Why reviews matter more than ever
When someone searches "plumber Auckland" or "accountant Wellington", Google ranks local results on relevance, distance, and prominence. You can't do much about distance. Relevance is mostly set-and-forget. Prominence, built largely through reviews, is where a business can actually move. Whitespark's Local Search Ranking Factors survey ranks review signals second only to your Google Business Profile itself, and rising year on year.
Review count, average rating, how recent the reviews are, and whether you respond to them all feed into how prominently Google shows your business. A deeper review base usually beats a higher average built on a handful of ratings, which is why a business with twelve reviews at a perfect 5.0 often ranks below one with dozens at 4.8.
Two things have raised the stakes since we first published this guide. Reviews now carry much of the weight that backlinks used to carry in local search. And AI assistants (ChatGPT, Gemini, and Google's own AI results) read review text in full when someone asks them to recommend a business. Darren Shaw of Whitespark, after months of testing Google's AI results, puts it plainly: when the AI recommends one business over another, the reason is usually something a reviewer said. A customer who writes "fixed our hot water cylinder in Papakura the same day" is feeding those tools exactly the detail they use to match you to the next person's question.
The basics: a system, not a hope
Businesses with long review histories ask, every time, in a way that takes the customer under a minute. That is the whole system, and it has four parts.
Ask at the right moment, from a number they know
The best moment to ask is right after the job is done, while the experience is fresh. For most trade and service businesses, that means asking in person at the end of the job or as you hand over an invoice. Most satisfied customers are glad to help when asked directly. Most will never get around to it if you wait and hope.
"We rely heavily on Google reviews and I'd really appreciate one. Say whatever you think, in your own words. That's the bit that helps the next person. Takes about a minute."
The second sentence is the one that earns its keep, and it is the difference between "Great service, 5 stars" and "our heat pump died on a Friday, they had a new one in by Tuesday". Ask for their experience in their own words: Google allows a business to ask for genuine reviews, but its policy says merchants should not "request that specific content be included" or try to influence the rating. It names asking only the customers you expect to be happy as a violation too, so ask everyone.
If you follow up by text, send it from the mobile number the customer already has for you. Caleb Ulku, who runs a US agency working with home-service businesses, reports a gap most owners would not believe:
of customers act on a review request texted from the tradesperson's own number. The same ask sent by generic review software: about 5 per cent.
A text from "Dave the builder" is personal; a platform the customer has never heard of is marketing. Send it the same day, because the further you get from the positive experience, the fewer reviews come back.
Make it easy
Every extra step between the ask and the review costs you conversions. Get your Google review shortlink (open your Business Profile, click "Share profile", copy the link) and put it in the follow-up text or email. It takes customers directly to the review box with no searching required. Plain text works better than designed HTML emails, which read as marketing.
Add a QR code linking to the same place on every invoice and receipt. Most invoicing software (Xero, Invoice Ninja, etc.) lets you add a footer image or note, and a customer who pays and then thinks "that went well" has a direct path right there on the document.
Physical review prompts
If you have a reception area, waiting room, or front counter, a physical review card works continuously without any effort from you. NFC tap cards let customers tap their phone on a card and go straight to your review page; QR codes on printed cards or posters do the same for customers who prefer scanning. Google's own guidance endorses the mechanic: a link or QR code the customer follows on their own phone. Several NZ suppliers sell both; search for NFC review cards or QR review cards.
One rule keeps this safe: the review happens on the customer's own phone, from their own account, and it is fine if they finish it later at home. What gets review clusters filtered is volume arriving through one device or connection, so never set up a shared tablet at the counter and never post on a customer's behalf. A card that starts the review on their phone does neither.
Reply to every review
Responses have always shaped how the next customer reads you. Now the machines read them too: AI assistants take your replies into account alongside the reviews themselves. Write them for the human, thank people for something specific, and never keyword-stuff a reply; a response that reads like SEO copy costs more trust than it earns. For the harder cases, see How to Respond to Negative Google Reviews.
The advanced layer: what your reviews actually say
Once the stream is flowing, the words become the asset. An AI assistant asked for a recommendation matches the customer's exact situation against review text. Someone asks for a plumber and adds "we've just had new floors laid, I don't want them wrecked", and the assistant goes hunting for a business whose reviews mention tidiness or protecting the house. Every specific your reviews name is a question you can win.
"Most of the things that Google cites, and the reasons that they recommend this business over that business, is usually because of what was said in reviews."
