A Dual Software License agreement is a sophisticated legal instrument that allows you to distribute your software under two different licensing models simultaneously. Under New Zealand law, this arrangement enables you to offer your software both as a commercial product with traditional licensing terms and as an open-source project with community-friendly conditions. This dual approach provides you with the flexibility to monetize your intellectual property while building an engaged developer community around your software.

When do you need this document?

You need a Dual Software License when you're developing software that could benefit from both commercial sales and open-source community contributions. This is particularly relevant if you're a technology startup looking to establish market presence through open-source adoption while generating revenue from enterprise customers who require commercial support and warranties. Software companies often use this approach when they want to accelerate product development through community contributions while maintaining control over commercial distribution channels. You'll also need this agreement if you're transitioning from a single licensing model to a dual approach, or if you're acquiring software assets and want to implement a hybrid licensing strategy.

Key legal considerations

The primary legal consideration is ensuring clear separation between your commercial and open-source license terms to avoid conflicts or ambiguities. Under New Zealand's Copyright Act 1994, you must carefully define the scope of rights granted under each license type, including usage restrictions, modification rights, and redistribution conditions. Your agreement must address intellectual property ownership, particularly regarding community contributions to the open-source version and how these relate to your commercial offering. Consider liability limitations and warranty provisions, as these typically differ significantly between commercial and open-source licenses. You should also include clear termination clauses and specify how disputes will be resolved, particularly when dealing with international users who may be subject to different legal frameworks.

Legal requirements in New Zealand

In New Zealand, your Dual Software License must comply with the Contract and Commercial Law Act 2017, which governs the formation and enforcement of contracts, including electronic agreements. The Fair Trading Act 1986 requires that your licensing terms avoid misleading or deceptive conduct, particularly when describing the differences between commercial and open-source versions. If your software processes personal data, you must ensure compliance with the Privacy Act 2020 in both license versions. The Consumer Guarantees Act 1993 may apply to consumer transactions under your commercial license, requiring statutory guarantees for software quality and fitness for purpose. Additionally, the Commerce Act 1986 prohibits anti-competitive behavior, so your dual licensing strategy must not create unfair market advantages or restrict competition unreasonably. Ensure your agreement includes proper governing law clauses specifying New Zealand jurisdiction and consider how international users will be bound by these terms.
