The scale of fuel cost pressure on New Zealand’s construction sector has been laid out in sharp detail by survey data from the Combined Building Supplies Co-operative (CBS). The findings show that 84% of respondents experienced moderate to significant fuel price impacts over the past month, with two-thirds reporting that suppliers had increased pricing or introduced fuel-related surcharges. More than 60% of those builders said they were absorbing these increases themselves rather than passing them on to clients.
CBS chief executive Carl Taylor summarised what the numbers represent in practice: costs build quickly, builders absorb them, margins disappear, and eventually the pressure flows through into higher prices for the end customer. In the meantime, the businesses caught in the middle are running on less.
Fixed-Price Contracts Are the Flashpoint
The most acute risk is concentrated in builders and contractors operating under fixed-price contracts signed before the current round of cost increases. Survey respondents flagged that projects priced months ago are now at serious financial risk, with one noting directly that companies already on thin margins face liquidation if cost movements continue and there is no mechanism to renegotiate.
This is not a hypothetical risk. Construction insolvency rates in New Zealand have been running at elevated levels, and the combination of fuel costs, material price volatility, and the absence of escalation clauses in many residential contracts is the precise set of conditions that pushes stressed businesses over the edge.
Infrastructure NZ Issues a Warning
Infrastructure NZ chief executive Nick Leggett has added the infrastructure sector’s perspective to the conversation, cautioning that fuel disruption threatens continuity across the nationwide project pipeline. Halting funded infrastructure programmes in response to cost volatility would worsen long-term economic consequences rather than provide relief, he has argued.
The risk Leggett identified is a damaging cycle: rising costs compress margins, contractor confidence drops, clients pause or defer projects, and industry investment slows. The momentum gains that the construction sector was beginning to build coming out of a difficult period could be lost if the current cost environment persists without a structural response.
What Builders Can Do Now
For builders currently pricing work, the priorities are clear: understand which contracts include escalation mechanisms and negotiate for them where they do not, communicate proactively with clients about cost movements, and avoid locking in fixed-price agreements without some form of protection against material and fuel price movements that are demonstrably beyond the contractor’s control.
