eSignature law in New Zealand

Electronic signatures are legally binding in New Zealand under the Contract and Commercial Law Act 2017, which gives electronic signatures the same effect as handwritten ones.

Governing law: Contract and Commercial Law Act 2017 (Part 4), replacing the Electronic Transactions Act 2002 (2002)

New Zealand recognised electronic signatures in the Electronic Transactions Act 2002, now consolidated into Part 4 of the Contract and Commercial Law Act 2017. A legal requirement for a signature is met by an electronic signature where it adequately identifies the signer and indicates their approval of the information, and is as reliable as appropriate given the purpose and circumstances. Consent (which may be inferred from conduct) to using electronic signatures is required. The framework is technology-neutral and does not mandate certificates for ordinary contracts, so a simple electronic signature is valid and widely used for commercial and employment documents. Electronic records are also admissible as evidence under the Evidence Act 2006.
