Builder due diligence guide
Where to check a builder in NZ
No single website tells you everything about a builder. The useful approach is to combine homeowner discussion, public registers, reviews, association checks, and background reports before you sign.
Start with the question you are trying to answer
A homeowner usually searches for a builder because something feels high-stakes. You may be close to paying a deposit, choosing between quotes, or trying to understand a comment you saw online. Those are different questions, so they need different sources.
A Google review can show recent customer sentiment. An LBP search can confirm licence status. The Companies Register can show legal company details. A discussion layer can show what homeowners have said over time. A report product can package public-record checks into one document. None of those sources should be treated as the whole answer.
The strongest builder check is a layered check. Start broad, confirm official records, separate trading names from legal companies, and keep discussion in context.
Why use Builder Review NZ
Built for the homeowner research step before signing.
Most check tools answer one narrow question. Builder Review NZ is built around the messier question homeowners actually have: what context exists around this builder, company, owner, brand, or topic before I commit?
Name matching across messy inputs
Search by builder, company, owner, brand, franchise, topic, or region instead of needing the perfect legal name before you start.
Records treated as context
Use discussion alongside public-record signals so a single review, licence check, or company record does not carry the whole decision.
Comparison
Where each builder-check source fits
Use this table as a decision guide, not a ranking. The right source depends on whether you are checking reputation, licensing, company status, project feasibility, or a named builder's wider context.
Best for
Homeowner discussion, historical context, entity matching, and public-record signals.
Use when
You have a builder, company, owner, brand, or location to research before signing.
Watch for
Discussion is context, not a verdict. Public-record coverage will become richer as snapshots mature.
Best for
Public-record-style builder and tradie background reports, monitoring, and verified tradie profiles.
Use when
You want a structured report based on official records and are comfortable with a report-led product.
Watch for
It appears less focused on homeowner discussion, historical reputation context, and forum-style evidence.
Best for
Manual trade checks, company checks, credit checks, and criminal-history-style screening.
Use when
You want a check process where the tradesperson may need to participate.
Watch for
More service-led and higher friction than a public search or discussion-led research workflow.
Best for
Project feasibility, consent questions, plan checking, building rules, and homeowner education.
Use when
Your main question is whether the project, plan, or consent path makes sense.
Watch for
It is not mainly a named-builder reputation, company, owner, or discussion lookup.
Best for
Finding available tradies, posting jobs, reading job-completion reviews, and comparing profiles.
Use when
You are still looking for someone to quote or complete a job.
Watch for
Marketplace reviews do not replace company, director, licence, insolvency, or discussion research.
Best for
Business ratings, trade profiles, and customer review history.
Use when
You want a review-site view of a trade or local business.
Watch for
It is a ratings directory, not a full public-record or homeowner-discussion research layer.
Best for
Checking Licensed Building Practitioner status and licence class.
Use when
Restricted building work is involved and you need to confirm licensing.
Watch for
Licensing does not prove workmanship quality, business health, or customer experience.
Best for
Company status, directors, shareholders, removed companies, external administration, and banned directors.
Use when
You know the legal company name, NZBN, or director name and want official corporate records.
Watch for
The raw register can be hard to interpret when builders use trading names, brands, or related companies.
Best for
Association membership, qualification signals, and guarantee availability.
Use when
You want to confirm whether a builder belongs to an industry association.
Watch for
Membership is one trust signal. It is not the same as independent due diligence.
Best for
Quick social proof, recent customer comments, and local homeowner anecdotes.
Use when
You need a fast first impression or want to ask people in your area.
Watch for
Reviews and posts can be fragmented, hard to verify, and disconnected from legal company records.
How to use the sources
A practical checking sequence before you sign
Start with the exact name you have
Homeowners often only have a trading name, franchise name, website, quote header, company name, owner name, or NZBN. Search all of them, because one builder can appear under several labels.
Separate people, companies, and brands
A franchise brand, local operator, legal company, and individual director are different entities. A useful check keeps those layers separate instead of treating every mention as the same builder.
Treat reviews and discussions as signals
Homeowner discussion can reveal patterns, but it should not be treated as a court finding. Look for consistency, source labels, dates, and whether any public record supports the concern.
Verify official records directly
Use official registers for licensing, company status, director history, insolvency notices, and formal decisions. A polished website or strong review score should not replace those checks.
Read the contract before the deposit
Check scope, exclusions, provisional sums, variations, payment stages, delay rules, defects, and guarantees before you rely on a fixed price or a verbal promise.
Key distinctions
What each check can and cannot prove
A licence check is not a quality guarantee
An LBP record can confirm that a practitioner is licensed in a class. It does not prove the builder communicates well, prices variations fairly, or has a healthy company behind the quote.
A review is not a public record
Reviews and discussion can surface patterns, but they need context. Check dates, names, whether the same legal company is involved, and whether any official record supports the concern.
A company check is not the whole builder
A legal company may be one part of a wider trading history. Look for directors, related companies, brands, franchise operators, and past names when the project is high value.
A guarantee is not the whole safety net
A Master Build, NZCB, or builder guarantee can help, but you still need to check cover terms, exclusions, timing, and the builder behind the paperwork.
A fixed price can still move
A contract may include allowances, exclusions, provisional sums, and variation rules that affect the final price. Read those clauses before signing.
FAQ
Common questions about checking builders
What is the best place to check a builder in New Zealand?
There is no single best place for every check. Use LBP for licence status, Companies Register for company records, Builder Review NZ for homeowner discussion and context, and report services for structured background checks.
Is a Licensed Building Practitioner check enough?
No. An LBP check confirms licence status and class, which matters for restricted building work. It does not tell you whether the company is solvent, whether related companies exist, or what homeowners have discussed.
Are builder reviews reliable?
Reviews are useful, but they are only one signal. Look for patterns across several sources, check whether the review relates to the same company or local operator, and compare it with official records.
Should I use CheckMyBuilder or Builder Review NZ?
Use CheckMyBuilder if you want a public-record-style report product. Use Builder Review NZ when you want homeowner discussion, historical context, and named-entity research around a builder, company, owner, brand, or topic.
Where does Building Guide fit?
Building Guide is better suited to project feasibility, consent questions, building rules, and plan checking. It is not mainly a named-builder reputation or public discussion lookup.
Next step
Search the discussion layer first.
If you already have a builder name, company name, owner name, brand, or location, start with homeowner discussion. Then use official registers to confirm the record.
