AI Consultant vs Agency vs IT Firm vs DIY: NZ Comparison

In short

In short: DIY (ChatGPT or Copilot seats, Zapier, Make) is right when the job is simple and you have someone with the time. An independent consultant is right for one or two defined processes where you want to deal directly with the person building it, and can live with one person's capacity. An agency is right for a bigger build that needs several skills at once and cover when people are away. A big IT firm or consultancy is right when the work spans the whole organisation and needs formal governance, procurement and long-term support. Whoever you pick, get a fixed price for builds, own the code and accounts, and see something they built that is still running.

The short answer

Match the provider to the size and shape of the job, not to the size of your business. Many "best AI consultant in NZ" lists are written by firms that appear on them, and this page is written by one too, so I've tried to say plainly where each option beats mine.

	DIY tools	Independent consultant	Agency	Big IT firm or consultancy
Best for	Simple hand-offs, personal productivity	One or two defined processes	A larger build needing several skills	Organisation-wide programmes
Who you deal with	Yourself	The person building it	Usually an account or project manager	A partner, a project team and often a separate build team
Speed to first result	Hours to days	Days to weeks	Weeks	Months
Cover when someone's away	Whoever set it up	The weak spot. Ask about it	Good	Good
Watch out for	Quiet failures nobody notices	Capacity, and what happens if they leave	Juniors doing the work you were sold by seniors	Strategy that someone else has to build

DIY tools

DIY is the right answer more often than consultants like to admit. If the job is "when this happens, do that" between popular apps, Zapier, Make or Power Automate will do it, and someone in the office can set it up in an afternoon. As of October 2026, Make starts at about NZ$16 a month and Zapier at about NZ$35, and staff seats for ChatGPT, Claude or Copilot run roughly NZ$30 to $45 a person a month.

Good: Cheapest to start, fastest to try, and nobody else needs to understand your business.
Not so good: The person who built it is now the only one who understands it, failures can be silent, and the bill grows with volume.
Right when: The input is the same shape every time, nothing needs reading or judging, and a failed afternoon costs nothing.

There's a detailed comparison in Make vs Zapier vs a custom build.

An independent consultant

An independent consultant is one experienced person, sometimes with a contractor or two, who both advises and builds. That's what I am, so here's the honest version.

Good: You talk to the person writing the code, decisions are fast, and you're not paying for account managers. Prices tend to be lower for the same work.
Not so good: One person can be sick, on holiday or flat out on someone else's project. Nobody solo can honestly promise 24/7 support.
Right when: You have one or two processes that hurt, you want them fixed properly, and you'd rather explain your business once to the person who builds it.

The question to put to any independent: what happens when you're away? A good answer covers alerts that fire without anyone watching, documentation another developer could follow, and code and accounts already in your name.

An agency

An agency brings a team: designers, developers, a project manager, and someone to cover when the lead is away.

Good: Capacity, a range of skills under one contract, and continuity if a person leaves.
Not so good: More layers between you and the builder, more overhead in the price, and the senior people who pitched may not be the ones doing the work.
Right when: The build is big enough to need several skills at once, like a customer app with design, mobile and integrations, or you need guaranteed cover.

Ask to meet the person who will actually build it, and ask whether the AI work is done in-house or passed to a subcontractor.

A big IT firm or consultancy

Large consultancies and IT providers are built for organisation-wide change, and they're very good at it. This group also covers managed IT providers and Microsoft partners, who are the obvious choice when the answer is Copilot and your Microsoft 365 set-up.

Good: Governance, security reviews, procurement paperwork, long-term support contracts, and the weight to deal with large vendors.
Not so good: Slower and dearer for a single process, and the strategy is sometimes handed to a different team or firm to build.
Right when: The work touches many departments, the board or a regulator needs formal sign-off, or you need a team supporting it for years.

If you already have an IT provider, they and a specialist builder can work together. The IT provider looks after devices, accounts and security. The builder delivers the automation into accounts you own. That split works well and nobody's toes get trodden on.

Questions that work for all four

Whoever you're considering, five questions make their quotes comparable.

What's the price, and is it fixed? A build should have a price in writing before work starts. Hourly is fine for small jobs and advice.
What will it cost each month after? Hosting, support, licences and AI usage, all in one number.
Who owns it? The code, the data and the accounts should be yours, documented well enough that someone else could take over.
Where will the data live? A named country and provider, and a plain answer on whether anything trains a public model.
Can I see something you built that's still running? A live system or a client who'll take your call beats any slide deck.

And one more: has anyone measured the process before quoting? If a provider hasn't looked at how the work is done today, benchmarked it and agreed what success looks like, they're guessing. There's a fuller checklist in how to check an AI consultant is legit.

When I'm the wrong choice

I'm not the right fit for every job, and it's quicker to say so here than on a call.

You need someone on call around the clock. I support systems during New Zealand business hours. Use an agency or a managed provider.
It's a company-wide change programme across hundreds of staff with formal procurement. Use a big firm.
A Zap would do it. Set it up yourself, and keep the money.

Where I fit is the space in between: a small or medium business with a process that hurts, which needs more than a no-code tool and less than a programme of work. Builds are a fixed price after free discovery. As of October 2026 most first projects land between NZ$500 and $15,000 excluding GST, with support from NZ$99 a month. The full ranges are on the pricing page.

Frequently asked questions

Is an agency safer than an independent AI consultant?

Safer on capacity, not necessarily on quality. An agency has more people, so holidays and sickness are covered, but there may be an account manager and a project manager between you and the builder. With an independent consultant you deal with the person doing the work; the risk is that one person can only do so much. Either way, ask what happens when the person you're dealing with is away.

Are big IT firms worth it for a small business?

Usually not for a first AI project. Large firms are built for organisation-wide programmes with procurement, governance and long contracts, and they price accordingly. They earn their fee when the work touches many departments, needs formal risk sign-off, or has to be supported by a team for years.

Can I do AI automation myself?

Often, yes. For simple hand-offs between popular apps, Zapier, Make or Power Automate are cheap and you can set them up yourself. Staff seats for ChatGPT, Claude or Copilot cost roughly NZ$30 to $45 a person a month as of October 2026. DIY gets hard when the work needs reading messy documents, high volume, testing against real data, or an audit trail.

We already have an IT provider. Do we need someone else for AI?

Not always. If the answer is Copilot and your Microsoft 365 set-up, your IT provider is the natural choice. If the job needs something built across Xero, a job system and your inbox, a builder who does that every day may be faster. The two can work together: the IT provider looks after devices, accounts and security, and the builder delivers the automation into accounts you own.

How should I compare quotes from different types of provider?

Compare what you'll own and what it will cost to run, not just the build price. Ask each for a fixed price against a written scope, the monthly running cost, who owns the code and accounts, where the data will live, and a system they built that is still running. Quotes that answer those five are comparable. Ones that don't, aren't.

Not sure which one you need?
