Are E-Signatures Legally Valid in New Zealand?

1

These days almost everything can be done online. Signing documents is no different. But what is sufficient to make an e-signature legally binding?  This article will explore how electronic signatures are recognised under New Zealand law and what you need to make sure is done so you can rely on the signed document. 

The Contract and Commercial Law Act 2017 requires a few key conditions to be met for an e-signature to be valid. Some documents can’t be signed electronically at all.

 

How the law sees e‑signatures

An electronic signature carries the same legal weight as a handwritten one if it is a document that can be e-signed and meets three basic requirements:

  • It reliably identifies the person signing

  • The person has agreed to sign electronically

  • It’s properly linked to the document, so you can tell if it’s been changed after signing

If all three are covered, your e‑signature is valid.

 

What does “reliable” actually mean?

Here, we’re just looking at a situation where you are signing a commercial contract or a key legal document. 

Reliable ways to sign electronically include:

  • A trusted signing platform like DocuSign or Secured Signing

  • An email chain that clearly shows who signed and when

  • A digital system that keeps an audit trail

 

Consent matters

You can’t assume someone is happy to sign electronically. They have to agree to it.

That consent can be given in a few ways:

  • Clicking “I agree” on an online platform
  • Confirming by email that they’re happy to sign electronically
  • Agreeing in advance within the contract itself

If there’s no clear consent, the electronic signature isn’t valid.

 

Keeping the document intact

The signature also needs to be attached to the document in a way that shows whether it’s been altered later.

Most proper signing platforms handle this automatically, they lock the document after signing and create an audit log, but it’s worth being aware of.

 

So, what actually counts as an e‑signature?

It’s broader than most people think. In New Zealand, an electronic signature could be:

  • Typing your name at the end of an email

  • Scanning and emailing a handwritten signature

  • Clicking “I accept” on a website

  • Signing through a secure online platform

As long as it’s reliable, there’s clear consent, and the document’s integrity is protected, it’s valid.

 

But not everything can be signed electronically

Some documents still require pen on paper because they have strict witnessing requirements. For example:

  • Wills

  • Enduring Powers of Attorney

  • Statutory declarations and affidavits

  • Certain property transactions unless they’re completed through an approved Land information New Zealand (LINZ) digital process

For these, the law still requires physical signing and witnessing. You can’t replace it with an electronic option just yet.

 

Why it matters

Electronic signatures are practical and save time. For most everyday agreements, they’re perfectly fine.

But when it comes to important legal documents, especially those with formal witnessing requirements, you’ll still need to sign with pen and paper.

Knowing when an e‑signature is valid (and when it’s not) can save you from unexpected delays or challenges later on. Get in touch.
