Interior Design IP Ownership in New Zealand

Interior designers often assume that the person who pays for a project owns everything created for it. That assumption can cause real problems when a client asks for editable CAD files, a contractor reuses a concept in another fit-out, or a studio discovers its supplier list has been copied into a competing proposal.

The biggest mistakes are leaving ownership out of the interior design contract, treating mood boards and plans as the same thing, and forgetting that contractors are not employees. Clear terms help you decide who can use concepts, drawings, renders, schedules, photos, templates, supplier contacts and finished client deliverables.

For New Zealand studios and freelance designers, IP ownership is not just a creative issue. It affects pricing, client handover, resale of design packages, portfolio use, contractor management and the value of the studio if you later sell the business.

Interior Design IP Checklist for Client Deliverables

A good interior design IP position separates what the client needs to use from what the designer or studio needs to keep for future work.

Most disputes start because everyone uses the word design to mean different things. A client may think design means every file and source document ever created. A contractor may think it means only the final PDF presentation. A studio may think it means the design system, templates, library, supplier relationships and all editable files.

Use a practical inventory at the start of each project. It should cover the assets created for the client and the assets that belong to your business before the project begins.

• Concept work: sketches, design narratives, look and feel boards, finishes concepts, colour palettes and spatial ideas.
• Presentation materials: mood boards, sample boards, 3D renders, walkthrough images, client decks and proposal documents.
• Technical documents: CAD drawings, floor plans, reflected ceiling plans, joinery drawings, elevations, product specifications and schedules.
• Procurement material: furniture, fixtures and equipment schedules, supplier lists, pricing notes, lead time records and order templates.
• Business assets: your standard CAD blocks, proposal templates, standard clauses, design methodology, estimating tools, supplier database and internal style library.
• Third-party material: supplier product photos, manufacturer data, stock images, subcontractor drawings, software libraries and licensed render assets.

The goal is not to make every client sign away all rights. Many clients simply need enough rights to use the completed design for their fit-out, renovation or commercial space. The designer or studio may need to keep ownership of background tools and the ability to show the work in a portfolio, reuse non-confidential methods and keep its supplier network protected.

A practical project file should answer five questions:

1. What final deliverables are included in the fee?
2. Will the client receive editable source files, or only PDFs, images and schedules?
3. Can the client build, modify or reproduce the design without the designer?
4. Can the designer reuse elements, templates and ideas in other projects?
5. Who is responsible for third-party licences, supplier permissions and contractor outputs?

These answers should appear in the interior design contract or terms and conditions, not only in email discussions. A fee proposal can describe the creative scope, but ownership and usage rights usually need clearer legal wording.

Who Owns Concepts, Plans, Renders and Supplier Lists?

In New Zealand, copyright ownership depends on the type of work, who created it, the creator's role and any written agreement that changes the default position.

The Copyright Act 1994 protects original works that are recorded in a material form. For interior design, this can include drawings, plans, diagrams, renders, written specifications, presentation decks, schedules and some compilations. Copyright does not usually protect a bare idea, general style, trend, colour inspiration or broad concept. It protects the particular expression of the work.

That distinction matters. A client cannot usually own the general idea of a warm minimalist reception area with curved seating and local timber finishes. They may, however, own or have a licence to use the specific drawings, renders and specifications created for their project.

New Zealand copyright law has default rules, but contracts can often override them. The most common scenarios for interior design businesses are:

• Employee-created work: if a designer creates work in the course of employment, the employer will usually own copyright unless the employment agreement says otherwise.
• Freelancer or contractor work: the contractor may own copyright as creator, or the commissioning party may own certain commissioned works, depending on the work and arrangement. A written assignment removes doubt.
• Client-commissioned design work: a paying client may have ownership or at least strong usage rights in commissioned plans and drawings unless the contract reserves ownership for the designer.
• Pre-existing studio materials: templates, standard details, libraries and methods should remain with the studio if the contract says they are background IP.

