With no establishment and no New Zealand tax registration, there is nothing to do – GST runs on periodic returns and there is no real-time reporting. Revisit only if you start supplying the New Zealand government at scale.

The 2027 mandate covers domestic B2G trade invoices in NZD and excludes cross-border transactions, per the sources read – so a GST registration alone shouldn't pull you in. If you tender for New Zealand government work through a local presence, check which side of the line your invoicing sits on.

Below the NZ$33 million threshold there is no mandate – e-invoicing stays voluntary for B2B and B2C. If you supply government, though, connecting to Peppol through an accredited access point (using your NZBN) puts you on the 95%-paid-within-five-business-days track. Keep records for at least seven years either way.

If your revenue tops NZ$33 million in each of the two preceding accounting periods and you invoice government, your domestic B2G trade invoices must go through Peppol (PINT A-NZ) from 1 January 2027, per the sources read. Purely private-sector business carries no duty – B2B e-invoicing stays voluntary – but agencies pay valid e-invoices within five business days, which is its own argument for connecting.
