Construction Industry Faces 15% Labour Shortage as Major Infrastructure Projects Compete for Workers

New Zealand’s construction industry is experiencing its most severe labour shortage in over a decade, with unfilled positions reaching 15% of total workforce demand as major infrastructure projects compete for the same pool of skilled workers. The shortfall is driving wage inflation and threatening project timelines across both public and private developments.

Latest industry data shows the construction sector is short approximately 22,000 workers, with electricians, plumbers, and construction managers in highest demand. The shortage has intensified as the government’s $30 billion infrastructure programme ramps up alongside a recovering residential building market.

“We’re seeing unprecedented competition for skilled labour between major infrastructure projects and residential developers,” says Construction Industry Council chief executive Graham Burke. “Wage rates have increased 18% in the past 18 months alone, and we’re still struggling to fill critical positions.”

Infrastructure Boom Drives Demand

The government’s accelerated infrastructure spending, including the Auckland light rail project and nationwide hospital upgrades, has created a perfect storm of labour demand. According to Building and Construction Minister’s office, the finding showed infrastructure projects alone require an additional 8,000 skilled workers over the next two years.

Major construction firms report difficulty retaining staff as workers move between projects chasing higher pay rates. Fletcher Building’s residential division has increased starting wages for apprentice carpenters by 22% since January 2025, while still facing a 12% vacancy rate.

“The private sector simply cannot compete with government contract rates in many cases,” explains Master Builders Association president David Kelly. “We’re losing experienced foremen to infrastructure projects offering 25-30% pay premiums.”

Skills Gap Widens Despite Immigration Reset

The labour shortage persists despite the government’s 2025 immigration reset, which prioritised construction workers for residence pathways. Immigration data shows only 3,200 construction workers gained residence in the past 12 months, well below the 8,000 target.

Industry Training Organisation BuildingIQ reports apprenticeship completions have increased 8% year-on-year, but remain insufficient to meet demand. The organisation warns that without intervention, the skills gap could reach 30,000 workers by 2028.

“We’re training more apprentices than ever before, but we’re also losing experienced workers to retirement faster than we can replace them,” notes BuildingIQ chief executive Sarah Mitchell. “The average age of our workforce continues to climb, creating a demographic cliff we’re struggling to address.”

Regional Disparities Create Additional Pressure

Auckland and Wellington face the most acute shortages, with vacancy rates exceeding 18% for electrical and plumbing contractors. Regional centres traditionally supplied skilled workers to main centres, but local infrastructure projects now retain more workers in smaller markets.

Hawke’s Bay reconstruction efforts following Cyclone Gabrielle continue drawing workers from other regions, while Canterbury’s ongoing rebuild maintains steady demand. This has created wage inflation across all regions, with even small provincial projects facing 20-30% cost increases for specialist trades.

Housing developers warn the shortage could slow the government’s 100,000 homes target, with several major developments already experiencing six-month delays due to labour constraints.

Outlook Remains Uncertain

Industry leaders expect the labour shortage to persist through 2027, with no quick solutions apparent. The government is considering fast-tracking trade qualifications and expanding working holiday visa categories to include construction workers.

However, concerns remain about maintaining quality standards while addressing quantity demands. Building consent authorities report increased non-compliance rates as inexperienced workers enter the market, potentially creating longer-term quality issues.

The Construction Industry Council projects wage growth will moderate to 8-12% annually once immigration pathways fully open, but warns project delays and cost overruns will continue until labour supply stabilises.
