Aotearoa is entering a period of profound demographic change, with falling birth rates, rising living costs, workforce shortages and increasing migration creating challenges that could reshape the country’s social and economic future.
According to leading Māori demographer Professor Tahu Kukutai, the next decade will require careful planning and long-term thinking as New Zealand confronts population trends that are already beginning to alter communities, workplaces and whānau life across the country.
Speaking on a panel examining the future of population in Aotearoa, Professor Kukutai highlighted the growing pressures facing families and warned that demographic shifts now underway will have consequences extending far beyond simple population statistics.
A Nation Growing Older
One of the most significant trends facing New Zealand is population ageing.
Like many developed nations, Aotearoa is seeing people live longer while fewer children are being born. This shift means a growing proportion of the population will be older, placing increasing demands on healthcare, aged care services and government support systems.
At the same time, the number of working-age people available to support these systems is growing more slowly than in previous generations.
For Māori, however, the picture is more complex.
While the Māori population remains younger than the national average, Māori communities are also experiencing demographic transitions that will influence future education, housing, employment and health planning.
Professor Kukutai says understanding these trends is critical because today’s policy decisions will shape outcomes for generations to come.
The Cost of Raising a Family
Rising living costs are increasingly influencing how New Zealanders think about having children.
The costs associated with housing, childcare, education and everyday living continue to rise, creating new pressures for families already balancing work and financial commitments.
Many younger adults are delaying starting families or choosing to have fewer children than previous generations.
For some, concerns about housing affordability, job security and economic uncertainty are making long-term family planning more difficult.
These decisions are contributing to declining fertility rates across much of the country, with New Zealand joining a growing list of nations experiencing lower birth rates.
The implications extend beyond individual households.
Lower birth rates can affect school rolls, workforce growth, economic productivity and the sustainability of public services over time.
For Māori communities, where whānau structures and intergenerational relationships play a central role in social wellbeing, these shifts may also have important cultural implications.
Employment Uncertainty and Regional Impacts
Professor Kukutai also points to growing concerns about employment insecurity and economic restructuring.
Across several sectors, including manufacturing, energy, forestry and parts of the public service, workers have faced significant uncertainty in recent years.
Job losses and reduced economic opportunities can trigger population movement, particularly from regional areas where employment options may already be limited.
When people leave communities in search of work elsewhere, the effects ripple through local economies, schools, sports clubs and community organisations.
For Māori communities, which often have deep whakapapa connections to particular regions, population loss can weaken cultural, social and economic resilience.
The challenge for policymakers will be creating sustainable economic opportunities that allow people to remain connected to their communities while still accessing meaningful employment.
The Australian Pull Factor
One of the most visible demographic trends continues to be the movement of New Zealanders across the Tasman.
Australia’s stronger wages, larger labour market and broader employment opportunities have long attracted New Zealand workers, particularly younger adults seeking career advancement and financial stability.
Recent economic pressures have intensified that trend, with many skilled workers choosing to relocate.
Professor Kukutai says the loss of young workers has implications beyond labour shortages.
Migration affects the composition of communities, reduces the pool of future leaders and influences the country’s economic capacity over time.
The departure of skilled workers can also place pressure on sectors already experiencing shortages, including healthcare, construction, education and technology.
For Māori communities, migration raises additional questions about maintaining cultural connections, language revitalisation and relationships with iwi and hapū when increasing numbers of whānau live overseas.
As one of New Zealand’s foremost experts in Māori data sovereignty, Professor Kukutai has consistently argued that understanding demographic change requires better use of data and stronger Māori participation in decision-making.
Accurate population information plays a critical role in planning for housing, healthcare, education, infrastructure and social services.
However, she has also emphasised that Māori communities must have greater control over how their data is collected, interpreted and used.
Data sovereignty has become an increasingly important issue as governments and institutions seek to respond to complex social challenges while ensuring Indigenous rights and perspectives are respected.
The demographic changes facing Aotearoa are unlikely to be resolved quickly.
An ageing population, lower fertility rates, rising living costs and continued migration are trends that will shape the country’s future for decades.
Professor Kukutai argues that responding effectively will require more than short-term political solutions.
Instead, policymakers will need to think across generations, balancing economic growth with social wellbeing while ensuring communities remain resilient in the face of change.
For Māori, the challenge is not only adapting to demographic shifts but ensuring that responses are grounded in kaupapa Māori values, support whānau wellbeing and strengthen tino rangatiratanga.
As New Zealand navigates an increasingly uncertain future, the demographic choices made today may prove just as important as any economic or political decision.
Because ultimately, population is not just about numbers—it is about people, whānau, communities and the future shape of Aotearoa itself.
