Claude vs ChatGPT for NZ Business: Which Should You Use?

Short answer: if you want AI that works inside the tools your business already runs - Xero, Outlook or Gmail, your calendar, your job management system - Claude is the better fit for most New Zealand businesses, and it’s what I run my own business on. ChatGPT is the better pick if you need images every day, need your data stored in Australia, or your team already has its workflows built in it. They cost the same, so price shouldn’t decide it.

I’m not neutral: I moved Harkness AI from ChatGPT to Claude, and setting Claude up for NZ businesses is a big part of what I do. So every price and feature below comes from Anthropic’s and OpenAI’s own pages, checked on 26 September 2026, with links so you can check them yourself. All prices are in NZ dollars and include 15% GST.

Is Claude better than ChatGPT for business?

For most NZ businesses that want AI to do actual admin, yes. Claude connects to Xero, Microsoft 365, Google Workspace and custom systems through connectors and MCP (the Model Context Protocol, the standard that lets AI plug into other software), and Skills let it run your processes the same way every time. That’s the difference between an AI you copy and paste into and one that does the work.

ChatGPT is still very good at general chat, research and images, and it’s ahead on data residency for teams that need their data held in Australia. Here’s the full picture.

Claude vs ChatGPT side by side

Sources, all checked 26 September 2026: Claude pricing, ChatGPT Business overview, ChatGPT Pro plans and connected apps in ChatGPT, plus the feature pages linked further down. Both companies change their plans often, so check before you buy.

What can Claude do that ChatGPT can’t?

• Claude Design. You describe a design and Claude builds it: prototypes, slide decks, one-pagers and animations, using your brand’s colours and fonts. You can export to PDF, PowerPoint or HTML, or hand it to Canva, Figma or Claude Code. It launched in April 2026 and is in beta on the Pro, Max, Team and Enterprise plans. ChatGPT has nothing quite like it.
• Excel, PowerPoint and Word add-ins. Claude for Microsoft 365 puts Claude inside Excel, PowerPoint and Word on the paid plans, with Outlook in beta. For businesses that live in spreadsheets, working inside the file beats uploading it to a chat window.
• Skills on every plan. A Skill is a saved set of instructions and files that Claude loads when a job needs it: your proposal format, your invoice rules, your brand voice. Claude has Skills on every plan, including Free. ChatGPT added Skills too, but only on its Business and Enterprise plans.
• Custom connectors on every plan. You can add your own MCP connector on any Claude plan (Free is limited to one). ChatGPT’s equivalent, developer mode, is a beta for Business and Enterprise. This is how I connect clients’ warehouse and job management systems, and how I connect Claude to Blender.
• An official ChatGPT memory import. Claude has an import page built to bring across what ChatGPT knows about you. More on that below.

What can ChatGPT do that Claude can’t?

• Make images. ChatGPT Images is on every plan, with lower limits on Free. Claude doesn’t generate images at all. It can draw charts and diagrams, but not photos or illustrations.
• A cheaper plan. ChatGPT Go works out at about NZ$16 a month. Claude’s cheapest paid plan is Pro at NZ$40.
• More mature voice. Both have voice mode, but Claude’s is still labelled beta. ChatGPT Voice has several modes, about two hours a day on Free and near-unlimited use on paid plans.
• Publish a website from the chat. ChatGPT Sites (public beta on Plus and Pro) turns a conversation into a live web page. With Claude you’d build it with Claude Code or Claude Design and host it yourself.
• Keep data in Australia. ChatGPT Enterprise offers Australian data residency. The Claude app doesn’t (details below).

Two things people still expect from ChatGPT are going away. OpenAI shut Sora down (the app closed in April 2026), so neither tool makes video now. And custom GPTs are being retired: you can’t create new ones after 26 October 2026, and they stop working on 11 December 2026. If your team has built workflows on GPTs, you’re rebuilding them either way.

Which Claude and ChatGPT features are the same thing?

A lot of the confusion comes from both companies naming the same idea differently. Here’s how they line up.

The biggest match is the “do the work for me” agent. Since 16 September, Cowork is built into the main Claude app rather than being a separate mode. ChatGPT Work launched in July 2026 and replaced ChatGPT agent. And Claude in Chrome became generally available on the paid plans in August 2026.

So when someone tells you “ChatGPT can do X”, it’s worth checking whether Claude does the same thing under another name. Usually it does. The real differences are the ones in the two sections above.

How much do Claude and ChatGPT cost in NZ dollars?

The same at every level most businesses buy. One person on Claude Pro or ChatGPT Plus is about NZ$40 a month. For a team, I quote clients about NZ$40 a seat a month for Claude Team, which is the yearly seat price.

Both companies set their prices in US dollars, so these move with the exchange rate. I converted them at the European Central Bank reference rate for 25 September 2026 and added GST. OpenAI offers localised pricing at checkout, so the ChatGPT price you see may differ a little. Every Claude plan is broken down in Claude pricing in NZ dollars, and the Claude plan picker tells you which one fits.

Do Claude and ChatGPT charge GST in New Zealand?

Both list prices before tax, and your billing address decides the tax. Under IRD’s rules for overseas suppliers, a supplier treats a NZ customer as not GST-registered unless the customer says they are or gives their GST number. So if you’re GST-registered, add your GST number in the tax ID field (Claude, ChatGPT) when you sign up, and you won’t be charged the 15%: a NZ$41 plan comes down to about NZ$35. If you don’t, the prices above are what you’ll pay. Check the first invoice, and ask your accountant how to code it - I’m an engineer, not a tax adviser.

Do Claude or ChatGPT train on my business data?

