Microsoft 365 Copilot is the generative-AI assistant built into Word, Excel, Outlook, PowerPoint, Teams and the wider Microsoft 365 suite. For New Zealand organisations weighing it up in 2026, the real questions are practical: what does it actually do, where does your data live, does it meet the Privacy Act 2020, and what does it cost in New Zealand dollars? This guide answers those questions plainly, corrects some common misconceptions about local data residency, and sets out a sensible way to roll Copilot out without overspending.
Key Points
- What it is: a paid AI assistant grounded in your own Microsoft 365 data, working inside Word, Excel, Outlook, PowerPoint and Teams.
- Free tier: Copilot Chat is included with an eligible Microsoft 365 subscription, but it uses web data, not your files.
- Agents: Microsoft Agent 365 (generally available 1 May 2026, US$15/user/month) governs AI agents across the organisation.
- Model choice: OpenAI models plus Anthropic Claude Sonnet 4 and Opus 4.1, enabled by default in NZ commercial tenancies.
- Data residency: core M365 content can sit in the Auckland NZ North region, but Copilot prompt/response storage is not guaranteed to stay in New Zealand.
- NZ pricing: enterprise add-on NZ$48.50/user/month; Copilot Business NZ$29.14/user/month (promo to 31 Dec 2026), both excl GST and on a qualifying base licence.
What is Microsoft 365 Copilot?
Microsoft 365 Copilot is a paid AI layer that sits inside the Microsoft 365 apps your team already uses and can draft, summarise, analyse and search across your own work content. Unlike a standalone chatbot, it is “grounded” in your organisation’s data: it reads the emails, files, chats and meetings you already have permission to see and uses them to answer prompts in context.
How Copilot actually works
When you ask Copilot something, it combines your prompt with relevant information pulled from Microsoft Graph — the index of your organisation’s SharePoint, OneDrive, Outlook and Teams content — and sends that package to a large language model. The model’s answer is returned inside the app, with citations back to the source files. Copilot only surfaces content you are already permitted to open, so it respects existing access controls rather than bypassing them.
Copilot Chat versus Microsoft 365 Copilot
There are two tiers, and the difference matters for budgeting. Microsoft 365 Copilot Chat is included at no extra cost for users with an eligible Microsoft 365 subscription, but it answers from public web data and does not read your internal files. The paid Microsoft 365 Copilot add-on unlocks the grounded, in-app experience across Word, Excel, Outlook, PowerPoint and Teams. If you only need a web-grounded assistant, the free Chat tier may be enough; if you want AI working over your own documents, you need the paid licence.
The shift to agentic AI and Agent 365
The biggest change since Copilot launched in 2023 is the move from a single assistant to “agents” — configurable AI helpers that can carry out multi-step tasks. Instead of only drafting an email, an agent can gather figures from Excel, build a first-draft PowerPoint deck and schedule a review in Teams as a sequence. For New Zealand firms, the appeal is offloading repetitive administrative work; the risk is losing track of how many agents exist and what they can touch.
What Agent 365 does
Microsoft Agent 365 reached general availability on 1 May 2026 as a control plane for managing AI agents across an organisation. It provides a registry to see which agents exist, extends Microsoft Entra identity and network controls to those agents, and helps IT restrict where agents can connect and what data they can move. Agent 365 is priced at US$15 per user per month. In practice it answers the governance question — “who approved this agent and what can it do?” — that grows more pressing as agent use spreads.
Building agents with Copilot Studio
Copilot Studio is Microsoft’s low-code tool for building custom agents, from an internal HR helper to an external website assistant. Many Microsoft 365 Copilot licences include Copilot Studio access for building agents, while heavier or external-facing use draws on a separate capacity pack (see the pricing section). Agents built in Copilot Studio can be governed through Agent 365, keeping custom automation inside the same security boundary as everything else.
Copilot across the Microsoft 365 apps
Once licensed, Copilot appears inside the day-to-day apps rather than as a separate destination. Its most-used capabilities are:
- Word — draft, rewrite and summarise documents, grounded in your own files and templates.
- Excel — build formulas and pivot tables, spot trends, and generate Python for deeper analysis.
- Outlook — triage the inbox, summarise long threads and draft replies in your tone.
- PowerPoint — turn a brief or a Word document into a first-draft deck with speaker notes.
- Teams — produce live meeting summaries and pull out decisions and action items.
The gains are real but uneven: staff who live in email and documents tend to benefit far more than occasional users, which is central to getting a return on the licence cost.

