Rise of Chinese Imported Tiny Homes - What You Need to Know
With housing costs continuing to rise across New Zealand, more Kiwis are exploring tiny homes as a faster, more affordable way to get on the property ladder. One growing trend is the surge in imported tiny homes from China - but while the price tags might be appealing, the risks are real.
So what should you know before buying one?
The Risks - Why Cheaper Isn’t Always Better
Chinese factories are producing thousands of prefab homes each year - many of which are being marketed to New Zealand buyers. While some importers do a great job of adapting these units to meet NZ requirements, most come in as-is and fall short in several key areas.
Here are some of the most common concerns:
Non-compliance - Many units don’t meet the New Zealand Building Code, especially around weatherproofing, structure, and safety. They often require major modifications before they can be consented or lived in legally.
Cheap materials - Lower-grade steel, insulation, and cladding are commonly used to keep costs low. This can lead to cold homes, rusting frames, and shorter lifespans.
Poor after-sales support - Once the unit is delivered, good luck getting help. Many offshore suppliers disappear after payment - and returns or repairs are almost impossible.
Common Issues Reported by NZ Buyers
Leaks from thin roofing and poor flashing installs.
Warped flooring or walls from untreated or low-quality timber.
Electrical faults due to non-compliant or unverified systems that don’t meet NZ safety standards.
These issues aren’t just annoying - they can lead to failed consents, unsafe living conditions, and costly fixes down the track.
The Exceptions - Importers Doing It Right
Not all imported homes are low quality. A few New Zealand-based companies are working closely with offshore factories to lift standards and ensure local compliance.
Expanders.co.nz - Offers a range of homes fully engineered for New Zealand conditions. Units come with PS1 documents, fire safety design, structural sign-off, and plumbing/electrical certifications to match NZ regulations.
Same Day Granny Flats - Known for being upfront about what is and isn’t compliant. They help buyers navigate the building consent process and back their units with local support.
These businesses take the extra step to protect their customers - ensuring you’re not left with a cheap shell that can’t be legally lived in.
Bottom Line - Ask the Right Questions Before You Buy
Chinese prefab homes can be a great opportunity - if you do your homework. Before committing to any purchase, make sure the importer can provide:
Engineer-approved structural plans
A PS1 certificate from a licensed NZ engineer
Proof of compliance with the NZ Building Code
Warranties and local support for delivery, repairs, and replacements
If they can’t - walk away. You’ll save yourself from big financial and legal headaches.
Buying a home - even a small one - is a major decision. If you're looking at Chinese imports, make sure you're not just chasing a low price. Go with a supplier who understands the New Zealand market and can stand behind their product.