Not by default on the business plans. Claude Team and Enterprise have no model training by default, and OpenAI doesn’t train on Business, Enterprise or Edu data by default. On personal plans it’s the other way round. Claude Free, Pro and Max train on your chats if the model training setting is on, and ChatGPT Free, Plus and Pro have “Improve the model for everyone” switched on until you turn it off.

If staff are putting client or customer information into AI, the Privacy Act 2020 still applies. That’s the main reason I tell every team to pay for Claude Team or ChatGPT Business instead of letting everyone run personal accounts.

Can I keep my business data in Australia?

This is where ChatGPT is ahead. ChatGPT Business lets you choose a storage region at checkout (still rolling out), and Enterprise includes data residency in Australia at no extra cost. Some safety and abuse-monitoring data is still kept in the US either way.

For Claude, Anthropic says data is stored in the US, with processing that may route through the US, Europe, Asia and Australia. Australian regions for Claude exist through AWS Bedrock, Google Vertex and Microsoft Foundry, but that’s a developer and enterprise route, not the Claude app. Most of the NZ small businesses I work with don’t have a residency requirement, but if a contract or client says your data must stay in Australia, that decides it.

Which is better for connecting to Xero and Microsoft 365?

Claude, as of September 2026, and Xero is the clearest example. Xero has an official read-only connector in Claude, free on every plan, so you can ask about profit, cash and overdue invoices from live data. For write work - logging receipts, creating invoices, contacts and bank transactions - Claude runs Xero’s open-source MCP server. I walk through that in how to connect Claude to Xero. ChatGPT has no official Xero app, so it’s developer mode or a third-party connector.

On Microsoft 365, Claude’s connector searches Outlook, Teams, SharePoint and OneDrive on every plan, as long as you have a Microsoft business account (not a personal Outlook.com one). ChatGPT has apps for Outlook, SharePoint, Teams, Gmail and Google Drive too, so for Microsoft and Google alone it’s closer than people think. The gap opens up with the NZ-specific systems: Xero, job management, CRMs, and your own software, where MCP and Claude Code make Claude much easier to wire in.

Which is better for writing, coding and spreadsheets?

• Writing: Claude, in my experience. It’s less of a “yes man”, pushes back when an idea is weak, and its drafts need less editing to sound like a person. That’s my opinion from daily use, not a benchmark.
• Coding: both include a coding agent - Claude Code on Claude’s paid plans, Codex in ChatGPT. I build client tools, MCP servers and this website with Claude Code.
• Files and spreadsheets: both read PDFs and spreadsheets and run code to analyse them. Claude also creates Excel, Word, PowerPoint and PDF files on every plan, and works inside Excel itself on the paid plans.
• Images: ChatGPT, easily. Claude doesn’t generate images at all.
• Voice: both have voice mode on every plan. In my experience ChatGPT’s is the more polished of the two for back-and-forth conversation.

Which should a NZ business pick?

Sole trader

Claude Pro at NZ$40 a month. Connect your email, calendar and Xero, and turn off model training in privacy settings. If you mostly want quick answers and images for social posts, ChatGPT Plus is the same price and does that better, and ChatGPT Go at about NZ$16 is fine for light use.

Team of 5 to 20

Claude Team, billed yearly once you’re sure - about NZ$41 a seat a month. You get central billing, SSO, admin control over which connectors people can use, and no training on your data. Give premium seats only to the one or two heaviest users. Pick ChatGPT Business instead if you need your data stored in Australia, or the team already has its workflows built in ChatGPT.

Accountants and professional services

Claude Team. The Xero connector and the Excel add-in make it the practical choice for accounting firms, and Skills suit the repeatable work - engagement letters, file notes, proposals, client emails in the firm’s voice. Check your client engagement terms on where data can be stored before you choose. If they require Australia, that points to ChatGPT Enterprise.

Trades

Start with whichever one connects to your job management system. ServiceM8 publishes its own MCP server that works with both. For quoting, job notes and chasing invoices in Xero, I’d still pick Claude. Use voice mode on the phone between jobs - it’s faster than typing on site.

How I actually use both

Claude is my daily driver. It’s connected to my Gmail, Google Calendar, Google Drive, Notion and Xero. It drafts my Xero invoices and bills for me to approve, writes client proposals from meeting transcripts, emails and past project notes using a proposal Skill, and I use Claude Code to build client tools and this website. For clients I’ve built read-only MCP connections into a warehouse system and a job management system, so their team can ask questions of live data in Claude.

I still use OpenAI for two things. ChatGPT’s image generation makes my YouTube thumbnails, because Claude can’t make images. And I use OpenAI’s Whisper to transcribe meeting recordings. It isn’t all or nothing. But for a business, I’d pick one as the daily driver and learn it properly rather than half-learning two.

Can I move from ChatGPT to Claude without losing my history?

Yes, and it takes about ten minutes to get going:

1. Export your old ChatGPT chats if you need a record - the threads themselves don’t move across.
2. Go to Claude’s import page and log in. It gives you a prompt to copy.
3. Paste the prompt into ChatGPT (a thinking model works best). ChatGPT writes out everything it knows about you, your work and your preferences.
4. Paste that into Claude’s memory settings, fill any gaps, and save.
5. Connect your tools: click the plus button, open Connectors, and sign in to email, calendar, Xero and anything else you use.
6. Turn one repeated job into a Skill. Ask Claude “I want to create a skill”, describe the job, answer its questions, and save it.
7. If you’re a team, cancel the ChatGPT seats only once everyone has used Claude for a couple of weeks.

If you’d rather have Claude set up properly than work through all this yourself, that’s what my Claude setup for NZ businesses covers: the right plan and privacy settings, connected to your tools, Skills for the jobs you repeat, and handed over running.