The safest position for a studio hiring freelancers is to include a design deliverables IP assignment in the contractor or subconsultant agreement. It should say that the contractor assigns to the studio all IP in project-specific work created for the engagement, including concepts, drawings, CAD files, renders, schedules, written specifications and other deliverables. It should also deal with moral rights, confidentiality and third-party materials.

For a freelance interior designer working directly with a client, the decision is commercial. You might assign ownership of final documents for a premium fee, or keep ownership and give the client a licence to use the design for one premises, one project and one implementation. If the client wants to roll the design out across multiple stores, locations or developments, that should be priced and documented.

Supplier lists sit in a slightly different category. A basic list of publicly available supplier names may not attract strong copyright protection. A curated database with notes, pricing history, contacts, lead times, preferred discounts, installation issues and project-specific recommendations may be protected as a compilation, and it may also be confidential business information. In practice, confidentiality clauses, access controls and non-solicitation terms are often more useful than relying on copyright alone.

Mood boards also need care. A mood board may include your original layout and selections, but many images on it may belong to suppliers, photographers, manufacturers or stock libraries. Giving a client ownership of a mood board does not mean the client can use every third-party image for marketing, social media or advertising. Your contract should separate your design work from third-party content and state any limitations clearly.

What Your Interior Design Contract Should Say

An interior design contract in New Zealand should state whether the client receives ownership, a licence, or only limited use of the final deliverables.

The right answer depends on the business model. A high-end residential designer may want to give the client broad rights to use the final plans for their home, while keeping all templates, concept libraries and portfolio rights. A studio designing a hospitality venue may want to restrict reuse so the client cannot use the same design across a second site without paying for it. A commercial roll-out designer may charge per location and grant rights location by location.

Your contract should avoid vague wording such as all designs belong to the client or designer owns all IP. These statements are too blunt for real projects. A better structure is to separate background IP, project IP, final deliverables, source files and third-party materials.

Ownership or Licence

The contract should say whether IP in the final deliverables is assigned to the client or licensed to the client. An assignment transfers ownership. A licence allows use without transferring ownership.

If you grant a licence, define the scope. For example, the client may use the final drawings and schedules for the fit-out of a named premises, for construction, installation, maintenance and future repairs. The licence might prohibit resale, use at another site, copying the design for another business, or giving editable files to another designer except for construction or compliance purposes.

If you assign ownership, decide whether that happens when the work is created, when the final invoice is paid, or when a separate assignment is signed. Many studios make rights conditional on full payment. That gives the business leverage if a client takes the drawings but refuses to pay the final invoice.

Final Deliverables Versus Working Files

Clients often ask for everything at the end of a project, but editable source files are different from final deliverables.

A final deliverable might be a PDF drawing set, a rendered image, a finishes schedule or a procurement schedule. A working file might be the original CAD file, Revit model, SketchUp file, Photoshop file, InDesign file, cost spreadsheet or supplier database extract. Working files may reveal your templates, methods, shortcuts and internal notes.

Your contract can state that working files are not included unless expressly agreed. If the client needs source files for construction, facility management or future maintenance, charge for them and set limits. You may want the right to remove internal comments, confidential supplier pricing, unused concepts and embedded third-party assets before delivery.

Revisions, Unused Concepts and Kill Fees

Unused concepts should not automatically become client property just because they appeared in an early presentation.

Interior design projects often involve several rounds of options. A client might reject one concept, then later ask another designer to develop it. Your contract should say whether rejected or unused concepts remain yours, and whether the client can use them only if they pay an additional fee.

If a project ends early, the contract should say what rights the client receives in partially completed work. For example, the client may receive a licence to use paid-for completed deliverables only, while drafts, rejected concepts and unpaid work remain with the designer.

Portfolio, Photography and Marketing Rights

A designer should not assume they can publish client work just because they created it.

Portfolio rights should be written into the contract. You may want the right to photograph the completed space, name the project, enter awards, post images on social media and use selected materials in pitches. Clients may need confidentiality for private homes, hotels before launch, retail concepts or commercially sensitive fit-outs.

