(Press release Auckland University) When a world-leading Oxford sleep scientist visited Sāmoa and Aotearoa as part of a
prestigious Hood Fellowship, Li’amanaia Dr Roannie Ng Shiu was already thinking
beyond sleep.
From the villages of Savaia and Leone in Sāmoa with international research
collaborations spanning Oxford, Auckland and Apia, Dr Ng Shiu is helping shape a new
Pacific-led approach to youth mental wellbeing
The University of Auckland academic and co-director of Te Poutoko Ora a Kiwa, the
Centre for Pacific and Global Health, is on the threshold of research looking to improve
the mental wellbeing of Pacific young people.
Ng Shiu is co-leading a groundbreaking project with University of Auckland
chronobiology scientist Dr Nicola Ludin, exploring how sleep and circadian rhythms
could help address anxiety, depression and other mental health challenges among
Pacific youth. The project has attracted international attention through collaboration
with Professor Russell Foster, one of the world’s foremost circadian neuroscientists
from the University of Oxford, whose recent visit to New Zealand and Sāmoa was
supported by a Hood Fellowship.
The research team is also set to feature prominently in an upcoming TVNZ documentary
on sleep and circadian rhythms, expected to screen later this year, bringing the
innovative work to a wider public audience.
Ng Shiu says the project grew naturally from previous research examining mental
health among adults in Sāmoa.
“Since then, that’s been the main thing,” she says. “It’s off the back of the mental health
baseline study we did for adults in Sāmoa and now moving towards young people.”
While the science behind circadian rhythms can seem complex, Ng Shiu sees its appeal
in its simplicity.
“What we liked is the fact that it’s a non-pharmacological intervention,” she says. “It’s
about improving mental health and addressing anxiety and depression without having
to go to pills.”
For Pacific communities, she believes that approach has particular significance.
“Everyone has to sleep. If we can get sleep right, it’s the same as eating well and
exercising. Sleeping well becomes a fundamental pillar for supporting the mental health
and wellbeing of our young people.”
The collaboration has brought together expertise from multiple disciplines and
countries. During Professor Foster’s visit, University of Auckland researchers travelled
to Sāmoa to meet academic and government leaders and discuss the role sleep could
play in improving youth wellbeing, literacy and educational outcomes.
Ng Shiu says the project is currently focused on preparing culturally relevant resources
for Sāmoan communities while seeking funding for future data collection.
Working alongside Professor Foster, the team is adapting existing educational resources
for Sāmoan populations and engaging directly with communities and decision-makers.
“We’ve spoken to community people and ministers, and they’re all really interested,”
she says.
One challenge has been reframing the conversation.
“People automatically think the project is about sleep disorders. We’ve moved the focus
away from sleep and instead we’re saying we want to improve mental wellbeing for
kids, and we’re going to do that through good sleeping habits.”
The project aligns strongly with Ng Shiu’s wider work as a Pacific public health
researcher, advocate and international leader. Alongside her University of Auckland
roles, she continues to contribute to major Pacific health initiatives as Executive
Director for the Pacific Academy of Sciences, including work connected to the influential
Lancet Commission and regional policy development.
She recently accepted an invitation to speak at an international conference in Palau,
building on previous Pacific research collaborations and highlighting the growing global
interest in Pacific-led approaches to wellbeing, sustainability and health.
Ng Shiu also sees connections between the emerging science of circadian rhythms and
traditional Pacific knowledge systems.
Working alongside Pacific health leaders, including Dr Epaggelia Efu in Sāmoa, she
believes the research reflects values and practices that have long existed within Pacific
communities.
“This fits 100 percent into some traditional knowledge and practices that we have,” she
says. “I think it’s more about reviving that more.”
As funding applications progress, Ng Shiu remains focused on building momentum and
growing interest in a project she hopes could eventually be rolled out beyond Sāmoa.
For now, the goal is clear: creating evidence-based, culturally grounded solutions that
help Pacific young people thrive.
“We’re just trying to get this right here,” she says. “Then we can roll it out everywhere
else.”
As a researcher, Ng Shiu is balancing multiple leadership roles, international
collaborations, community partnerships and a growing public profile, the project is
another example of the commitment to find innovative Pacific solutions to some of the
region’s most pressing health challenges. And the research could show that something
as fundamental as a good night’s sleep could help transform the wellbeing of a
generation.
