Is an electronic signature legal in New Zealand?
Short answer: Yes. Under section 226 of the Contract and Commercial Law Act 2017, a legal signature requirement is met by an electronic signature that adequately identifies the signer, indicates their approval and is as reliable as appropriate, except for the matters excluded by Schedule 5.
The laws
Contract and Commercial Law Act 2017, Part 4 (electronic transactions)
Re-enacted the Electronic Transactions Act 2002. Section 226 covers signatures, section 227 witnessing, section 228 a presumption of reliability, and section 218 with Schedule 5 sets out exclusions.
The signature rule
Section 226(1) says a legal requirement for a signature (other than a witness's) is met by an electronic signature that adequately identifies the signatory and their approval of the information, and is as reliable as appropriate given the purpose and circumstances.
Where the signature relates to information legally required to be given to someone, that person must consent to receiving an electronic signature (s.226(2)).
Presumption of reliability and witnessing
Section 228 presumes an electronic signature is reliable if the signing method is linked to and controlled only by the signatory, and later alterations to the signature (and, where relevant, the information) are detectable. Section 227 allows witnessing with an electronic signature that meets similar tests.
What is excluded
Schedule 5 Part 3 excludes provisions relating to public notices; information to be given in writing in person or by registered post; notices that must be attached or displayed; affidavits, statutory declarations and documents on oath; powers of attorney and enduring powers of attorney (except those created by deed in connection with a security interest, per s.218(3)); wills and codicils; negotiable instruments; bills of lading; search and entry warrants; and certain Fair Trading Act consumer information. Court and tribunal procedure rules are also excluded unless those rules permit electronic methods.
Practical tips
Outside the Schedule 5 exclusions, section 226 lets most contracts be e-signed. Keep a record of how the signer was identified and their approval shown.
eSignSimple provides simple electronic signatures with an audit trail that records timestamps, IP addresses and a document hash. It does not issue qualified, advanced or certificate-based signatures, so where a law requires one of those you will need a licensed or accredited provider.
