Marketing agency or AI? What NZ businesses pay in 2027
Agency retainers often cost thousands a month. Here’s which of that work AI can draft for under NZ$30, and when an agency still earns its fee.
What agencies charge in New Zealand
| Service | Typical NZ price | Source |
|---|---|---|
| Full-service retainer (SEO, ads, web, strategy) | NZ$3,000 to NZ$7,000 a month, plus GST | 1 |
| Social media management | NZ$1,000 to NZ$3,000 a month plus ad spend; other quotes from NZ$500 to NZ$5,000 | 1, 2 |
| SEO retainer | NZ$1,500 to NZ$4,000 a month | 1, 2 |
| Blog writing | NZ$200 to NZ$500 or more a post | 2 |
At NZ$1,500 a month, a basic retainer is NZ$18,000 a year. JENA’s Starter plan for a year is NZ$348.
Your agency is probably using AI too
Many agencies now draft with the same AI tools you can use yourself. In a Databox and Jasper survey of 255 marketing and advertising agencies, about 88% said they use generative AI for written content such as blogs4. In a small survey of agencies at the end of 2025, more than three-quarters planned to use AI in 20265.
That isn’t wrong in itself: a good agency uses AI to work faster and spends the saved time on strategy. But if most of what you receive each month is AI-drafted posts and blogs, you’re paying agency rates for work an AI tool can draft for you directly. Ask your agency two questions:
- How much of my monthly content is drafted by AI?
- What do you add on top: strategy, testing, design, results?
If the answer to the second question is “not much”, that’s the part of the fee you can stop paying.
What AI can now do for under NZ$30 a month
- Social posts for Facebook and Instagram, written from your own photos and jobs.
- Blog posts and web pages that answer your customers’ questions.
- Email newsletters and offers.
- Replies to reviews and enquiries.
- Simple designs: post images, flyers and ads from your brand kit.
The catch is that someone still has to check it. AI can get a price, a date or a claim wrong, and Fair Trading Act rules apply to your ads whoever writes them.
Two ways to do it
A general AI assistant, such as Claude or ChatGPT. You ask, it drafts, you copy, check and post. Claude Pro is US$20 a month, or US$17 a month on a yearly plan3. Good if you have the time to brief it each time.
AI employees, such as JENA. You give a Marketing Manager, Content Writer or Social Media Manager a role and your business details once. It drafts the week’s posts and pages and asks for your approval before anything is sent or posted on your behalf. NZ$29, NZ$99 or NZ$299 a month, GST included, with a 7-day free trial. Full disclosure: NOVA makes JENA.
When an agency is still worth it
- You spend thousands a month on ads and need someone managing and testing them daily.
- You need a brand built from scratch, a video shoot or a website rebuild.
- Nobody in the business has the time or interest to check and approve marketing each week.
Many small businesses do well with a mix: AI for the weekly routine, and an expert paid by the project for the big pieces.
How to decide
- List what your agency actually delivers each month: posts, pages, reports, ads.
- Price each item at the rates above.
- Try AI on the routine items for a month, with approvals on.
- Keep paying for the parts AI didn’t do well.
