"It's being driven by about six separate factors," says Gibson.
Inflation, a shortage of materials, the extremely high volume of construction, the shortage of labour, the challenges of gaining access to finance and ongoing impact of the pandemic have all combined to exacerbate legacy issues that have long simmered under the surface.
Gibson says the impact has left many businesses struggling to make ends meet at a time when the industry is booming.
The stories reported thus far in the media appear to only be the tip of the iceberg when it comes to the struggles across the industry.
"Andrew Bayly, the National Party's construction spokesperson, says more than 100 building businesses have gone into liquidation this year alone," says Gibson.
Master Builders Association national vice-president Johnny Calley this week warned that more companies would go under due to the sharp increase in the price of materials.
The high price of building materials in New Zealand has again raised questions about the concentration of market power among a small number of large organisations.
It's been reported that 94 per cent of the GIB market controlled by the GIB board, 89 per cent of the glass wool supply controlled by three firms, and just two companies control 85 per cent of the concrete industry.
"In November, the Government asked the Commerce Commission to look into this," says Gibson.
"And one of the Jarden analysts Grant Swanepoel looked at Fletcher's dominance recently and found that it held 94 per cent of the share on GIB boards via Winstone Wallboards, 55 per cent of the cement market and 40 to 50 per cent of glass wool insulation. And Fletcher's Placemakers has about a quarter of the merchant market in terms of small to medium-sized buildings."
Gibson adds that Carters has a dominant position in terms of supplying materials to businesses in the building industry.
These large companies have both made submissions arguing that there are numerous factors that contribute to the high cost of building in New Zealand, including consent processes and taxes.
Ross Taylor, Fletcher's chief executive, told the commission materials were but a small portion of overall house price costs, making up only 19 per cent of the cost of a new house. Gibson said Taylor urged the Commission to look into land and consent costs as well as taxes for an indication of why prices were so high.
In its submission, Carter Holt challenged the idea of having too much market power, saying there were numerous other competitors in the market.
Gibson compares the Commerce Commission market study to what happened in the supermarket industry recently.
This has since led to the Government rolling out a raft of changes in an attempt to increase competition in a market dominated by two large companies.
Whether the Commerce Commission findings do eventually result in changes will ultimately depend on the will of the Government.
"Once the Commerce Commission releases its findings, it's really a political decision for the Government about whether it should step in and, if so, how far it should move?"
The fallout from the six-pronged assault hitting the industry won't be limited to construction.
"Construction often shows stress ahead for other sectors," says Gibson, warning the pressures facing the building sector are being felt across the economy at the moment.
