This chapter examines the choice of law rules that determine the law applicable to international contracts in New Zealand, comparing them to the Hague Principles. Private international law in New Zealand is still largely a common law subject, and the choice of law rules on international commercial contracts are no exception. The general position, which has been inherited from English common law, is that parties may choose the law applicable to their contract, and that the law with the closest and most real connection applies in the absence of choice. There are currently no plans in New Zealand for legislative reform, so the task of interpreting and developing the choice of law rules continues to fall to the courts. When performing this task, New Zealand courts have traditionally turned to English case law for assistance. But they may be willing, in future, to widen their scope of inquiry, given that the English rules have long since been Europeanized. It is conceivable, in this context, that the Hague Principles may be treated as a source of persuasive authority, provided they are consistent with the general principles or policies underlying the New Zealand rules.
