Are electronic signatures legal in New Zealand?
Yes. Part 4 of the Contract and Commercial Law Act 2017 lets an electronic signature meet a legal requirement for a signature if it adequately identifies the signer, shows their approval and is as reliable as the situation calls for. Schedule 5 takes wills, affidavits, statutory declarations and powers of attorney out of the regime.

- In effect since
- 2017
- Framework
- Part 4, subpart 3 of the CCLA (successor to the Electronic Transactions Act 2002)
- Doesn't cover
- Affidavits, statutory declarations and documents on oath, unless court rules allow (Schedule 5)
- Wills, codicils and other testamentary instruments (Schedule 5)
- Powers of attorney and enduring powers of attorney (Schedule 5)
What section 226 requires
The Contract and Commercial Law Act 2017 (CCLA) replaced the Electronic Transactions Act 2002 and kept its approach. Under section 226, a legal requirement for a signature (other than a witness's) is met by an electronic signature that:
- adequately identifies the signatory and adequately indicates their approval of the information it relates to; and
- is as reliable as is appropriate given the purpose and circumstances of the signature.
Where the signature relates to information the law requires to be given to someone, it counts only if that person consents to receiving an electronic signature. Section 227 lets a witness sign electronically too, provided the signature being witnessed itself complies with section 226.
When reliability is presumed
Section 228 presumes an electronic signature is reliable enough when the means of creating it is linked to the signatory and no one else, was under the signatory's control and no one else's, and any change to the signature after signing is detectable (plus, where integrity matters, any change to the information). That's close to the EU's definition of an advanced signature. A signature that doesn't meet the presumption can still be shown to be reliable on the evidence.
Land Information New Zealand's view
LINZ says a signature image pasted into a document, or one drawn on a touch screen, can't be presumed reliable under section 228 and shouldn't be relied on by itself. Its guidance accepts electronically signed authority and instruction forms for e-dealing, but paper lodgements still need original wet signatures.
Schedule 5 exclusions
- Affidavits, statutory declarations and other documents given on oath or affirmation, except where court rules or guidelines provide for electronic technology.
- Wills, codicils and other testamentary instruments.
- Powers of attorney and enduring powers of attorney, which LINZ says need original wet signatures.
Where SignMaster fits
SignMaster records the evidence section 228 looks for. Each signer gets a unique email link, can be asked for an access code, and agrees to sign electronically before signing, and the certificate of completion logs their email, IP address and timestamps. The finished PDF carries a SHA-256 fingerprint, so a later change to the document shows up. It's a simple electronic signature, suited to quotes, service agreements and supplier terms, but not to Schedule 5 documents.
Questions? Answers.
Is a typed or drawn signature valid in New Zealand?
It can satisfy section 226 if it identifies you, shows approval and is reliable enough for the purpose. A bare image doesn't get the section 228 presumption, so pair it with a process that records who signed and when.
Can a witness sign electronically in New Zealand?
Yes. Section 227 allows a witness's electronic signature, as long as the signature being witnessed also complies with section 226 and the document isn't excluded by Schedule 5.
Can I e-sign a power of attorney in New Zealand?
No. Powers of attorney and enduring powers of attorney fall under Schedule 5, and LINZ treats them as needing original wet signatures.
