How to Register a Business in NZ: Step-by-Step

Starting a business in New Zealand is surprisingly straightforward compared to many other countries. Whether you're planning to operate as a sole trader, partnership, or limited company, the registration process can be completed in just a few days—and in some cases, within 24 hours. This guide walks you through exactly what you need to do, the costs involved, and the timelines you can expect.

Understanding Your Business Structure Options

Before you register, you'll need to decide which business structure suits you best. Your choice affects your tax obligations, legal liability, and administrative requirements.

Sole Trader

A sole trader is the simplest structure and ideal if you're working alone. You'll need an IRD number and a business bank account, which you can set up on day one. The entire process takes just 1-3 days from start to trading^[1]. You're personally liable for any business debts, but there's minimal paperwork and lower setup costs.

Partnership

If you're starting with one or more partners, you can operate as a partnership. You'll need to register with the Companies Office and provide details of all partners along with a physical New Zealand address^[2]. Partnerships require annual returns and, depending on size, may need audited financial statements.

Limited Company (Ltd)

A limited company offers the most protection because your personal assets are separate from the business. You'll need at least one director (who must be a New Zealand or Australian resident) and one shareholder^[2]. There are no minimum capital requirements, and registration takes just 30 minutes online with instant approval in most cases^[1].

Step-by-Step Registration Process

Step 1: Choose and Reserve Your Business Name

Your first task is to check that your chosen business name is available and reserve it. You can do this through the Companies Office website using your RealMe login^[4]. If you don't have a RealMe account, you'll need to create one first.

Name reservation costs $10.22 and keeps your name protected for 20 working days, usually processed the same day^[1]. This gives you time to get your other details sorted before formal registration.

Step 2: Register Your Company Online

Once you've reserved your name, you're ready to register. The online registration takes just 10-30 minutes and costs $115.92 (or $135.92 if filing on paper)^[1]. You'll need to provide:

• Director details and addresses
• Shareholder information
• Your registered company address (a physical address in New Zealand)
• Details of your company's shares structure

Registration is processed instantly in most cases. You'll immediately receive your company number (also called your NZBN—New Zealand Business Number) and a certificate of incorporation^[1].

Step 3: Register for Tax

Your company automatically gets an IRD number when registered with the Companies Office. You'll receive it within 1-2 business days in your RealMe or myIR account^[1].

You'll also need to register for GST if your turnover exceeds or is expected to exceed $60,000 per year^[1]. GST registration takes just 10-15 minutes online and is processed within 1-2 business days. You can backdate your GST registration up to 6 months if needed.

Step 4: Open a Business Bank Account

Once you have your company number and IRD number, you can apply for a business bank account. Most banks process applications within 1-5 business days^[1]. You'll need to provide:

• Your certificate of incorporation
• Company number (NZBN)
• Director ID (driver's license or passport)
• Proof of address for directors

Having a separate business bank account keeps your finances organised and is essential for GST purposes.

Step 5: Set Up Essential Business Operations

Once your bank account is active, you're getting close to trading. However, there are a few more things to sort out:

Business Insurance

Depending on your industry, you may need public liability insurance, professional indemnity insurance, or contents insurance. You can get quotes online the same day and activate coverage immediately or the next day^[1].

Shareholder Agreement (If You Have Multiple Owners)

If your company has more than one shareholder, a shareholder agreement protects everyone's interests. You can use a DIY template (1-2 days) or have a lawyer draft one (1-2 weeks, costing $500-3,000)^[1].

Employment Agreements (If You're Hiring)

If you're planning to hire employees, you must provide them with a written employment agreement before they start work. Template-based agreements take 1-2 days, while custom-drafted agreements take 3-5 days^[1].

Industry-Specific Licensing Requirements

Some industries require additional licenses or registrations before you can legally operate. These can add significant time to your setup:

Industry	License Required	Typical Timeline
Real Estate	REA License	2-4 weeks
Electrical Work	EWRB Registration	2-6 weeks
Building/Construction	LBP License	4-8 weeks
Financial Services	FMA License	3-6 months
Alcohol Sales	Alcohol License	2-4 months
Food Business	Food Control Plan	2-4 weeks

Check with your industry regulator early in the process to avoid delays.

Key Costs to Budget For

Here's what you can expect to pay when registering your business:

• Company name reservation: $10.22^[1]
• Company registration: $115.92 online^[1]

• IRD number: Free
• Business bank account: Free (though some banks may have monthly fees)
• Shareholder agreement (lawyer-drafted): $500-3,000^[1]

For a basic sole trader or simple limited company, you're looking at minimal upfront costs—often under $200 before insurance.

Important Compliance Requirements

Once you're registered, you'll have ongoing legal obligations:

• Annual returns: All companies must file annual returns with the Companies Office^[4]
• Tax returns: You must file income tax returns with the IRD annually
• GST returns: If registered for GST, you'll file returns every two months or annually depending on your turnover
• Financial reporting: All New Zealand firms must prepare financial reports within five months of the balance sheet date, though small companies may be exempt from audit requirements^[5]