A balanced clause can allow portfolio use after completion, subject to reasonable confidentiality limits and approval for sensitive images. Also consider who owns professional photographs. If professional photographs are commissioned and paid for, the commissioning party may own copyright by default unless the photography agreement says otherwise. The photography agreement should still spell out who owns the photos, who can use them, where they can be published, whether the photographer can use them in their portfolio, and any client confidentiality limits.

Hiring Freelance Designers and Contractors Without Losing Control

A studio that hires contractors should secure project IP before the contractor starts work, not after the client asks for handover.

Interior design studios regularly use freelance CAD technicians, render artists, stylists, procurement assistants, lighting consultants and joinery drafters. These people may create valuable parts of the client deliverables. If their contracts are silent, the studio may struggle to prove it owns or can pass on the necessary rights.

A contractor agreement for freelance designer copyright in NZ should cover more than payment and deadlines. It should make the contractor's creative output usable by the studio and deliverable to the client on the agreed terms.

Key clauses include:

• IP assignment: the contractor assigns all project-specific IP to the studio, including drawings, models, renders, specifications, schedules, design concepts and written work.
• Timing of assignment: rights transfer on creation or on payment, depending on the commercial deal. Studios often prefer transfer on creation, with payment handled separately.
• Moral rights consent: the contractor consents to reasonable editing, adaptation, combination with other work and non-attribution where needed for client delivery.
• Confidentiality: the contractor must keep client details, budgets, supplier pricing, unpublished designs and business methods confidential.
• Third-party materials: the contractor must not include unlicensed images, models, fonts, textures or software assets in deliverables.
• Source file delivery: the contractor must provide editable files, passwords, linked assets and project folders in the required format.
• No portfolio use without approval: the contractor cannot publish work before the studio and client have approved any public use.
• Non-solicitation: the contractor should not approach the studio's client or key suppliers outside the project for a reasonable period, where appropriate.

Employment agreements need a different approach. Employees are generally creating work for the employer in the course of their role, but the agreement should still confirm ownership of IP, confidentiality, return of materials and use of company systems. This is especially relevant for senior designers who bring their own methods, client relationships or pre-existing libraries into the business.

Founders should also check ownership inside the company. If two designers set up a studio before incorporating a company, early concepts, brand materials, templates and client proposals may have been created personally by the founders. The company should receive an assignment of that IP, especially if the business may take investment, bring in shareholders or be sold later. The Companies Act 1993 and Companies Office processes help identify the company and its directors, but they do not automatically transfer founders' creative assets to the company.

Trade marks are another part of control. Your studio name, logo or collection name may be registrable through IPONZ if it distinguishes your services. Trade mark registration will not protect each interior concept, but it can protect the brand under which your design services are sold. Keeping your NZBN, company name and trading name consistent also helps clients and suppliers know who they are contracting with.

For contractor-heavy studios, file hygiene is just as important as wording. Store project folders under the studio account, not a freelancer's personal drive. Keep licence records for software assets and stock imagery. Require contractors to delete or return confidential materials at the end of the engagement. These simple steps make the legal terms easier to enforce in day-to-day operations.

Managing Client Expectations, Privacy and Commercial Risk

Clear IP terms work best when they are matched with practical client communication at proposal, approval and handover stages.

Clients are less likely to push back on IP clauses when they understand what they are getting. Instead of saying you do not provide CAD files, explain that the quoted package includes final drawings and schedules for the approved project, while editable files and reuse rights are available by agreement. This keeps the conversation commercial rather than defensive.

Use your proposal to set expectations early. State whether the fee includes concept design, developed design, documentation, procurement, styling, project coordination or post-completion support. Then link each phase to deliverables. A client who pays for a concept package should not assume they are receiving full construction documentation or unlimited rights to replicate the design.

Fair Trading Act 1986 issues can arise if marketing or proposals overstate what the client receives. Avoid claims that a design is exclusive if you intend to reuse similar elements elsewhere. Avoid presenting third-party products or images as your own original creations. Pricing, mark-ups, procurement fees and supplier commissions should be described in a way that is not misleading.

