa’s diverse populations are included in research that will shape future public health decisions.
“Representation isn’t a buzzword—it’s about getting real answers for our people. If we’re not part of the trial, we won’t be part of the solution,” she explains.
A Positive Return on Investment
Melemafi’s journey is a powerful example of the positive return on investment that Pacific—and specifically Tongan—communities are delivering for Aotearoa. Through education, research, and service, individuals like her are improving not only their families’ futures but also contributing to national wellbeing and global health knowledge.
Whether it’s in the lab, the clinic, or the community, this new generation of Pacific professionals is proving that when we invest in Pacific success, we invest in a better future for everyone.
Advice for the Next Generation
For young Pacific students dreaming of a career in science or health, Melemafi has some heartfelt advice:
“Don’t be afraid of change. Seize the opportunity when it comes. I’m not the smartest person in the room, and I’ve often needed extra time to grasp things. But learning at your own pace is okay. There’s room for you here.”