Model choice: OpenAI and Anthropic’s Claude
Microsoft 365 Copilot is no longer tied to a single model. Alongside OpenAI’s models, Anthropic’s Claude is now available inside Copilot — specifically Claude Sonnet 4 and Claude Opus 4.1 — across experiences including the Researcher agent, Copilot Studio, Word, Excel, PowerPoint and Copilot Chat. This lets a business pick a model that suits a task rather than being locked to one provider.
Two caveats matter for New Zealand. First, model availability is not uniform across every app, tenant or release channel, so what appears for one team may not appear for another straight away. Second, Anthropic’s models are enabled by default in commercial tenancies and disabled in the EU and UK; a New Zealand commercial tenant will typically have Claude available, but an administrator can turn model options on or off. Treat the choice as a policy decision, not just a user preference.
Data residency, privacy and the New Zealand context
Data residency is the single most misunderstood part of Copilot in New Zealand, so it is worth being precise. There are two different things at play: where your core Microsoft 365 content is stored, and where Copilot’s interaction content (your prompts and its responses) is stored.
Where is your data actually stored?
Microsoft’s New Zealand North cloud region opened in Auckland in December 2024, and core Microsoft 365 data such as SharePoint, Exchange and OneDrive content can be held in-country for tenants with a New Zealand default geography. However, Copilot’s own content of interactions is governed separately by Microsoft’s data-residency product terms, and New Zealand is not currently on the list of geographies with an at-rest storage commitment for that interaction content. In plain terms: the documents Copilot reads can live in New Zealand, but there is no guarantee your prompts and Copilot’s replies are stored on New Zealand shores. Any claim to the contrary should be checked against Microsoft’s current terms before you rely on it. Organisations with strict requirements should review Microsoft’s Advanced Data Residency and Multi-Geo options and understand exactly what each covers. Our overview of data residency for New Zealand goes into the wider trade-offs.
Privacy Act 2020 and Microsoft Purview
Copilot operates inside your existing Microsoft 365 tenant and, under Microsoft’s terms, your business data is not used to train the foundation models. That helps with Privacy Act 2020 obligations, but it does not make you compliant on its own. Microsoft Purview is the toolset most NZ organisations pair with Copilot to classify sensitive information (for example IRD numbers or health records), apply sensitivity labels, and reduce the risk of an AI answer over-sharing data a staff member technically has access to. Good labelling before rollout does more for compliance than any single setting.
Māori data sovereignty considerations
For iwi organisations, health providers and public-sector agencies, Māori data sovereignty — the principle that data about Māori should be subject to Māori governance — is a real consideration when introducing AI. Copilot does not resolve this automatically. It requires deliberate decisions about what data agents may access, where it is stored, and who approves its use, ideally documented alongside your wider information-governance policy.
Microsoft 365 Copilot pricing in New Zealand (2026)
Copilot is a premium add-on, and the headline figure is rarely the full cost because it sits on top of a qualifying Microsoft 365 base licence. The table below shows current New Zealand list pricing; figures exclude GST and most require an annual commitment.
| Plan | NZ price (per user/month, annual) | Notes |
|---|---|---|
| Microsoft 365 Copilot (enterprise add-on) | NZ$48.50 | Needs a qualifying Microsoft 365 base licence. |
| Microsoft 365 Copilot Business (add-on) | NZ$29.14 (from NZ$34.00) | Promotional price through 31 December 2026; for organisations up to 300 users. |
| Microsoft 365 Business Standard with Copilot | NZ$38.00 | Bundle including the base suite plus Copilot. |
| Microsoft 365 Business Premium with Copilot | NZ$51.80 | Bundle with added security and device management. |
| Copilot Studio (capacity pack) | NZ$323.60 | Tenant-wide pack of 25,000 Copilot Credits; pay-as-you-go also available. |
| Microsoft 365 Copilot Chat | Included | Free with an eligible Microsoft 365 subscription; web-grounded, not your files. |
What you need before you can buy
You cannot buy the enterprise Copilot add-on on its own — it requires an eligible Microsoft 365 licence underneath it, so the true per-seat cost is the base plan plus Copilot. If you are still choosing that base plan, our guide to Microsoft 365 for business in New Zealand compares the underlying options. Prices change often; always confirm the current figure on Microsoft’s New Zealand site before committing.
