Are electronic signatures legally valid for subcontractor agreements and variations in New Zealand?

Yes, in most cases. Part 4 of the Contract and Commercial Law Act 2017 lets a legal requirement for a signature be met electronically when the signature identifies the signer, shows their approval and is reliable enough for the purpose. A small number of documents are excluded, including wills, affidavits and powers of attorney. Read our guide to e-signature law in New Zealand .

Do subcontractors and site workers need a Flowsign account to sign?

No. Each signer gets an email with a private link, opens it on a phone, tablet or computer and signs in the browser. There is nothing to install and no account to create.

Can a subcontractor sign on site?

Yes. In-person signing lets a site manager hand over a phone or tablet so the subcontractor signs on the spot, and the record is timestamped. Mobile and in-person signing are included on every plan.

Can we send a site induction to a whole crew at once?

Yes. Build the induction as a template, then send one package per person from a list. Bulk send is included on the Business and Enterprise plans. Compare plans .

What record do we keep for each job?

Every completed package is sealed into a tamper-evident record with an audit trail and a certificate of completion showing who signed, when and from where. Both are included on every plan, including Free. See how we protect documents .

Inductions for the whole crew. Build the site induction and health and safety sign-off as a template, then send one package per worker from a list.
Subbie agreements and variations. Send subcontractor agreements and variations from a template and route them to each party in the order you set.
Signed on site, on any device. Hand over a phone or tablet at the gate, or send a link the crew can sign from the ute. Every signature is timestamped.
One pack per job. Bundle the subcontractor agreement, induction and health and safety sign-off into one package, so each subbie gets a single link.
Reminders that do the chasing. Automatic reminders follow up anyone who has not signed, so the site manager is not phoning around. Included on the Solo plan and above.
Paperwork that fits the job. With workflows, a few answers decide which documents go out and who signs next. Included on the Business and Enterprise plans.

Agree the change before the work starts.

Send a variation from a template and the client signs from a link on their phone. The builder countersigns in the order you set, and both get the sealed copy.

See who is cleared for site.

Every induction and agreement sits in one list, showing who has opened, signed or still needs a nudge. Each job keeps its own timestamped record.

How it works. From subbie pack to job file in three steps.

Set up the subcontractor pack

Build the agreement, site induction and health and safety sign-off as a template, with a role for each party who signs.

The template builder with the Setup, Signing fields and Publish steps above a grouped list of the template's documents.

Send it to the crew

Send one package per worker from a list, or hand over a tablet on site. Nobody needs an account to sign.

The Recipients step with delivery set for each role and three rows in the recipients table.

Keep the sealed copy on the job file

Each signed document is sealed as a tamper-evident PDF with a timestamped audit trail, ready to download for the job file.

The Audit trail report listing events with the time, user and event type.

Connect to the systems you already use.

Your systems call the Flowsign REST API, a workflow sends the package, recipients are notified and sign, and webhooks post each event back to your systems and to tools such as Power Automate, Zapier, Make and n8n.
