$20 a day is up to $608 a month of Google Ads spend. In a single Bay of Plenty trade niche that is usually enough to test one service properly and pull in one to three enquiries a week. Spread across five services and three towns, it buys nothing you can learn from.
One thing to get straight first. The daily budget is not a hard daily cap. Google can spend up to twice it on a busy day and pull back on a quiet one, and it will not bill you more than your daily budget times 30.4 in a month (Google’s daily budget policy, as at July 2026). So $20 a day is $608 a month at the top end, not $600, and some individual days will read $38.
Is $10 a day good for Google Ads?
For most New Zealand service businesses, no. $10 a day is about $304 a month. At the $4 to $9 a click we typically see on trade searches in the Bay of Plenty, that is one to three clicks a day and roughly 40 to 70 clicks a month. If eight per cent of those clicks enquire, you get three to six enquiries a month, and you need two or three months of that before the numbers mean anything.
The problem is not the money. The problem is time. Google’s bidding needs conversions to work out which auctions are worth entering, and at three enquiries a month it is guessing for a very long while.
A budget too small to gather data is not a cheap test, it is a slow one.
There is one case where $10 a day genuinely works. One town, one urgent high-margin service, ten to twenty keywords in exact and phrase match, and ads only running in the hours you actually answer the phone. Blocked drains, lockouts, hot water cylinder failures. Urgency converts at a much higher rate than research traffic, so you need fewer clicks to learn something.
Here is what each budget level buys, in NZD, at $5 a click and an eight per cent enquiry rate.
| Daily budget | Monthly ad spend | Clicks a month | Enquiries a month |
|---|---|---|---|
| $10 | $304 | About 60 | 4 to 5 |
| $20 | $608 | About 120 | 9 to 10 |
| $30 | $912 | About 180 | 14 to 15 |
| $50 | $1,520 | About 300 | 24 |
What $20 a day actually buys in a Tauranga trade niche
About 120 clicks a month, which is one campaign, one service and one town. That is the whole answer. The mistake we see most often is a $600 budget split across plumbing, drainage, gasfitting and hot water, targeting Tauranga, Papamoa, Te Puke and Katikati. Each of those combinations gets about eight clicks a month, which is not a test of anything.
Click costs vary a lot by what people are searching for. These are the ranges we typically see in Bay of Plenty service accounts, not a published benchmark, so treat them as a starting point rather than a promise.
| Search type | Click cost we typically see | Clicks on $20 a day | What it realistically covers |
|---|---|---|---|
| Urgent job (“blocked drain tauranga”) | $6 to $12 | 50 to 100 a month | One service, one town |
| Standard trade service (“electrician tauranga”) | $4 to $8 | 75 to 150 a month | One service across Tauranga |
| High value project (“bathroom renovation tauranga”) | $8 to $15 | 40 to 75 a month | One service, tight radius |
| Broad or vague (“plumber near me”) | $3 to $6 | 100 to 200 a month | Very little without heavy negatives |
The good news for anyone doing Google Ads in Tauranga is that the auctions here are far less crowded than Auckland or Wellington. A local operator can hold the top of the page on high-intent searches for money that would not get you seen in a main centre. That is exactly why $20 a day can work here and would be pointless in a bigger market.
To make it work on that budget, cut hard:
- One campaign, one service, the service you most want more of.
- Ten to twenty keywords in exact and phrase match. No broad match on a small budget.
- A negative keyword list from day one, covering “jobs”, “salary”, “DIY”, “course”, “free” and every service you do not offer.
- Ad scheduling set to the hours someone will answer the phone.
- One landing page that names the service and the town, with the phone number above the fold.
The minimum spend that makes sense by industry
For most New Zealand service businesses the honest floor is $900 to $1,500 a month in ad spend, which is roughly $30 to $50 a day. Below that you can still run ads, you just have to narrow the target until the budget is enough to matter inside it.
| Industry | Starting ad spend we recommend | Why that number |
|---|---|---|
| Emergency plumbing and drainage | $900 to $1,200 | Clicks cost more, but urgency converts and the job value carries it |
| Residential electrical | $900 to $1,500 | Steady demand, plenty of competitors bidding, needs volume to sort them out |
| Building and renovation | $1,200 to $2,000 | Expensive clicks and a long sales cycle, but one job pays for months |
| Exterior cleaning and housewash | $600 to $900 | Cheap clicks and a low ticket, so it works at the bottom of the range |
| Landscaping and paving | $900 to $1,500 | Seasonal, and quote-heavy, so you need enough enquiries to be picky |
Do not pick a number because it feels comfortable. Work it backwards from your job value. Say your average job is $450 and you keep $180 of that after materials and time. If you win one enquiry in three, that job cost you three enquiries, so three enquiries have to cost less than $180, which means an enquiry has to land under $60. At $5 a click and an eight per cent enquiry rate, an enquiry costs you about $63. That job is marginal on Google Ads. A $2,500 job is not even close to marginal.

Does paying for Google Ads really work?
Yes, when three things are true at the same time. Conversion tracking is set up so you can see cost per enquiry. The ad points at a page built to convert that specific service. And the budget is large enough to gather data inside the target you have chosen. Break any one of those and Google Ads becomes an expensive way to buy traffic.
It fails often, and the reasons are boringly consistent. In audits we see accounts with no conversion tracking at all, so nobody can tell whether it works. We see broad match keywords with no negative list, paying for “plumbing apprenticeships” and “how to fix a tap”. We see ads pointing at a homepage. And we see phones that ring out at 4pm.
The clearest proof we have of the tracking-first order is Rideshare Consultants. We set up end-to-end tracking through Google Tag Manager before touching the budget, then rebuilt the Google and Meta campaigns around conversion objectives. That produced 200+ website leads at a $12 average cost and 250 Facebook lead-form leads at $11, with about a 20 per cent lead-to-client rate. Two honest caveats: that is a financial services client, not a trade, and the cheapest leads came off the Facebook side, not Google. The transferable part is the order of operations.
If you already run ads and you cannot tell me your cost per enquiry off the top of your head, that is the thing to fix before the budget. Send it through and I will look at it as a free Google Ads audit.
What does it cost to have someone manage it on top?
NZ agencies and freelancers typically charge $500 to $1,500 a month + GST to manage a local service account, depending on how many services and towns are involved. That fee should sit on top of your ad spend, not inside it, so a realistic all-in figure for a local service business runs somewhere from about $1,400 to $3,000 a month. We do not publish a rate card, because the work is not the same on one service in one town as it is on six across four suburbs. Book a free 15-minute call and you will get a straight number.
Which leads to the blunt version of the answer. If $20 a day is your ceiling, do not pay anyone to manage it. Handing half of a $600 budget to a manager leaves $300 of clicks, and $300 of clicks cannot produce enough data for anyone to manage. Run it yourself on one service and one town, or put the money into following up the customers you already have, which is usually cheaper per job anyway.
When your ad budget gets to $900 to $1,500 a month, management starts paying for itself in wasted spend alone. Before that, keep it simple and keep it narrow.
If you are not sure which side of that line you sit on, book a 15-minute call or send me your account. I will tell you straight whether $20 a day is worth starting on, what to narrow it to, or whether your money is better spent somewhere else first.
