Discover the warranty coverage for WCTNZ® building systems products. This page explains what may be covered, what is not covered, and how to make a warranty claim.
For composting toilet warranties, please see Composting Systems Warranties. For general product warranties, please see General Warranties.
Warranty protection applies by brand, model, building type, and component. Coverage is generally limited to defects in materials or workmanship during normal use, subject to the relevant manufacturer warranty period, installation requirements, foundation or fixing requirements, product manual, evidence supplied, and applicable law.
Nothing on this page excludes or limits any rights or remedies that cannot lawfully be excluded under New Zealand law.
WCTNZ® building systems may involve site-specific foundation, fixing, anchoring, assembly, access, weather exposure, public-use, structural, and maintenance considerations.
Warranty cover may be affected if the building system is installed, altered, moved, fixed, maintained, or used outside the supplied instructions, project documentation, engineering information, or agreed conditions.
Where a project involves public use, commercial use, remote sites, wind exposure, corrosion risk, coastal conditions, or harsh environmental conditions, customers should ensure the selected building system, installation method, and maintenance pathway are suitable for the site.
The following items are generally not covered by warranty. Brand-specific and project-specific terms may include additional exclusions or requirements.
Damage from improper installation, misuse, or alterations
Faults due to external power supply incompatibility, including off-grid inverter issues
Normal wear and tear or consumables
Labour charges and parts for issues found unrelated to manufacturing defects
Labour charges for issues found within the warranty period unless expressly covered in writing
Freight, return shipping, delivery of replacement parts, or logistics costs unless otherwise stated
Damage caused by site movement, poor foundations, unauthorised relocation, unsuitable anchoring, excessive loads, vandalism, storm events, fire, flood, or other external causes unless expressly covered in writing
