We pulled the Google review profiles of every automotive workshop we could find in New Zealand: 1,947 businesses, 149,248 reviews. Then we hand-read and labelled 1,893 of them, line by line, and re-checked every number against a fresh sample from different regions. What came out is the clearest picture anyone has published of how Kiwis actually judge their mechanics, and the gap between a 4.4-star shop and a 4.9-star shop is far bigger than half a star suggests.
Seven findings from 149,248 reviews
- • At a 4.4-star workshop, roughly 1 review in 10 is a 1-star. At 4.9 stars, it is about 1 in 90. Nine times the complaint rate, half a star apart
- • The middle does not exist. 87% of all reviews are 5-star, 4.5% are 1-star, and just 1.4% are 3-star
- • The bill is the biggest flashpoint: 27.8% of written negative reviews are about feeling overcharged, with rude treatment right behind at 23.6%. The median disputed amount: $436
- • Angry customers write reviews three times longer than happy ones
- • 1 in 6 five-star reviews names a staff member personally
- • Wellington workshops have the lowest complaint rate in the country. Queenstown has three times Wellington's rate
- • Nearly a third of NZ workshops have never claimed their Google listing, and effectively never reply to a review
The rating cliff: what half a star really means
Google shows customers a single number. Here is what that number contains. We took every workshop with at least 10 reviews and measured what share of its reviews are 1-star, band by band:
| Google rating | Workshops | Reviews | Share that are 1-star |
|---|---|---|---|
| Below 4.0 | 45 | 1,924 | 29.5% |
| 4.0 to 4.2 | 49 | 4,018 | 18.3% |
| 4.2 to 4.4 | 107 | 7,548 | 13.2% |
| 4.4 to 4.6 | 197 | 15,684 | 8.6% |
| 4.6 to 4.8 | 410 | 38,121 | 4.8% |
| 4.8 to 4.9 | 292 | 29,882 | 2.6% |
| 4.9 to 5.0 | 484 | 50,863 | 0.8% |
The relationship is a cliff, not a slope. One-star reviews make up 10.5% of everything written about workshops rated around 4.4, and 1.15% at workshops rated around 4.9. Same industry, same country, nine times the complaint rate.
That matters because customers read ratings the same way. A 4.4 looks respectable next to a 4.9 until you realise it means one in every ten customers was angry enough to write about it.
There is no middle ground
Across all 149,248 reviews: 87.1% are 5-star, 4.5% are 1-star, and the entire middle, 2, 3 and 4 stars combined, is just 8.4%. Only 1.4% of customers ever leave a 3-star review.
People review workshops when they are delighted or when they are furious, and almost never in between. Two details from reading thousands of them:
The angry ones write essays. The median 1-star review runs 303 characters; the median 5-star runs 103. A bad experience produces three times the words, forever, on the first page of your Google profile.
And 17% of 1-star reviews have no text at all. No explanation, no story, nothing to respond to. Just a silent star dragging the average down.
Money first, manner right behind
We hand-read and labelled 1,050 one and two-star reviews: an 800-review random sample, then a fresh 250-review sample from different regions to confirm the numbers held (they did). One review can carry more than one theme, and 17% of 1-stars have no text at all, so shares are of negative reviews with written text:
| What 1 and 2-star reviews complain about | Share of written negative reviews |
|---|---|
| Overcharging or feeling ripped off | 27.8% |
| Rude or unprofessional treatment | 23.6% |
| Job not fixed, had to come back | 18.6% |
| Communication failure: no updates, no callbacks | 16.7% |
| Dishonesty | 16.4% |
| Could not get booked in | 7.4% |
| Final bill higher than the quote | 5.3% |
The bill leads, and it is remarkably specific: 28% of negative reviews name an exact dollar figure, and the median disputed amount is $436 (the middle half sit between $158 and $950). These are everyday invoices, not blown engines. Very few negative reviews complain that good work cost fair money; the anger is at feeling ripped off, not at spending.
Treatment is barely behind. Rude or dismissive service turns up in 23.6% of written complaints, and communication going dark, the car ready late with no call, the quote that never arrived, in another 16.7%. For mobile mechanics that communication figure explodes to 43.3%, more than three times the rate at fixed-premises shops: when your workshop is a van, your phone is your front desk.
