How Much Does a Home Builder Marketing Agency Cost in NZ and Australia?
Most residential builders in Australia pay a marketing agency between AUD $2,500 and $6,000 a month for a multi-channel retainer. In New Zealand the typical band is NZD $1,500 to $4,000 a month. That's the fee only. Ad spend sits on top, usually another $1,500 to $5,000 a month in Australia and $800 to $3,000 in New Zealand for a local building company. Help with a single channel, such as Google Ads only or SEO only, starts at around $600 a month. A fully outsourced marketing team starts at roughly $4,000 in NZ and $8,000 in Australia, and goes up from there.
Two common setups (illustrative, not quotes):
- A regional Australian builder turning over around $2M, running Google Ads and SEO with a mid-tier agency: about AUD $3,500 a month in fees plus $2,500 in ad spend, so $6,000 a month all in.
- A New Zealand renovation builder running Google Ads only with a specialist: about NZD $900 a month in management plus $1,500 in ad spend, so $2,400 a month all in.
Our view: the retainer is the wrong number to judge an agency on. What matters is what it costs to win one signed job, with fees, ad spend and your own team's time included. The rest of this guide breaks down each line item, explains why ad spend is billed separately, covers the time cost most builders forget, and shows you how to work out what your business should spend. For the bigger picture on how a builder's marketing system fits together, see how it works.
What you're actually paying for
Agencies bundle services differently, which is why two quotes for "marketing" can be $3,000 apart and still not cover the same work. Break any quote into line items and it gets much easier to compare.
| Line item | Australia (AUD/month) | New Zealand (NZD/month) | What it should cover |
|---|---|---|---|
| Strategy or consulting only | $2,000 to $5,000 | $2,000 to $5,000 | Plan, priorities, channel mix, coaching your team to run it |
| Google Ads management | $800 to $3,000, or 10 to 20% of spend | $600 to $2,000, or 10 to 20% of spend | Setup, keywords, negatives, bids, conversion tracking, reporting |
| Meta (Facebook and Instagram) ads management | $800 to $3,500 | $500 to $1,500 | Campaigns, audiences, creative testing, lead forms |
| SEO and content | $1,500 to $4,000 | $1,000 to $3,000 | Technical fixes, service and suburb pages, articles, Google Business Profile |
| Website build (one-off project) | $3,000 to $25,000 | $1,500 to $15,000 | Design, build, copy, tracking, enquiry forms |
| CRM, automation and follow-up | Often quoted separately | Often quoted separately | Setup fee plus a software licence; ask exactly what's included |
| Multi-channel retainer | $2,500 to $6,000 | $1,500 to $4,000 | Usually ads plus SEO plus reporting |
| Fully outsourced marketing team | $8,000+ | $4,000 to $10,000+ | Strategy, every channel, content and creative |

Why is Google Ads management sometimes a percentage of spend?
Agencies with bigger accounts often charge 10 to 20% of what you spend with Google, usually with a minimum fee. It scales with the workload, but it also means the fee rises every time the budget does. A flat fee is easier to budget and keeps the conversation on results rather than spend. Neither model is wrong. Just know which one you're signing and what happens to the fee if you double your budget in spring.
What should SEO include at that price?
At $1,000 to $3,000 a month you should see work shipping every month: technical fixes, new or improved service and suburb pages, articles that answer the questions your clients ask before they call, and Google Business Profile updates. If the monthly report is mostly rankings for phrases nobody searches, ask what actually got published.
Why do website quotes vary so much?
A $2,000 template and a $20,000 custom build are different products. For a builder, the questions that matter are whether the site loads fast on a phone, shows real projects, makes it obvious how to enquire, and tracks every form and call. A beautiful site that can't tell you where enquiries came from will cost you more over time than a plain one that can.
Where do CRM and follow-up fit?
This is the line item most quotes skip, and it's often where the money leaks. An agency can fill your inbox with enquiries, but if nobody answers the phone for a day, the spend is wasted. Some agencies set up the CRM, automated replies and call tracking. Others hand the enquiry over and stop there. Ask which one you're buying.
Fees vs ad spend: why they're separate
There are two costs in paid advertising, and they go to different places. Ad spend is what Google or Meta charges for clicks and impressions. The management fee is what you pay the agency to plan, build, run and improve the campaigns.
Keep them separate for three reasons.
First, you can see exactly how much reaches the platform. When the two numbers are blended into one invoice, you can't tell whether a $5,000 month bought $4,000 of clicks or $2,000.
Second, you should own the ad account. It should be billed to your card and registered in your business's name, with the agency given access. If you part ways, the account history, the conversion data and years of learning stay with you.
