How to Change Your NZ Company Name: A Step-by-Step Guide

Whether you are rebranding, correcting a typo, or pivoting your business, changing your NZ company name is a common and entirely legal step. Here is what it involves.

Step 1: Check Name Availability

Before you apply, search the Companies Register to confirm the new name is available. A name is available if it is not identical or too similar to an existing company, no registered trademark prevents its use, and it does not include restricted words (like "bank", "insurance", or "trust" without approval).

Step 2: Apply via the Companies Register

Log in to the Companies Register online portal with your RealMe account or via your solicitor. Locate your company, choose "Update company details", and submit a name-change application. You will need a special or unanimous shareholder resolution confirming the name change. The Companies Office usually processes the application within 1 working day. The fee is currently NZ$10.

Step 3: Update Your IRD Number

Your company IRD number does not change, but IRD needs to know about the new trading name. Update this via myIR under "Update my details". Your GST registration, PAYE account, and other tax accounts all follow the same IRD number — no new registration is needed.

Step 4: Notify Your Bank

Most banks require a letter confirming the name change (a copy of the updated Companies Register entry works) plus certified ID from a director. Allow up to 5 business days. Your account number does not change but new cards and statements will reflect the new name.

Step 5: Update Contracts and Agreements

Review every significant contract to see whether a name change triggers a novation clause. Many standard contracts (leases, supply agreements, insurance policies) are with the company entity itself (identified by its company number), so the name change does not void them — but you should notify counterparties in writing and update the name on future correspondence.

Step 6: Domain and Online Presence

• Register your new domain name before changing anything else (someone else might grab it)
• Set up 301 redirects from the old domain so SEO rankings transfer
• Update Google Business Profile, LinkedIn, Facebook, and any other business listings
• Update your email addresses if they reflect the old name

Step 7: Update Physical Collateral

Letterheads, business cards, invoices, signage, and packaging all need updating. You have no strict legal deadline, but you must not actively misrepresent the company name on formal documents.

Do You Need a Lawyer or Accountant?

For a straightforward name change, most directors manage the process themselves. An accountant or company secretary is useful if you have complex shareholder arrangements or if the name change is part of a broader restructuring.
