How much does a marketing agency cost in NZ?

01What does a marketing agency cost in New Zealand in 2026?

A New Zealand marketing agency in 2026 bills NZD 95 to 200 an hour, or a monthly retainer that grows with the number of channels it runs. One channel costs about NZD 500 to 1,500 a month, several channels NZD 1,500 to 4,000, and a full-service retainer NZD 4,000 to 10,000 or more, before GST and ad spend.

Those bands come from Jelly Digital's September 2026 NZ pricing guide, which puts agency hourly rates at NZD 95 to 200 and multi-channel retainers at NZD 1,500 to 4,000 a month¹. A second Auckland agency lands in a similar place: King Tide Marketing's July 2026 guide prices one channel done properly at NZD 1,000 to 2,000 a month and genuine multi-channel work from NZD 5,000². Both are agencies estimating their own market, so read them as a range and check them against the published price pages further down.

Very little of this is public. Digital Nomads HQ audited 411 service lines across 140 Australian agencies in June 2026 and found 78% published no pricing at all³. Expect to ask for a quote, and expect it to arrive in a format that is hard to set beside the next one. That is why the last half of this guide is about comparing quotes. The wider guide to AI marketing costs in Australia and New Zealand puts agencies next to tools, freelancers and hires.

02What does a marketing retainer buy?

A marketing retainer is a fixed monthly fee paid to an agency or freelancer for an agreed scope of ongoing work, such as SEO, social media or paid ads management. The fee buys a block of people's time. Divide it by the agency's hourly rate and you get the hours you can expect each month.

The arithmetic is worth doing before any meeting. At NZD 95 to 200 an hour, a NZD 1,500 retainer buys between about 7.5 and 16 hours a month. A NZD 4,000 retainer buys about 20 to 42 hours. Account management, meetings and reporting come out of those hours before anyone writes a post or adjusts a campaign.

A small retainer spread over many channels gets thin quickly. Ten hours a month split across three channels is about three hours each, enough to keep something running and rarely enough to build it. That is the logic behind King Tide's advice to put a modest budget into one channel and do it properly. The glossary has a short entry for marketing retainer if you need the term for a board paper or a quote comparison.

03Marketing agency prices by service

Priced by service, New Zealand agencies charge about NZD 500 to 3,000 a month for SEO, NZD 500 to 2,000 for social media, and NZD 300 to 1,500 to manage Google Ads, or 10 to 20% of the ad spend. One-off work such as a website or a brand identity is quoted as a project, from about NZD 1,500.

Published price pages give the clearest picture, because the number is on the page. As of October 2026, Clickthrough lists SEO packages at NZD 960, NZD 1,460 and from NZD 2,460 a month plus GST⁴, The SEO Guy lists retainers at NZD 795 a month on a six-month minimum and NZD 1,495 a month⁵, and OnlineNZ lists SEO programmes from NZD 499 to 1,999 a month and social management from NZD 149 a month, on one month's notice⁶.

The spread inside one service is wide because the work differs. Clickthrough's entry package covers 5 to 10 pages; a package four times the price should cover far more of the site, plus new content and technical fixes. Ask for the page count and the monthly deliverables in writing, then compare like with like.

04What you get at each price tier

Each price tier buys a different shape of work. Under NZD 1,500 a month you get one channel kept running. NZD 1,500 to 4,000 buys one main channel built properly with support on a second. Above NZD 4,000, an agency can coordinate several channels and tie its reporting to enquiries and sales.

The middle band is where King Tide's own guide puts "primary channel plus support" at NZD 2,000 to 4,000 a month. Before you sign at any tier, ask what the first 90 days produce. A sensible answer names deliverables, such as pages built and tracking installed, and one number that should move. Agencies rarely promise outcomes, and that is reasonable. What you can hold them to is the work and the reporting.

05Which costs sit outside the agency retainer?

The retainer is rarely the whole bill. Ad spend is paid on top, often with a minimum. Setup or onboarding fees are common, quotes usually exclude GST, and software the agency uses may be passed on to you. Your own time counts too: someone in the business has to brief, approve and supply material every month.

The Australian audit puts numbers on this. Digital Nomads HQ found ads setup fees of AUD 499 to 1,999, onboarding fees from AUD 550, and 22% of agencies disclosing a minimum ad spend of AUD 500 to 15,000 or more a month³. The same audit found 78% of listed prices exclude GST. In New Zealand, a business that is not GST registered should add 15% to any plus-GST price, because it cannot claim the GST back.

• Ad spend, the money paid to Google or Meta. A fee of 10 to 20% of spend rises as spend rises, so ask for a cap.
• Setup fees for account builds, tracking and audits. Ask whether they are one-off and what you own at the end.
• Minimum terms. A six-month minimum appears on at least one published NZ price page, while others ask a month's notice.
• Tools such as SEO software, schedulers and reporting dashboards. Some agencies include them and some pass them on.
• Your hours for briefing, approving and finding photos. Put an hourly value on them and include it in the comparison.

