Overseas products yet to gain traction

Overseas-sourced building products are yet to make a significant impact on the construction market, despite sustained pressure from rising build costs and ongoing concerns about affordability across the sector.

While parallel importing and direct offshore procurement are legal and increasingly accessible, industry commentary suggests uptake remains limited, with most projects still relying heavily on established local supply chains and approved distribution networks.

The issue is gaining attention as construction costs remain elevated and developers look for ways to reduce material spend without compromising compliance or build quality. However, the practical barriers associated with using imported building products continue to limit widespread adoption.

A parallel imported product refers to a genuine item sourced from overseas and sold in New Zealand outside the manufacturer’s authorised distribution network. While common in consumer markets, the practice operates differently in construction, where products must meet Building Code requirements and be supported by acceptable compliance documentation.

Despite the theoretical cost advantages, recent industry feedback indicates overseas alternatives are not yet significantly disrupting the domestic supply landscape. Local distributors and manufacturers continue to dominate procurement pathways, particularly in consented residential and commercial projects.

One of the key constraints is compliance. Building products used in New Zealand must be able to demonstrate that they meet performance requirements under the Building Code. Products supplied through authorised channels typically include local technical data, certification pathways, and established documentation that supports the consenting process.

In contrast, parallel imported products may not always carry the same level of New Zealand-specific assurance material, even when the product itself is identical to versions sold through official channels. That can create additional work for designers, engineers, and builders when seeking consent approval.

Building consent authorities also rely on established evidence frameworks such as CodeMark certification and BRANZ appraisals when assessing product suitability. Where this information is absent or incomplete, additional verification may be required, potentially slowing approval timelines.

The challenges are most pronounced in building envelope and safety-related systems, including cladding, waterproofing membranes, insulation, and services such as plumbing and electrical components. These areas carry higher performance risk and are more closely scrutinised during consent and inspection processes.

Lower-risk categories such as fixtures, fittings, appliances, and non-structural finishes are more commonly sourced through parallel import channels, where compliance risks are more manageable and replacement or remediation is less complex.

The muted impact of overseas products comes at a time when the construction sector is under sustained financial pressure. Industry commentary has pointed to escalating build costs, constrained margins, and the potential for reduced activity if affordability challenges persist.

However, despite these conditions, there is little evidence to suggest that parallel importing is currently reshaping procurement practices at scale. Instead, the sector continues to rely on established supply chains, with compliance certainty and documentation support remaining key decision-making factors.

As cost pressures continue, overseas procurement options are likely to remain part of the discussion. But for now, industry behaviour suggests they are not yet displacing traditional supply models in any significant way, particularly in regulated building categories.