The Consumer Guarantees Act 1993 may also matter when you provide services to consumer clients, such as homeowners. Even for business clients, clear service standards reduce disputes. Be specific about what is included, what depends on third-party suppliers, and what approvals the client must provide. Do not promise outcomes outside your control, such as exact product availability or council approval, and include sensible liability limits.

Privacy should not be overlooked. Interior designers often collect floor plans, access details, photographs of private spaces, family or staff information, budgets and alarm or lockbox details. Under the Privacy Act 2020, businesses handling personal information need to collect, use, store and disclose it appropriately. Your privacy policy and project process should explain how you use photos, who can access them, whether contractors receive them and whether they may be used for marketing.

Supplier lists and procurement records also carry commercial risk. A client may ask for your full source list so they can buy directly. You can decide to provide limited product details needed for installation and maintenance, while keeping supplier contacts, negotiated pricing and internal buying notes confidential. If procurement is part of your revenue model, say so at the proposal stage.

Practical controls can prevent most disputes:

• Label documents as concept, draft, final or issued for construction.
• Use watermarks for unpaid or early-stage work where appropriate.
• Keep approval records for each design phase.
• Separate client-facing schedules from internal supplier databases.
• Confirm in writing when additional reuse rights or source files are requested.
• Do not hand over final files until payment conditions in the contract are met.

Worked example: a boutique studio designs a cafe interior in Wellington. The client pays for concept, documentation and procurement support for one site. Six months later, the client opens a second cafe and asks the builder to copy the first design using the original CAD files. If the contract limited the licence to one premises and excluded source files, the studio has a clear basis to charge for the second site. If the contract said nothing, the dispute becomes harder, more expensive and more personal.

Another example: a freelance designer creates renders for a studio using a mix of original modelling and paid texture packs. The studio sends the renders to the client, who uses them in paid advertising. If the texture licence only allowed internal concept use, everyone may face a rights issue. Contractor terms and asset records help identify and fix these problems early.

FAQs

Who Owns Interior Design Plans in New Zealand?

Ownership depends on the contract, the creator's role and the type of work. Employees usually create work for their employer in the course of employment. Contractors and client commissions need clear written terms because default copyright rules may not match what the studio or client expects.

Does a Client Own the CAD Files if They Paid for the Project?

Not automatically. Payment may give the client rights to use the final deliverables, but editable CAD or design source files should be dealt with separately. Many designers provide PDFs and schedules as standard, with source files available only for an extra fee or limited purpose.

Can a Freelance Interior Designer Reuse a Concept From a Client Project?

A designer may reuse general ideas, skills and know-how, but should be careful with specific drawings, distinctive layouts, confidential client information and paid-for deliverables. The safest position is to state in the contract which unused concepts and background materials the designer can reuse.

Are Mood Boards Protected by Copyright?

Original mood board layouts and written selections may be protected, but many images included in them may belong to suppliers, photographers or stock libraries. A client licence should not promise rights in third-party material that the designer does not control.

What Should a Design Deliverables IP Assignment Cover?

It should cover all project-specific outputs, including concepts, plans, renders, CAD files, schedules, specifications and written materials. It should also address timing of transfer, moral rights consent, confidentiality, third-party content, source file delivery and portfolio use.

Key Takeaways

• Interior design IP ownership in New Zealand should be split between final client deliverables, editable working files, background studio assets and third-party materials.
• Copyright can protect drawings, plans, renders, specifications and some compilations, but it does not protect a broad style or general design idea.
• A strong interior design contract should state whether the client receives an assignment, a licence, or limited rights for one project or premises.
• Studios hiring contractors should use written IP assignments so concepts, CAD files, renders and schedules can be delivered to clients without ownership gaps.
• Supplier lists, pricing notes and procurement databases are often best protected through confidentiality, access controls and clear handover rules.
• Portfolio use, photography, privacy and third-party image licences should be handled before work is published or passed on.