The 5-star side is the mirror image. The most common praise themes are speed (17.6% mention fast turnaround or same-day service), fair pricing (8.5%), and honesty (7.2%). And 16.9% of five-star reviews name a specific person: the mechanic who explained the fault, the person at the desk who squeezed them in. Customers do not thank companies. They thank Dave.
Where the happy customers live
Complaint rates are not evenly spread. General mechanic workshops, ranked by region:
| Region | Reviews analysed | Average rating | 1-star share |
|---|---|---|---|
| Wellington | 7,915 | 4.82 | 2.9% |
| Manawatu-Whanganui | 2,391 | 4.74 | 3.4% |
| Rotorua / Taupo | 1,404 | 4.70 | 4.3% |
| Taranaki | 1,072 | 4.66 | 4.9% |
| Hawke's Bay | 1,766 | 4.66 | 5.0% |
| Canterbury | 8,039 | 4.68 | 5.3% |
| Northland | 1,797 | 4.63 | 5.5% |
| Waikato | 4,451 | 4.64 | 5.8% |
| Bay of Plenty | 3,303 | 4.64 | 5.8% |
| Auckland | 25,671 | 4.66 | 5.9% |
| Otago | 1,287 | 4.62 | 5.9% |
| Southland | 745 | 4.57 | 6.0% |
| Nelson / Tasman / Marlborough | 1,230 | 4.63 | 6.3% |
| Queenstown / Central Otago | 1,129 | 4.53 | 8.6% |
Wellington is the standout: the highest average rating in the country (4.82) and a complaint rate under 3%. Queenstown and Central Otago sit at the other end with 8.6%, three times Wellington's rate. We suspect tourist-town dynamics play a part, one-off customers, urgent jobs, no relationship to protect, but the data does not tell us why, only that the gap is real.
By trade, tyre shops are the best-reviewed vertical (3.3% one-star share), mobile mechanics sit at 4.6%, and general mechanics and auto electricians share the highest complaint rate at 5.3%.
The unclaimed third
29.6% of the general mechanic workshops we found have never claimed their free Google Business Profile. The difference shows:
Unclaimed shops average 15 reviews; claimed shops average 76. Unclaimed shops average a 4.51 rating against 4.66 for claimed. And because you cannot reply to reviews on a listing you have not claimed, they respond to almost nothing: in our sample, owners at claimed shops replied to 39% of reviews. At unclaimed shops, 0.2%.
Even claimed shops have a blind spot. Across 17,694 reviews we checked reply data for, owners answered 36.6% of five-star reviews but only 32.3% of one-stars: more energy thanking fans than answering the angriest customers. And the lukewarm middle gets the least attention of all, which is a shame, because the 3-star reviewer is often the customer still deciding whether to come back.
What to do with all this
Claim your listing today
It is free, takes 20 minutes, and the unclaimed third of the market averages 61 fewer reviews than the shops that bothered. You cannot reply, post photos or fix your details until you do.
Answer the middle, not just the extremes
Everyone firefights 1-stars. Almost nobody answers the 3-star customer, and that is the one still deciding whether to return. A two-line reply beats a lost regular.
Coach the counter, not just the workshop floor
Nearly 1 in 4 written complaints (23.6%) is about how someone was spoken to, and another 16.7% about communication going dark. The person answering the phone shapes your rating as much as the person holding the spanner.
Call before the bill grows
Feeling overcharged is the number one complaint (27.8%), and 28% of angry reviews quote the exact dollar amount, median $436. A clear quote upfront and one phone call before extra work removes most of them, and both are free.
Put names on the work
1 in 6 five-star reviews names a person. Introduce your people, sign job cards, have the mechanic hand the keys back. Customers thank people, not companies.
Ask when the job goes well
87% of reviews are 5-star, but only from customers who were asked or moved to write. Speed, fairness and honesty are what they praise, so ask at the moment you have just delivered one of those.
One more number worth knowing: 6.3% of every written review in the country mentions a WoF. The warrant visit is still the single most reviewable moment a workshop has, which is worth thinking about before the 2026 WoF changes stretch inspection gaps to two years. We have covered what that does to workshop revenue and how to keep customers through the change.
Your rating is a system, not luck
