Setting Up a Business Bank Account for a New NZ Company: A Practical Guide
Opening a business bank account is one of the first things a new NZ company needs to do. Here is what you need, which banks to consider, and how to get set up fast.
Once your NZ company is registered, you need a business bank account before you can invoice clients or receive payments. This guide covers everything you need to know to get set up quickly.
Why You Need a Separate Business Account
Mixing personal and business finances is one of the most common mistakes new company directors make. It creates accounting headaches, makes GST returns harder to prepare, and can complicate any future due diligence if you ever sell the business. Open a separate business account on day one.
What Documentation You Need
NZ banks require the following to open a business account:
- Your NZ Companies Register number (your company number from the Companies Office)
- A copy of your certificate of incorporation (available from the Companies Register)
- Proof of identity for all directors and signatories (passport or driver licence)
- Proof of address for directors (utility bill or bank statement, less than 3 months old)
- Your business address
Some banks also ask for a business plan or description of your activities for new companies.
NZ Business Bank Options in 2026
The main options for new NZ companies include: ANZ, ASB, BNZ, Kiwibank, and Westpac, all of which offer business transaction accounts. Some banks offer fee-free periods for new businesses, so it is worth comparing current promotions.
For online-first businesses, alternative providers like Wise Business can be useful for international payments, though they are not full NZ banking providers.
Tips for Getting Set Up Fast
- Apply online where possible: most major NZ banks now allow online applications for simple company structures (sole director, no complex ownership)
- Book an in-branch appointment if your company has multiple directors or complex ownership, as these often need a face-to-face meeting
- Set up internet banking and mobile banking immediately so you can pay suppliers and receive payments from day one
- Ask your accountant which bank they prefer working with, as some accounting software integrates better with certain banks
Working with an Accountant from the Start
Many new company directors set up their bank account at the same time as engaging an accountant. Your accountant can help you link your business account to Xero or MYOB for automatic reconciliation, saving significant time on bookkeeping each month.
