New Zealand needs to decide what kind of country it wants to become before deciding what it needs to build, according to Infrastructure New Zealand, as more than 1,000 industry leaders gather in Ōtautahi Christchurch for Building Nations 2026.
Infrastructure New Zealand is calling for Aotearoa to establish a clear national economic ambition capable of guiding investment in roads, rail, energy, ports, housing and other critical infrastructure over the next 30 to 50 years.
Chief executive Nick Leggett says New Zealand has plenty of ambition but has struggled to reach enduring agreement about its economic destination and the infrastructure required to get there.
The concern is that major projects are too often debated individually without first establishing the economic, population and social outcomes they are supposed to support.
That approach can leave governments arguing over whether to build a road, railway, port expansion or electricity transmission project before reaching agreement on the future demand that infrastructure is intended to meet.
Infrastructure should follow ambition
Infrastructure New Zealand wants that process effectively turned around.
The organisation argues energy transmission investment should follow the country’s energy ambitions, port development should follow its export ambitions, and housing should be planned around employment and population growth.
That requires New Zealand to confront some significant long-term questions.
How large will the population become?
Where will people live?
Which industries will drive economic growth?
What will Aotearoa export?
How much electricity will the country require as transport and industry become increasingly electrified?
And what infrastructure will communities need to support that growth?
Answering those questions first could provide a clearer foundation for deciding which projects deserve billions of dollars of public and private investment.
Three-year politics meets 50-year infrastructure
One of the biggest challenges is the mismatch between New Zealand’s three-year political cycle and infrastructure that can take decades to plan, consent, finance and construct.
A change of government can bring a change of priorities.
Projects can be cancelled, redesigned or delayed. Strategies can be rewritten, funding redirected and debates that appeared settled reopened.
That uncertainty can increase costs and make it harder for the construction sector, councils and investors to plan ahead.
It can also mean New Zealand spends significant amounts developing projects that never proceed.
Infrastructure New Zealand’s challenge is therefore not simply about building more.
It is about creating enough political and institutional stability that long-term national objectives can continue even when governments change.
Building Nations puts productivity on the table
Those issues will be front and centre at Building Nations 2026, bringing together more than 1,000 infrastructure leaders in Ōtautahi.
The gathering will examine how New Zealand can lift productivity, speed up project delivery, attract investment and make better use of infrastructure already in place.
Productivity is particularly important because infrastructure affects almost every part of the economy.
Congested transport networks cost businesses time and money.
Insufficient electricity generation and transmission can constrain industrial development.
Poor water infrastructure can limit housing growth.
Housing shortages can make it harder for workers to live near employment.
Port and freight capacity can influence the competitiveness of exporters.
Infrastructure therefore becomes both a consequence of economic growth and one of the foundations required to generate it.
Who pays for the vision?
A 30-to-50-year infrastructure strategy also brings an unavoidable question — how will New Zealand pay for it?
The scale of investment required across transport, electricity, water, housing and resilience is substantial, while central and local governments face competing demands for health, education and other public services.
Infrastructure New Zealand wants greater attention placed on unlocking investment alongside improving the way projects are delivered.
That could involve a combination of central government, councils and private capital, depending on the infrastructure involved.
But investors require certainty.
Constantly changing priorities can make long-term investment more difficult and expensive, reinforcing the case for a national direction capable of surviving elections.
Māori must have a place in a national ambition
Any attempt to establish a decades-long economic and infrastructure vision also carries significant implications for Māori, iwi and hapū.
Infrastructure projects can affect whenua, wai, wāhi tapu, housing, employment and economic development across generations.
At the same time, iwi organisations are increasingly significant investors and commercial partners with interests spanning property, energy, tourism, primary industries and infrastructure.
A national economic ambition therefore raises questions about how Māori aspirations, Te Tiriti relationships, regional development and intergenerational thinking are incorporated from the beginning rather than considered after major decisions have already been made.
For many Māori communities, thinking beyond one generation is already embedded in concepts of whakapapa and responsibility to mokopuna.
A 50-year infrastructure strategy would need to consider not only what produces economic returns today, but what kind of communities and environment future generations will inherit.
Regions need certainty too
The debate is equally important outside the major cities.
Regional communities need transport, digital connectivity, electricity, water and housing infrastructure capable of supporting new businesses and employment.
Without those foundations, governments can talk about regional economic development without providing the physical systems needed to make it possible.
Infrastructure New Zealand’s argument suggests those investments should follow a clearer understanding of which industries and regions the country expects to drive future growth.
That could give businesses, iwi, councils and communities greater confidence to make their own long-term investments.
Can Aotearoa agree on where it is going?
The challenge is that creating a national ambition requires political agreement on some difficult questions.
Parties may have fundamentally different views about population growth, taxation, climate policy, transport, energy and the appropriate role of government.
Infrastructure New Zealand is not arguing those political differences will disappear.
The bigger question is whether New Zealand can establish enough common ground around long-term national objectives that every election does not require the country to start again.
The stakes are substantial.
Infrastructure being planned today could still be operating in the 2070s and beyond.
The roads, railways, electricity networks, ports and communities created over the coming decades will shape where people live, where businesses invest and what opportunities are available to tamariki and mokopuna.
That makes the central question emerging from Building Nations bigger than any single motorway, railway or power line.
Before Aotearoa decides what it is going to build, it needs to decide where it is going — and whether today’s political system is capable of sticking with that destination long enough to get there.
