How is Infrastructure Development Determining Papua New Guinea’s Economic Future?
Building for Tomorrow
For Papua New Guinea, infrastructure is closely tied to the question of what kind of economy the country can build over the next decade.
The country has significant natural resources and a young population, yet economic opportunity remains uneven. Many communities are separated from major markets and services by difficult terrain, limited roads, unreliable electricity and inadequate connectivity. For businesses, those gaps can translate into higher costs, longer journeys and fewer opportunities to expand.
That is why infrastructure development in Papua New Guinea is about much more than building roads or upgrading power networks. It is about making it easier for people, businesses and communities to participate in the economy.
The need is becoming more urgent as PNG looks beyond its traditional dependence on mining, oil and gas.
Why is Infrastructure Important to Papua New Guinea’s Economy?
Infrastructure provides the basic connections an economy needs to function.
A farmer needs a reliable road to get produce to market. A manufacturer needs dependable electricity. A small business needs telecommunications and financial services to reach customers. A community needs transport links to access schools, hospitals and employment.
Papua New Guinea still faces major gaps in each of these areas. The World Bank says inadequate infrastructure is one of the constraints holding back productivity and job creation, particularly outside the country’s main urban centres. Better roads, electricity and digital connectivity are needed to support investment beyond Port Moresby and Lae.
The challenge is particularly important because around 85% of PNG’s population lives in rural areas, according to the World Bank.
How Can Better Roads and Transport Support Economic Growth?
Transport infrastructure can change the economics of doing business.
Transport of agricultural, construction, and other goods becomes more costly when infrastructure is in bad shape or transportation links are not reliable. Remote providers can have difficulties providing their products in substantial markets although their goods could be sold commercially.
Improving roads and bridges can shorten those distances in practical terms.
The Asian Development Bank is putting significant resources into this area. Its current work includes a $1 billion highway rehabilitation program, a $265.4 million project focused on district roads and bridges in the Highlands, and preparations for future investments covering 96 subnational roads.
Air connectivity matters as well. PNG’s geography makes aviation particularly important for communities that are difficult to reach by road. ADB is supporting the rehabilitation of five airports and upgrades to rural airstrips.
What Role Does Energy Infrastructure Play?
Reliable electricity is one of the less visible foundations of economic growth, but its absence is felt quickly.
A business cannot operate efficiently if power is unreliable. Hospitals, schools, telecommunications networks and households face the same problem.
ADB says only about 20% of people in PNG currently have access to electricity. Its sustainable energy program aims to raise access to 30% by 2030 while reducing the duration of power interruptions.
Expanding energy access could have consequences well beyond households. Reliable power can make it easier for businesses to invest, support cold storage and food processing, improve digital services and encourage industries outside the extractive sector.
PNG also has substantial natural energy resources, including hydropower, natural gas and solar. The long-term challenge is turning that potential into dependable and affordable energy for the wider economy.
Can Infrastructure Help PNG Create More Jobs?
Infrastructure alone does not guarantee employment, but it can make other parts of the economy more productive.
This is highly relevant for Papua New Guinea where economic growth has not resulted in an equivalent growth in formal sector jobs. The World Bank stated that the PNG economy expanded by 5.6% in 2025 but that formal employment ratio per capita has fallen due to a large number of new workers entering subsistence agriculture and low productivity informal economy.
Better infrastructure can help change that equation by connecting workers and businesses with markets.
Agriculture is a major opportunity. The World Bank estimates that strengthening agricultural value chains could generate around 330,000 additional formal jobs over the next decade. Better transport and market access will be essential if farmers and agribusinesses are to capture more of that opportunity.
How is Digital Infrastructure Changing Papua New Guinea?
Economic infrastructure is no longer limited to roads, bridges, ports and power plants.
Digital connectivity increasingly determines who can access financial services, education, government services and markets.
PNG’s Medium-Term Development Plan 2023–2027 includes the digitisation of government systems as part of its broader development agenda.
For businesses, better digital infrastructure can reduce geographic barriers. A company in a smaller town can potentially communicate with customers, suppliers and service providers without being physically close to them.
Digital access can also support financial inclusion. ADB estimates that around 80% of PNG’s population is unbanked or underbanked and has committed funding to expand access to financial services.
What Does Infrastructure Mean for PNG’s Long-Term Economic Future?
The bigger question is whether infrastructure investment can help PNG build an economy that is broader and more resilient.
Natural resources will remain important. Major projects such as Papua LNG and Wafi-Golpu are expected to contribute to future economic activity, while the government continues to position the energy and resources sector as a major source of investment and revenue.
But infrastructure can determine whether that investment creates wider economic links.
ADB’s new 2026–2030 country partnership strategy places transport and energy connections alongside health, education, public finances and private-sector development. Its planned 2026–2028 pipeline is about $1.85 billion, with transport accounting for 47% and energy for 12%.
For Papua New Guinea, building for tomorrow therefore means building connections today. Roads need to reach productive communities. Electricity needs to reach businesses. Digital networks need to reach people. Public investment needs to support private enterprise rather than operate separately from it.
If those pieces begin working together, infrastructure can do more than close physical gaps. It can help PNG turn economic growth into broader participation, stronger businesses and more opportunities for the people who have historically remained furthest from the country’s main centres of economic activity.