Third, it lets you judge the agency on the right thing. The fee pays for decisions. The spend pays for traffic. Mixing them up makes it hard to tell whether a bad month was a strategy problem or a budget problem.
"Ad spend buys attention. The fee buys judgement. If you can't see both numbers, you can't judge either one."
What does ad spend look like for a builder? Construction clicks are expensive, because one signed job is worth tens of thousands of dollars to whoever wins it. Our Marketing Budget Calculator works on a typical $100 to $250 per enquiry for AU and NZ paid search in building. Across the published 2026 guides, most agencies suggest at least $1,500 a month in Australian ad spend before a campaign gathers enough data to optimise. New Zealand builders tend to start a little lower, in the $800 to $2,000 range.
Is ad spend ever included in the fee?
Sometimes, especially in "all-in" packages aimed at trades. It isn't wrong, but ask for the split in writing. If a package costs $2,000 a month "including ads", find out how much of that reaches Google. At $150 per enquiry, the difference between $500 and $1,200 of real spend is the difference between three enquiries and eight.
The hidden cost: your team's time
No agency quote includes the hours your business puts in, and that's usually the biggest cost of all.
A marketing agency needs things from you every month: project photos, sign-off on ads and pages, answers about which jobs you want more of, feedback on lead quality. Someone on your side has to provide all of that. In most building companies, it's the owner.
Then there's what happens after the enquiry arrives. When we checked the numbers for one builder we work with (ads running, healthy job values), the average first response to a new lead was 19.1 hours, with only 1.6 attempts before follow-up stopped (full breakdown here). A homeowner who enquires on Saturday morning and hears back on Sunday afternoon has usually already spoken to someone else.
When you work out total cost, count:
- Owner hours spent briefing, approving and reviewing reports
- Office or estimator time answering, qualifying and following up enquiries
- Site visit and quoting time for enquiries that were never a good fit
- Delay cost: the jobs you lose because nobody called back the same day
"An agency can double your enquiries. If your follow-up stays the same, you've doubled the number of people who never hear back."
This is also why the comparison with hiring in-house isn't as simple as it looks. A senior in-house marketer in AU or NZ typically costs $70,000 to $120,000 a year before tools and ad spend. That's one person, who still needs the owner's time and still can't cover strategy, ads, SEO, web and CRM equally well.
Agency, consultant or in-house: how the costs compare
| Option | Typical cost | What you get | Who does the work |
|---|---|---|---|
| Freelancer, single channel | Around $500 to $1,500/month | One channel, usually ads or local SEO | Freelancer, with you filling the gaps |
| Consulting or coaching | $2,000 to $5,000/month | Strategy and accountability | Your team does the doing |
| Done-for-you agency | $3,000 to $8,000/month, plus $2,000 to $5,000 ad spend | Strategy and delivery across channels | The agency, with your inputs |
| Senior in-house hire | $70,000 to $120,000/year, plus tools and spend | One dedicated person | Your employee |

The right answer depends on who in your business has time and skill to execute. If you've got a capable office manager and the owner wants to stay close to it, consulting can be the better buy. If nobody has the hours, done-for-you usually wins. We cover the trade-offs in more detail in consulting vs done-for-you for home builders.
Cheap vs expensive: what actually changes
The gap between a $600 package and a $6,000 retainer isn't only about hours. It's about how much of the enquiry-to-contract process the agency takes responsibility for.
What does the low end usually buy?
Under about $1,000 a month you're generally paying for one channel, done with a set template. That can be exactly right for a small builder in a quiet market who just needs the phone to ring more often. Pricing guides in both countries treat anything under about $500 a month as a warning sign, because it rarely covers much skilled human time.
What changes in the middle?
In the $2,000 to $5,000 band you should get a real plan, more than one channel, conversion tracking that separates calls from forms, content written about your actual services and areas, and reporting that talks about enquiries rather than impressions. This is where most established residential builders end up.
What does the top end add?
Above $6,000 or so, you're paying for depth: senior strategists, more content, creative production, and often the systems behind the marketing, such as CRM setup, automated follow-up and call handling. For a builder doing $3M or more, that last part is often worth more than any single ad campaign.
"Cheap marketing isn't the problem. Paying for marketing that stops at the enquiry form is."
Red flags in any agency quote, at any price
- Guaranteed lead numbers or guaranteed Google rankings. Nobody controls the algorithm.
- The agency owns your ad account, website or domain.
- Ad spend and fees are blended with no split.
- Reports about clicks and impressions, with no link to enquiries or signed jobs.
- Minimum terms and exit clauses that aren't spelled out before you sign.
How to work out what you should spend
Start with what a signed job is worth to you, not with what the agency charges. Then work backwards.
