Starting A Bath Bomb Business: Business Structure & Registration

You can’t start your bath bomb business without legally registering it first. To do this, you will need to choose the right business structure and then follow the relevant requirements to register under that structure. In New Zealand, the most common business structures are a sole trader, partnership, and a company – let's take a closer look at each one.

Sole Trader

If you want to be the sole owner and operator of your bath bomb business, registering as a sole trader might be the simplest option. The setup process is straightforward – you just need to register a trading name with the New Zealand Companies Office if you’re trading under a name different from your own. For more guidance, please visit register a business name.

While becoming a sole trader is quick and cost-effective, there are some important limitations to consider. This structure doesn’t support external investors or many expansion opportunities, and it doesn’t separate your personal and business liabilities. That means you’ll be personally responsible for any debts or legal issues that arise.

Partnership

A partnership can be a great way to divide responsibilities and leverage each partner’s strengths. Like a sole trader, setting up a partnership is relatively simple – you’ll need to register a trading name with the New Zealand Companies Office if you plan to trade under a name different from your personal names. Please see register a business name for further details.

However, partnerships share many of the same limitations as sole trader structures. Liability is shared equally between all partners, which can be risky if something goes wrong. That’s why having a strong and clear Partnership Agreement is crucial – it outlines roles, responsibilities, and how disputes will be handled.

Company

Many people assume that company structures are only for large businesses – but that’s not the case. Even if you’re just starting out or plan to remain small, you can register a company as a sole director and shareholder by applying through the New Zealand Companies Office.

The main advantage of a company is that it offers limited liability, which means your personal assets are more protected. It’s also better suited for growth – for example, if you want to attract investors or expand into franchising.

That said, companies are more regulated. You’ll need to identify officeholders, comply with Companies Office requirements, and have the appropriate legal documents in place. Because of this added complexity, it’s a good idea to get support from a legal expert to ensure everything is set up properly from the start.

What Legal Requirements Does My Bath Bomb Business Need to Meet?

Legal compliance is an essential part of starting and running any type of business. When starting your bath bomb business, it's important to do your due diligence and determine exactly which laws apply to your business.

It can be confusing to figure this out on your own, so speaking with a legal expert and getting advice tailored specifically to your bath bomb business is a smart move.

In the meantime, we’ve listed some key areas of legal compliance you may want to keep in mind.

New Zealand Consumer Law (Consumer Guarantees Act & Fair Trading Act)

To stay compliant with New Zealand consumer law – including the Consumer Guarantees Act and Fair Trading Act – you’ll need to meet product safety guarantees, ensure transparency in your marketing practices, and implement consumer-friendly policies such as fair refunds and warranties. These laws cover a broad range of requirements, so it’s important to understand your obligations. If you're unsure, don’t hesitate to reach out to a legal expert for tailored advice.

Cosmetics Product Regulations

Bath bombs are generally considered cosmetic products in New Zealand, which means they are not regulated by Medsafe unless you make therapeutic claims (such as relieving pain or treating skin conditions). However, if you manufacture or import cosmetic ingredients, you should ensure they comply with New Zealand safety and chemical regulations. If therapeutic claims are made, additional requirements under the Medicines Act 1981 may apply.

In New Zealand, the use, importation, and handling of chemicals – including fragrances, colourants, and other cosmetic ingredients commonly found in bath bombs – is subject to regulations designed to ensure public safety. You should verify that any chemicals you use meet the relevant New Zealand safety standards and reporting requirements, and, if necessary, register or obtain authorisation from the appropriate regulatory bodies.

Import/Export Laws

If you're importing ingredients for your bath bomb business from overseas or planning to ship your products internationally, it's important to understand New Zealand’s import and export regulations. You’ll need to ensure that any ingredients or materials comply with safety standards set by regulators such as the New Zealand Customs Service, and if chemicals are involved, that they meet the relevant New Zealand safety requirements. It's also essential to know which substances are restricted or prohibited, and to complete all required customs declarations accurately. Understanding these rules helps you avoid border delays, fines, or penalties – and ensures your business operates smoothly and legally.

Employment Law

When you hire employees to work in your business, you’ll need to ensure you meet your obligations as an employer under New Zealand employment law. This includes complying with the Employment Relations Act 2000, paying at least the minimum wage, and meeting all workplace health and safety requirements under the Health and Safety at Work Act 2015. These responsibilities are an essential part of employing staff, so it’s important to familiarise yourself with the relevant laws and integrate them into your business practices.

Licences And Permits 

Depending on where you operate, you may need local authority permits, zoning approvals, or health and safety inspections. It’s important to research your local government’s requirements before starting your business – the last thing you want is to face fines or be forced to shut down because you're not in line with the regulations.

Intellectual Property (IP) Law

Your brand is one of your most valuable assets. From your business name and logo to your product packaging and scent combinations, these elements may be protected under intellectual property law. Registering a Trade Mark for your name, logo, or slogan helps you secure legal ownership and prevent others from using similar branding. You may also want to consider copyright protections for original designs or written content and Non-Disclosure Agreements (NDAs) to protect trade secrets when working with suppliers or contractors.

Data & Privacy Law

If you collect customer information online, you’ll need to comply with the Privacy Act 2020 and the New Zealand Privacy Principles. This typically means having appropriate privacy protections in place, obtaining the necessary consents, and maintaining key legal documents – such as a Privacy Policy – to ensure you’re handling and protecting customer data properly.

Will I Need Any Legal Documents To Start A Bath Bomb Business?

Yes, legal documents are an essential part of starting and running a business. Some documents, like a Privacy Policy or an Employment Contract, may be legally required. Others might not be mandatory, but they play a crucial role in protecting your bath bomb business and setting you up for long-term success.

A legal expert can help you identify the specific agreements that are most relevant to your business and tailor them to suit your needs.

Here are a few legal agreements you may want to consider:

• Supply Agreement
• Distribution Agreement
• Staff Handbook
• Workplace Policies
• Website Terms & Conditions
• Non-Disclosure Agreements (NDAs)
