NEW ZEALAND Law and Practice Contributed by: Shane Campbell and Thomas Westaway, Campbell Westaway
1. Dispute Resolution Methods 1.1 Main Dispute Resolution Methods New Zealand’s commercial dispute resolution land- scape is pragmatic and pluralistic. Litigation, arbi- tration, and a range of alternative dispute resolution mechanisms coexist and are frequently used in com- bination. The choice between them is shaped by the nature of the dispute, the parties’ contractual arrange- ments, and the relief sought. Litigation in the High Court remains the primary forum for substantial commercial disputes, offering definitive judicial determination, interim relief, and the devel- opment of binding precedent. New Zealand courts apply the common law principle of precedent, with persuasive authority drawn from other common law jurisdictions. Arbitration is a well-established feature of the com- mercial landscape and supported by statute and New Zealand’s commitment to international obligations such as the New York Convention. Domestically, it is particularly prevalent in construction, property, and infrastructure disputes where parties have agreed in advance to a private binding process. Mediation and negotiation are the principal ADR methods available to commercial parties and are actively encouraged by the courts. For construction disputes, adjudication under the Construction Contracts Act 2002 provides a widely used fast-track statutory mechanism. Tikanga-based dispute resolution, rooted in the con- cept of hohou te rongo and the restoration of rela- tional balance, operates as a distinctly indigenous mechanism alongside common law processes. It is receiving growing formal recognition, including from the Supreme Court and within the Government Centre for Dispute Resolution’s best practice framework. 1.2 Choice of Dispute Resolution Method Litigation remains the most favoured mechanism for resolving complex commercial disputes in New Zea- land, particularly where interim relief is required, a party is unwilling to engage in consensual resolution, or the matter raises novel questions of law. In prac- tice, the boundaries between mechanisms are porous. Sophisticated commercial parties routinely structure
dispute resolution as a sequenced process rather than a binary choice, and recent procedural reforms have embedded that disposition within the court system itself. Arbitration is prevalent in construction, lease, and general commercial contract disputes, reflecting the frequency of pre-dispute arbitration clauses in stand- ard-form contracts and the mechanism’s advantages of privacy and finality. Tiered dispute resolution claus- es are common in commercial contracts. Mediation and negotiation are used across a broad range of commercial disputes and at various stages of proceedings. Negotiation typically represents the first step in any sequenced resolution process. Mediation most commonly occurs after proceedings have been filed but before trial, once the parties have a clearer picture of their respective positions. 1.3 Key Dispute Resolution Trends New Zealand dispute resolution is in a period of sus- tained institutional reform, animated by a broad com- mitment to proportionality, cost-efficiency, and timely resolution. Chronic court delays have accelerated both structural change and the growth of alternatives to litigation. The most consequential response is the High Court (Improved Access to Civil Justice) Amendment Rules 2025, in force from 1 January 2026 (the New Rules). The New Rules introduce an evidence-first model, replace standard discovery with front-loaded initial disclosure obligations, and place the Judicial Issues Conference at the heart of case management. Propor- tionality is embedded as a governing principle, includ- ing promoting ADR at every stage of proceedings. The re-establishment of a dedicated Commercial List at the Auckland High Court from October 2025 reflects the same orientation, providing an expedited case management pathway for disputes valued at NZD1 million or more. The Disputes Tribunal Amendment Act 2025, effective 24 January 2026, increased the Tribunal’s financial jurisdiction from NZD30,000 to NZD60,000.
