How does BusinessNZ verify businesses?

We're rolling out NZBN-backed verification. Verified badges will indicate a listing has passed ownership and registration checks against the official New Zealand Business Number register.

Is BusinessNZ free to use?

Yes — searching and browsing the directory is free for consumers. Businesses can claim and enhance their listing via the For Businesses page.

Can I filter by suburb or region?

Yes. Browse by region and suburb from our location pages, or use search filters to narrow results by category, badges, and opening hours.

Do I need a licensed plumber for every job?

For most structural, electrical, gas, or plumbing work in New Zealand, yes — restricted building work and licensed trade work legally requires a registered practitioner, and unlicensed work can void your insurance and create resale issues. For minor cosmetic jobs the rules are more relaxed, but when in doubt, ask.

Is every legitimate NZ business required to have an NZBN?

Yes — since 2013, every business registering with a New Zealand government agency (including the Companies Office and Inland Revenue) is automatically issued an NZBN. A business with no NZBN at all is unusual and worth asking about directly.

Is it normal for tradespeople to ask for a deposit?

Yes, deposits for materials are standard practice, especially for larger jobs. The distinction is whether it's requested against a written quote with a business name attached, versus an informal cash request with no documentation.

Should I ask these questions over the phone or in writing?

Ask verbally first to gauge how confidently they answer, then get the key details (quote, registration number, timeframe) confirmed in writing or email before work starts.

What happens if unlicensed work is done on my house?

Unlicensed restricted building work, electrical work, or gasfitting can fail council inspections, void your home insurance for related damage, and create serious problems when you try to sell — buyers' solicitors routinely check for compliance documentation.

Should I ignore a business with a few negative reviews?

Not necessarily — look at how old the negative reviews are, whether they're a pattern or a one-off, and how the business responded. A single dated negative review with a thoughtful response is far less concerning than several recent, unanswered ones.

Should I always go with the middle-priced quote?

Not automatically — it's a reasonable default when the quotes are otherwise similar in scope and the tradesperson checks out on licensing and reviews, but it shouldn't override those checks.
