Industry Insight
Construction is among the top 5 most targeted industries in NZ for business email compromise fraud.
Why Construction Businesses Need Cyber Insurance
The construction sector is increasingly targeted as it digitises operations. Project management software, contractor payment systems and building information models (BIM) all represent valuable targets. Invoice fraud via email compromise is a significant risk when large payments are involved.

Why Construction is a Top BEC Target
The construction industry in New Zealand has become one of the most targeted sectors for business email compromise fraud. The reason is straightforward: construction projects involve large, time-sensitive payments between multiple parties — principal contractors, subcontractors, suppliers, consultants and clients. These payment flows are complex, often involve new banking relationships, and are conducted under time pressure — all conditions that favour social engineering fraud.
A criminal who gains access to email communications between a contractor and their subcontractors can monitor payment cycles, timing and amounts before intercepting a large progress payment by substituting fraudulent banking details. Single-incident losses of $50,000 to $500,000 are not uncommon in the NZ construction sector.
Building Information Modelling and Design Data Theft
The construction sector's adoption of Building Information Modelling (BIM) and digital project management tools has created new forms of valuable intellectual property. Detailed building designs, site data, structural calculations and project specifications represent significant commercial value — and in some cases, national security sensitivity for infrastructure projects. Theft of this data can enable competitors to undercut on future tenders or give state-sponsored actors insight into critical infrastructure vulnerabilities.
Ransomware Targeting Project Management Systems
Project management platforms like Procore, Aconex and similar tools store the complete documentation trail for active construction projects: contracts, variations, RFIs, inspection records and programme updates. A ransomware attack encrypting this data can bring entire projects to a halt, preventing site supervisors from accessing approved drawings, delaying inspections, and triggering penalty provisions in contracts. Recovery of encrypted project data — even with backups — typically takes several weeks.
Subcontractor Supply Chain Risk
Large construction firms are increasingly targeted through their smaller subcontractors, who often have less sophisticated cybersecurity controls. Criminals compromise a subcontractor's email account and use it to conduct BEC fraud against the principal contractor — the messages appear legitimate because they genuinely originate from the subcontractor's email system.
Cyber Insurance for Construction
A cyber insurance policy for NZ construction businesses should specifically address: social engineering fraud and invoice payment diversion, BIM and project data breach response, ransomware affecting project management systems, business interruption during data recovery, third-party liability for subcontractor data exposure, and supply chain breach response. The cyber crime sub-limit is particularly important for construction — ensure it reflects the scale of payments your business typically handles.

Frequently Asked Questions
Does cyber insurance cover invoice fraud where we paid the wrong account?
Yes, if your policy includes social engineering fraud or cyber crime cover. This is specifically designed to respond to BEC and invoice fraud. Confirm the sub-limit reflects the scale of your typical project payments — standard limits may be insufficient for large contracts.
Are subcontractor companies covered separately?
Subcontractors need their own cyber insurance. Your policy covers your business's losses and liabilities. However, some larger principal contractors are beginning to require subcontractors to hold minimum cyber insurance levels as a condition of engagement.
Is design IP theft covered by cyber insurance?
A data breach that results in theft of your BIM files, architectural drawings or engineering designs is covered under cyber insurance — including forensic investigation, notification obligations if personal data is involved, and third-party liability. Separate IP insurance may be needed for the commercial value of the stolen IP itself.
What verification processes can prevent BEC fraud in construction?
Implement a mandatory callback verification process for any change in banking details — calling a known number for the counterparty, not one provided in the email. Dual authorisation for payments over a threshold is also effective. Cyber insurance provides the financial backstop when these controls fail.