06How much should a small business spend on marketing?

New Zealand's government guidance leaves the number to you. The business.govt.nz guide lists four ways to set a budget: spend what your objectives need, take a share of sales, match competitors, or spend what feels affordable. For hiring outside help, an Auckland agency puts the sensible floor at NZD 1,000 to 1,500 a month.

The business.govt.nz marketing strategy page, last edited in August 2026, lists those four methods and recommends no percentage⁷. You will see "5 to 10% of revenue" quoted as a rule on agency blogs. This guide could not find it at any primary source for New Zealand small business, so it is left out.

The floor comes from an agency being candid about its own market: King Tide Marketing advises that if you cannot put at least NZD 1,000 to 1,500 a month into marketing, you should not hire anyone². Below that, your own time with good tools, or a freelancer for one defined project, usually goes further. For context on what small firms spend, LocaliQ's December 2025 survey of more than 730 small businesses, mostly in the US and Canada, found 33% had monthly marketing budgets under USD 1,000⁸. That is North American data, so treat it as a rough guide.

The objectives method suits most owners. Decide how many extra enquiries a month you want, estimate what each one is worth, and work back to a budget. That leads straight into the comparison below.

07How to compare agency quotes on cost per enquiry

Cost per enquiry is total marketing spend in a period divided by the number of genuine enquiries it produced. It turns quotes with different scopes into one comparable number. Add the fee, ad spend, tools and a value for your own time, then divide by the enquiries you expect or have measured.

1. Total the monthly cost of each option: fee, ad spend, any setup fee spread over 12 months, tools, and your own hours at an hourly value you choose.
2. Agree what counts as an enquiry: a call, form or booking from a real prospect. Leave out spam and job seekers.
3. Ask each provider for a realistic enquiry estimate, or use your own past numbers for that channel.
4. Divide cost by enquiries, then compare the result with what an enquiry is worth to you: average job value multiplied by the share of enquiries you win.
5. After three months, recalculate with real numbers and keep whichever option wins.

The numbers are made up to show the method. Here the cheaper retainer loses, because it needs more of the owner's time and produces fewer enquiries. Whether NZD 215 is good depends on your margins. If an average job is worth NZD 3,000 and you win one enquiry in four, each enquiry is worth about NZD 750, and both options pay for themselves. The glossary entry on cost per enquiry gives the definition in one line.

08What to ask a marketing agency before you sign

Ask who will do the work, how many hours or deliverables the fee covers each month, what the minimum term and notice period are, and who owns the accounts and content if you leave. Those four answers tell you most of what a proposal leaves vague. Then ask how they report, and on which number.

• Who works on my account each week, and how senior are they?
• What exactly ships each month, in pages, posts, campaigns or hours?
• Are the ad accounts, analytics and website set up in my business's name?
• What are the setup fees, the minimum term and the notice period?
• Is GST included, and are tools or ad spend marked up?
• Which number will your monthly report lead with?
• Can I speak to a current client of a similar size in New Zealand?

Red flags worth walking away from include a guaranteed ranking or a guaranteed number of leads, ad accounts held in the agency's name, reports full of impressions with no line for enquiries, a long lock-in with no exit for missed deliverables, and nobody able to tell you who does the work.

Survey data backs up asking hard questions early. Setup's 2025 Marketing Relationship Survey, a small sample of about 100 mostly US responses, found 61% of clients who ended an agency relationship cited dissatisfaction with value, up from 36% in 2024, and 44% said the agency did not understand their business⁹. The same survey found clients who chose an agency through word of mouth were more often satisfied (82%) than those who found one through search (70%). Ask peers in your industry who they use.

09Where Flow AI fits

Flow AI is an AI marketing transformation practice: the strategy, the systems and the agents that run a marketing function, engineered end to end. A written scope names the first system to build, and each build is priced per project.

On price that sits below a multi-channel retainer, and the trade-off should be clear before you compare. Amber Lan builds and runs the systems herself, so you get one practitioner and AI agents doing the production, with no account team or media-buying department, and ad spend stays separate as it would with any agency. The sprints and the skill library are public, so you can judge what gets installed before you talk to anyone.

10The short version

A New Zealand marketing agency costs NZD 95 to 200 an hour, or a retainer of about NZD 500 to 1,500 a month for one channel, NZD 1,500 to 4,000 for several and NZD 4,000 to 10,000 or more for full service. Add GST, ad spend, setup fees and your own time to reach the real number.

Compare quotes on cost per enquiry, keep your accounts in your own name, and start with one channel done well.
