Christchurch was well served before the earthquakes by several significant companies. "They are picking up the slack at the moment and we are supplying workers to them."
But once the rebuild goes vertical in a big way and construction starts on the anchor and major government-funded projects, Eder thinks there will be greater need for site managers, steel fixers and concreters.
He says the residential market is busy, particularly in suburban sub-divisions, adding that commercial is an interesting beast. "A year ago, we were saying it would probably be very busy now. Now we are all probably saying it will be busy in a year or so." Eder says the Christchurch rebuild is an unprecedented situation with developments up to 10 times the usual size. And the timing of the anchor projects is another factor that could create a bottleneck. "The timeline around the completion of the anchor projects is unrealistic. They are talking about having them all under way at the same time and there just isn't the capacity in the city."
The Institution of Professional Engineers New Zealand (IPENZ) says a changing of the guard is taking place in the Christchurch rebuild.
IPENZ Christchurch branch chairman Chris Maguire says several engineers flown in to complete design work after the 2011 earthquakes are returning to Wellington or Auckland because of growing demand there and new engineers are arriving in Christchurch to replace them.
He says dozens more structural and geo-technical engineers are needed for the vertical rebuild over the next one to two years. However, design engineers are able to work remotely rather than being based in Christchurch.
IPENZ chief executive Andrew Cleland says some of the work in Christchurch is not able to be carried out as quickly as people would like because of the high volume of work and not enough engineers with the right competence for technically demanding work. Immigrant engineers have helped meet some of the demand but take time to get up to speed with local requirements for critical work.
The shortage of engineers is not confined to Christchurch though. There is a nationwide demand for engineering expertise. Engineering disciplines at Immigration New Zealand in the category of long-term skills' shortages include structural, civil, chemical, electrical and mechanical.
IPENZ says the shortage of engineers is the consequence of a long-term under-investment in engineering graduates. The percentage of total graduates who choose engineering is lower in New Zealand - 6 per cent - than any other country in the OECD, which averages 13 per cent.
Cleland says IPENZ has warned about this shortage for many years and is promoting the profession to the younger generation by encouraging the uptake of science and technology subjects in secondary schools.
The Ministry of Business, Innovation and Employment website (Immigration) also flags a need for quantity surveyors and project managers, and some demand for tradesmen such as painters and carpenters.
Canterbury labour market figures reflect the amount of work being done in the rebuild with CareersNZ noting the jobless rate is 4.4 per cent as opposed to the national figure of 6.4 per cent. To help address the need for workers, the Skills and Employment Hub has been set up by the ministry, the Canterbury Earthquake Recovery Authority, the Ministry of Social Development and the Tertiary Education Commission.
