Employment Offer Letter — Independent Contractor (New Zealand)

An employee offer letter in New Zealand is a precursor to a written Individual Employment Agreement (IEA) required under section 65 of the Employment Relations Act 2000 (ERA). It summarises the key terms of the proposed employment, including job title, salary, hours, leave entitlements under the Holidays Act 2003, KiwiSaver contributions under the KiwiSaver Act 2006, and the 90-day trial period option under section 67A of the ERA. In contrast, a contractor offer letter is used when engaging a person as an independent contractor rather than an employee. The contractor is not entitled to employment entitlements (annual leave, sick leave, minimum wage, KiwiSaver, etc.). The contractor offer letter must reflect the genuine characteristics of a contractor relationship: the contractor controls their own work methods, hours, and location; they provide their own tools and equipment; they bear their own business risk; they invoice for results; and they pay their own income tax, GST (if registered), and ACC levies. The distinction is critical because section 6 of the ERA requires the courts and Employment Relations Authority to examine the real nature of the relationship — not just the label. Misclassifying an employee as a contractor can result in significant financial liability for the engaging party.

A signed contractor offer letter can be a binding contract in New Zealand under the Contract and Commercial Law Act 2017 if it contains all the essential terms of the engagement: the identity of the parties, the services to be provided, the fee, the term, and any other agreed terms. However, offer letters are typically brief documents and may not adequately address all the legal issues that arise in a New Zealand contractor engagement — particularly IP ownership under the Copyright Act 1994, confidentiality, health and safety obligations under the Health and Safety at Work Act 2015, Privacy Act 2020 compliance, withholding tax under the Income Tax Act 2007, and dispute resolution. For longer-term or more complex engagements, it is established standards to follow the offer letter with a formal Independent Contractor Agreement. The offer letter should either incorporate the agreement by reference or make clear that it is intended to be replaced by a formal agreement. In either case, it is strongly recommended that the letter is signed before work commences.

Under the Accident Compensation Act 2001, genuine independent contractors in New Zealand are self-employed persons and are responsible for paying their own ACC levies directly to the Accident Compensation Corporation. ACC provides universal no-fault personal injury cover to all New Zealand residents, including self-employed contractors. Self-employed contractors pay two main ACC levies: the Work levy (based on their industry classification and the risk associated with their work activity, as determined by the ACC WorkLevy rate schedule) and the Working Safer levy (a flat levy that contributes to WorkSafe New Zealand). The earner levy (which employees also pay) is also applicable to self-employed persons. The Principal (engaging party) is not required to pay ACC levies on behalf of a genuine independent contractor. However, if the arrangement is later found to be an employment relationship under section 6 of the ERA, the Principal may be liable for unpaid employer ACC levies, along with other employment entitlements such as KiwiSaver contributions, holiday pay, and minimum wage.

Yes, a contractor offer letter or contractor agreement in New Zealand can include a post-engagement restraint of trade clause. However, New Zealand courts apply a reasonableness test to restraint of trade clauses: the restraint must be reasonable in scope, duration, and geographic area, and must protect a legitimate proprietary interest of the Principal (such as confidential information, client relationships, or goodwill). Courts will not enforce restraints that go beyond what is reasonably necessary to protect the Principal's legitimate interests. Restraints in contractor agreements are assessed under the same common law principles as those in employment agreements, with reference to the Contract and Commercial Law Act 2017. Courts may read down or modify an unreasonable restraint to make it enforceable. The restraint should be clearly drafted, specifying the activities restricted, the geographic area covered, and the duration (typically 3 to 12 months for contractor relationships, depending on the nature of the engagement and the legitimate interest being protected). A restraint that is too broad or extends for too long is likely to be unenforceable.

A Employment Offer Letter — Independent Contractor (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.