How Copilot compares with other AI assistants
Copilot is not the only workplace AI option, and the right fit depends on which productivity suite you already run. The table compares the main contenders on their core positioning.
| Tool | Best for | Works inside |
|---|---|---|
| Microsoft 365 Copilot | Teams already standardised on Microsoft 365 | Word, Excel, Outlook, PowerPoint, Teams |
| Gemini for Google Workspace | Organisations on Google Workspace | Docs, Sheets, Gmail, Slides, Meet |
| ChatGPT Enterprise | General-purpose AI outside one office suite | Web app, API, connectors |
| Claude (Anthropic) | Long-document reasoning and writing | Web app, API (also available inside Copilot) |
| Zoho Zia | Small businesses on the Zoho suite | Zoho apps and CRM |
| Notion AI | Teams that centre work in Notion | Notion workspace |
If your business runs on Microsoft 365, Copilot’s advantage is that it works where your data and permissions already are. If you are on another suite, a rival assistant will usually integrate more naturally.
How to get started in a New Zealand business
A measured rollout beats a blanket one. The steps below reflect what tends to work for Kiwi small and medium organisations.
- Tidy your data first. Copilot answers from your files; messy or out-of-date SharePoint content produces confident but wrong answers. Fix permissions and archive stale material before you switch it on.
- Start with intensive users. Give the first licences to people who live in documents, email and meetings — executive assistants, project managers, analysts — where reclaimed time is easiest to measure.
- Set governance early. Decide who can create agents, apply Purview sensitivity labels, and use Agent 365 or equivalent controls to keep visibility over what is running.
- Train people on prompting. The gap between a vague prompt and a specific one is large; short internal training pays back quickly.
- Measure before you scale. Review time saved and output quality after a pilot, then expand to the teams where the numbers justify it.
For broader context on lifting output across the suite, see our notes on professional productivity, and if you are planning a whole-of-suite move, our guide to the wider Microsoft 365 rollout for New Zealand organisations covers the surrounding decisions.
Common mistakes to avoid
Most disappointing Copilot rollouts fail for predictable reasons rather than because the technology is weak.
- Assuming NZ data residency for prompts. As covered above, Copilot’s interaction content is not guaranteed to stay in New Zealand; verify the terms rather than assume.
- Skipping data hygiene. Grounding AI in disorganised files guarantees unreliable answers.
- Licensing everyone at once. Paying for occasional users who never build the habit is the fastest way to a poor return.
- Ignoring over-sharing risk. Without sensitivity labels, Copilot can surface data a user technically can open but was never meant to see.
- Treating output as final. AI drafts still need human review for accuracy, tone and legal risk; it assists, it does not sign off.
- No agent governance. Letting agents proliferate without a registry creates unmanaged “shadow AI.”
Who Microsoft 365 Copilot suits
Copilot makes most sense for organisations already committed to Microsoft 365 with reasonably well-organised data and a core of heavy document, email and meeting users. It is a weaker fit for very small teams with light admin loads, businesses on other productivity suites, or organisations that have not yet sorted out permissions and information governance.
It is also fair to weigh the trade-offs of deepening reliance on a single vendor. Microsoft’s market position and past conduct have long attracted scrutiny, and lock-in is a legitimate strategic consideration; a fuller account of the debate is catalogued on Wikipedia. Businesses wanting to keep options open, or to trim licensing costs, may also pair Microsoft tools with free and open-source office suites for lighter use cases.

Frequently Asked Questions
Is my organisation’s data used to train Microsoft’s AI models?
No. Under Microsoft’s terms, Microsoft 365 Copilot operates inside your existing tenant and your business data is not used to train the underlying foundation models. It remains subject to your existing access controls and encryption.
Are Copilot prompts and responses stored in New Zealand?
Not guaranteed. Core Microsoft 365 content can be held in the Auckland-based New Zealand North region, but Copilot’s content of interactions is governed by Microsoft’s data-residency terms, and New Zealand is not currently on the list of geographies with an at-rest storage commitment for that interaction content. Check the current terms, and review Advanced Data Residency options, if this matters to you.
How much does Microsoft 365 Copilot cost in New Zealand?
The enterprise add-on is NZ$48.50 per user per month on an annual plan, on top of a qualifying base licence. The Copilot Business add-on for organisations up to 300 users is NZ$29.14 per user per month (down from NZ$34.00) on a promotion running through 31 December 2026. Prices exclude GST and can change.
Can I choose which AI model Copilot uses?
Yes, within limits. Copilot supports OpenAI models and Anthropic’s Claude (Sonnet 4 and Opus 4.1) across experiences such as Researcher, Copilot Studio, Word, Excel and PowerPoint. Availability varies by app and tenant, and administrators can enable or disable model options, so what you see depends on your organisation’s settings.
Does Microsoft 365 Copilot support te reo Māori?
Not as a Copilot language at this stage. Microsoft Translator has supported te reo Māori for several years, but te reo Māori is not currently on Microsoft 365 Copilot’s own list of supported languages. Check Microsoft’s supported-languages page for the latest position before relying on it.
