Registering a Business
Once your business idea, niche, plan, goals, mission and vision are clear, the next step is setting up the business correctly.
Learning Objectives
- Understand the basic steps involved in registering a business.
- Learn the difference between a sole trader and a company setup.

- Know when to seek professional advice.
Before You Register
Confirm Your Business Idea
Make sure you have completed the earlier lessons on choosing a business, finding your niche, market research, competitor analysis, SWOT, and planning.
Choose Your Name
Your business name should be easy to remember, professional, available, and suitable for your brand.
Choose a Structure
Most small businesses begin as a sole trader, partnership, or company. Each structure has different legal and financial responsibilities.
Common New Zealand Setup Steps
- Choose your business structure.
- Choose and check your business name.
- Set up a RealMe login if required.
- Get or confirm your New Zealand Business Number if applicable.
- Set up or update your myIR account.
- Register your company with the Companies Office if you are forming a company.
- Register for GST if required.
- Open a business bank account.
- Check insurance, licences, permits, and industry requirements.
Sole Trader vs Company
Sole Trader
A sole trader is usually the simplest way to begin. Business.govt.nz explains that a sole trader does not need to register the business with a government agency in the same way as a company, but must tell Inland Revenue they have started working for themselves.
- Simple to start.
- Lower setup cost.
- You control the business.
- You are personally responsible for business debts and obligations.
Company
A company must be registered with the Companies Office. When a company is registered, it receives a New Zealand Business Number, and it must meet company obligations such as keeping details up to date and filing annual returns.
- Separate legal structure.
- More formal setup.
- More compliance obligations.
- Can look more professional for some customers and suppliers.
New Zealand Business Number
A New Zealand Business Number, often called an NZBN, is a unique identifier for New Zealand businesses. It helps share core business information such as trading name, address, and contact details with government agencies, suppliers, customers, and other organisations.
GST Basics
In New Zealand, GST is charged at 15% on most goods and services. Inland Revenue explains that you must register for GST if your taxable activity has turnover of at least $60,000 in the last 12 months, or you expect it to reach at least $60,000 in the next 12 months. You must also register if you add GST to your prices.
- Do not register for GST just because you start a business.
- Track your turnover carefully.
- Understand whether your prices include or exclude GST.
- Ask an accountant or Inland Revenue if you are unsure.

Common Mistakes
❌ Choosing a Name Too Quickly
Check whether the name is suitable, available, and not too similar to another business.

Even small businesses need good records and clear tax planning from the beginning.
❌ Forgetting Licences or Permits
Some industries require permits, registrations, professional approvals, or local council checks.