Step 1: Gross profit per job. Take your average contract value and multiply it by your gross margin. Residential builders commonly land between 20 and 25%.
Step 2: Enquiries needed per job. If you sign roughly 1 in 10 genuine enquiries, you need 10 enquiries per job.
Step 3: Cost per enquiry. For AU and NZ building, paid search typically lands around $100 to $250 per enquiry.
Step 4: Add the fees and your time. Spread the monthly fee over the jobs you sign in a typical month.
A worked example (illustrative only):
| Input | Figure |
|---|---|
| Average contract value | $600,000 |
| Gross margin (20%) | $120,000 gross profit per job |
| Enquiries per signed job (10% close rate) | 10 |
| Cost per enquiry | $150 |
| Ad spend per signed job | $1,500 |
| Agency fee per month | $3,500 |
| Jobs signed from marketing per month | 1 |
| Total marketing cost per signed job | $5,000 (about 4% of that job's gross profit) |
Change the inputs and the answer moves quickly. Halve your close rate and ad spend per job doubles. Double your cost per enquiry and the same happens. This is why builders who fix their follow-up often get more out of the same budget than builders who move to a pricier agency.
Want to run your own numbers? Use the Marketing Budget Calculator to estimate enquiry spend from your project values, close rate and margin. Add agency fees and your team's time separately to work out the full cost.
Should I set my budget as a percentage of revenue?
It's a reasonable place to start, but it can mislead. Two builders on the same revenue can have very different margins, contract sizes and capacity. Budget from the number of jobs you need to win and what each one is worth, then check the result against revenue as a sense check.
What if I can't take on more work?
Then don't buy more enquiries. Spend on better enquiries: better-fit projects, higher-value work, or a quieter season you want filled. Marketing that fills a calendar you can't build for just creates quoting work that goes nowhere.
Questions to ask before you sign
Put these to every agency you're considering. How they answer tells you as much as the numbers.
- What exactly is included each month? Ask for deliverables, not activities.
- How much of my budget goes to ad spend, and how much to fees? Get it in writing.
- Who owns the ad accounts, website, domain and data? It should be you.
- How do you track enquiries back to a channel? Calls, forms and walk-ins should all be counted.
- What happens after the enquiry arrives? Do they touch follow-up, CRM or call handling, or does it stop at the form?
- What do you need from me each month, and how many hours will it take?
- What's the minimum term and the exit process? Get it clear before you sign, whatever it is.
- What does the report show? You want enquiries, quotes and signed jobs, not just traffic.
- Who does the work day to day? Will it be the person who sold you the deal, a junior, or an offshore team?
- Have you worked with residential builders before? Construction lead times, seasonality and job values are different from most industries.
FAQs
How much should a builder spend on marketing?
Work it out from the jobs you need and what each one is worth, rather than picking a flat figure. For most established residential builders in AU and NZ, fees plus ad spend land somewhere between $2,500 and $10,000 a month. The Marketing Budget Calculator gives you a figure based on your own margin and contract size.
Is ad spend included in agency fees?
Usually not. Most agencies bill management separately, and your ad spend goes directly to Google or Meta. Where a package says "ads included", ask for the split so you know what actually reaches the platform.
What's a normal marketing retainer for a builder?
In Australia, multi-channel retainers commonly run AUD $2,500 to $6,000 a month. In New Zealand, NZD $1,500 to $4,000 is typical. Single-channel help starts at around $600, and fully outsourced teams go well above these ranges.
Is it cheaper to hire someone in-house?
On paper, sometimes. A senior hire costs $70,000 to $120,000 a year plus tools and ad spend, and still depends on the owner's time. One person rarely covers strategy, ads, SEO, web and follow-up equally well, so builders often end up paying for help on top of the hire anyway.
How long before I know if an agency is working?
Paid ads produce data within weeks, and most campaigns settle after 8 to 12 weeks of optimisation. SEO usually takes 3 to 6 months to show meaningful movement. Judge progress on enquiry quality and quotes issued, not just traffic.
What should a builder get for the money?
A clear plan, tracking that ties enquiries to their source, work shipped every month, and reporting in plain English about enquiries, quotes and signed jobs. At the higher end, you should also get help with what happens after the enquiry, because that's where most builders lose jobs.
Where to start
Before you compare agency quotes, find out where your current marketing is losing money. It might be the ads, the website, or the hours between an enquiry and a callback. The answer changes what you should be buying.
The Builder Growth Assessment takes about two minutes and pinpoints the system to fix first, whether that's lead flow, follow-up, delivery or owner dependency. Take it before you sign anything. If you'd like to see how the pieces connect, the Builder OS sets out the full system, or for general enquiries, get in touch. More on who we work with is on the Contractor Scale homepage.