Darren Shaw, Whitespark, August 2026Ask for the story
The prompt in the ask above does most of this work: to an AI reading your profile, a five-star rating with no words is close to worthless, and one line of detail changes that. The refinement is who you ask, since you cannot steer what they write. If every ask goes to an emergency callout, the reviews cluster on speed and nothing else. Ask across the range of jobs you do, the planned installations as well as the Friday night breakdowns, and the detail spreads itself across the kinds of work you want to be found for.
Put your best reviews on your website
A review naming a specific job belongs on the page for that service, not just on Google. Embedding it there pairs your claim with independent evidence in a customer's own words, on the exact page Google and AI tools read when deciding whether you do that work. Most business websites never make the pairing.
Don't stop at Google
Google matters most, but it is no longer the only review index that counts. ChatGPT leans on Bing when it looks up local businesses, so a Bing Places listing with even a handful of reviews gives you presence where a growing share of recommendations now happen. AI tools also give surprising weight to independent review platforms precisely because they are harder to farm than Google; overseas analysts keep finding AI local results citing them ahead of far bigger sites. In New Zealand that means Builderscrack and NoCowboys for trades, Trade Me Services, and whatever platform your industry actually uses; AccessNZ, a sister site of ours, keeps a curated index of NZ directories and review platforms if you're not sure what exists for yours. Point every fifth or sixth happy customer at one of them. Existence is enough there.
Own the search for your own name
Before calling you, a good share of customers run one more search: your business name plus "reviews". The AI assistants run the same check before recommending anyone. What comes back is whatever independent pages exist about you, so it pays to give that search something solid to return.
The platforms above cover most of it. In New Zealand, your Top5.nz listing helps here too: it is an independent page carrying a review-derived editorial summary of your business, and claiming it is free. Businesses on the paid tier get a public profile page as well, plus a longer write-up and a field that tells us which of the things your reviews say to lead with. None of it changes your position, which is set by the reviews. One limit of ours: a business outside the visible ten in its category has no Top5.nz page for a name search to find, and we rescore on a cycle, so a new review shows on Google before it shows with us.
Ask the AI what your reviews say
The assistants that read your reviews will also summarise them for you, free.
Ask ChatGPT or Gemini, a few times each, and keep what recurs:
- "What do people complain about in reviews of [your business]?" A recurring complaint is a business problem surfaced for nothing, and fixing it is worth more than any tactic in this guide.
- "What do customers complain about in reviews of [your trade] in [your city]?" Every common gripe becomes a line for your website that the next matching search can find.
- "Which review sites do you reference for [your industry]?" It is reporting on itself, so treat the answer as a lead to check, but it is the quickest way to find which platforms are worth your effort.
What not to do
Never offer a reward. Anything of value given for reviews (discounts, entries in a draw) violates Google's review policies and can get your listing suspended. Google has also become better at detecting reviews that arrive through the same device or connection in quick succession, which is the fingerprint of purchased campaigns.
Review gating is out too. Sending requests only to customers you expect will rate you highly violates Google's guidelines, and if Google detects it, the penalty can extend to your legitimate reviews being removed. Ask all customers.
Fake reviews, bought from a service or written by friends and family, read as false to real customers, and the short-term gain is not worth what they now risk.
Fake reviews are illegal in New Zealand, not just against Google policy. Posting or commissioning them is misleading conduct under the Fair Trading Act, and in 2026 the District Court ordered The TV Shop to pay a $1.1 million penalty for conduct that included staff posting reviews without disclosing who they worked for.
A perfect 5.0 is not the goal
A flat 5.0 rating with a long review history can work against you. Consumers have learned that nobody is perfect, and a wall of identical five-star praise reads as filtered or fake. Ulku puts the conversion peak between 4.7 and 4.9, ahead of a perfect score. Our own data across 3,269 ranked NZ businesses shows the average is 4.86, and businesses at the top of their category almost all carry a few negative reviews.
A visible, calm owner response that fixes the problem is one of the strongest trust signals a listing can carry.
How many reviews do you actually need?
It depends on the category more than the city. Our analysis of what it takes to rank in the Top 5 found the average review count at position 5 ranges from around 11 for architects and 23 for graphic designers up to 214 for plumbers and 263 for vets. Reaching first place is a different problem again: across the seven markets we covered in July 2026 the leading plumber averages 804 reviews against 214 at position 5.
More important than a single target is consistency. A business adding 5 to 10 reviews per month signals to Google that it's actively trading. A business with 200 reviews that hasn't had a new one in 18 months has a recency problem.
The same signals drive our rankings. Top5.nz scores businesses on public review data alone: rating, volume, how fast new reviews arrive, and what the reviews say. A steady stream of detailed reviews moves you up both Google and the Top 5 page for your category. If you're ranked, claiming your listing is free and shows you which of those four is holding you back.
