Contractor Offer Letter (New Zealand)

A contractor offer letter can be legally binding in New Zealand if it satisfies the requirements for a binding contract under the Contract and Commercial Law Act 2017 (CCLA): offer, acceptance, consideration, and an intention to create legal relations. However, an offer letter is typically a preliminary document that summarises the proposed terms of engagement and invites the contractor to accept. Once accepted (in writing or by conduct), it forms a binding contract. For more complex engagements, it is established standards to follow the offer letter with a formal Independent Contractor Agreement that sets out the full terms, including IP ownership, confidentiality, health and safety under the Health and Safety at Work Act 2015, and dispute resolution. The offer letter should make clear whether it is intended to be a binding agreement on its own or merely an invitation to negotiate a formal contract. Under section 6 of the Employment Relations Act 2000 (ERA), it is important that both the written terms and the actual working arrangements reflect a genuine contractor relationship — not an employment relationship — regardless of the label attached.

A contractor offer letter for New Zealand should include several key elements to protect the engaging party (the Principal). First, it should clearly state that the engagement is on an independent contractor basis and not an employment relationship, acknowledging the test under section 6 of the Employment Relations Act 2000. Second, it should identify the services to be performed and the expected outcomes, rather than specifying daily duties in a manner consistent with employment. Third, it should state the fees (inclusive or exclusive of GST) and payment terms, including whether the contractor is registered for GST under the Goods and Services Tax Act 1985. Fourth, it should confirm that the contractor is responsible for their own income tax, ACC levies under the Accident Compensation Act 2001, and any other statutory obligations. Fifth, it should specify the term of the engagement and the notice required to terminate. Sixth, it should address intellectual property ownership under the Copyright Act 1994, which provides that the commissioner of certain works (photographs, films, sound recordings, computer programs) owns the copyright by default — but an express assignment is recommended for all IP created under the engagement. Finally, it should include a confidentiality undertaking and reference the contractor's obligations under the Privacy Act 2020.

Under New Zealand law, there is no statutory requirement for a contractor offer letter to be signed before work commences (unlike an employment agreement, which under section 64A of the Employment Relations Act 2000 must be provided before the employee starts work). However, from a practical and legal risk management perspective, it is strongly advisable to have the contractor sign and return the offer letter — or a formal contractor agreement — before commencing any work. If the contractor starts work without a signed agreement, a contract may still be formed by conduct under the Contract and Commercial Law Act 2017, but the terms may be uncertain or disputed. Inland Revenue and the Labour Inspectorate have the power to investigate the true nature of contractor relationships, and a signed written agreement is the strongest evidence that the parties intended a genuine contractor arrangement. Failing to document the engagement in writing before work commences also creates risk around IP ownership, confidentiality obligations, and payment terms.

Goods and Services Tax (GST) under the Goods and Services Tax Act 1985 is a key consideration in any New Zealand contractor engagement. Contractors whose GST turnover from taxable supplies exceeds or is expected to exceed NZD $60,000 in a 12-month period must register for GST and charge GST at 15% on their fees. The contractor offer letter should clearly state whether the quoted fee is inclusive or exclusive of GST, to avoid disputes about the total amount payable. If the contractor is GST-registered, the letter should require them to issue a valid tax invoice before GST is payable. The Principal (engaging party) may be able to claim an input tax credit on the GST component of fees paid, provided the Principal is also GST-registered and the services are used in the course of a taxable activity. If the contractor is not GST-registered (i.e., their turnover is below the $60,000 threshold), they must not charge GST. The GST registration status of the contractor should be confirmed before the offer letter is issued.

A Contractor Offer Letter (New Zealand) does not legally require a lawyer in New Zealand, and individuals and businesses may draft and execute the document independently. The Employment Relations Act 2000 does not mandate legal representation for the creation or signing of this type of document. However, seeking independent legal advice from a qualified New Zealand lawyer is recommended for transactions involving substantial financial value, complex regulatory requirements, or cross-border elements where multiple legal jurisdictions may apply. A lawyer can verify that the document complies with all applicable statutory requirements, identify potential risks specific to the transaction, and confirm that the terms adequately protect the interests of all parties involved. The High Court of New Zealand has jurisdiction over disputes arising from this type of document, and Companies Office may impose additional compliance obligations depending on the nature of the underlying transaction. Professional legal review is particularly advisable where the document will be submitted to government agencies or used as evidence in legal proceedings.
