New Zealand e-Invoicing Guide

New Zealand has no e-invoicing mandate in tax law, and Inland Revenue receives no invoice data. The obligation that does exist is a procurement one. Rule 44 of the Government Procurement Rules requires mandated agencies to be eInvoice capable, and it took effect on 1 January 2026. Everything outside the government supply chain, B2B and B2C alike, is voluntary. The Ministry of Business, Innovation and Employment has been the New Zealand Peppol Authority since October 2019 and runs adoption as a programme rather than an enforcement exercise.

Rule 44 works off invoice volume. An agency that receives more than 2,000 domestic trade invoices a year must be able to receive eInvoices through its primary accounts payable systems, and one that sends more than 2,000 must be able to send them through accounts receivable. Rule 36 supplies the incentive that matters to suppliers: agencies must pay 95% of domestic trade eInvoices within five business days, against 10 business days for other domestic trade invoices, and report their payment times to MBIE each quarter for publication.

Two claims about New Zealand circulate widely and both are wrong. The first is that B2G eInvoicing has been mandatory since March 2022. No Procurement Rule existed then. What existed was a government commitment, described by MBIE in February 2022 as half of central government agencies being receive capable by the end of that March, with the rest to follow. The rule itself arrived in November 2024 and applied from 1 January 2026. The second is that suppliers earning more than NZD 33 million must send eInvoices to government from January 2027. The duty falls on agencies, not suppliers, and MBIE is explicit that the date is not a hard cut-off .

The framework is trans-Tasman by design. New Zealand and Australia signed an eInvoicing arrangement in October 2018, and on 22 February 2019 the two Prime Ministers, meeting business leaders in Auckland, established the Australia New Zealand Electronic Invoicing Board and confirmed an in-principle decision on Peppol . MBIE became a Peppol Authority that October. Adoption then ran on encouragement for several years, with the February 2022 commitment putting central government agencies on the network and, on 1 April 2023, Inland Revenue replacing prescriptive tax invoices with taxable supply information so that GST returns could be supported by ordinary business records.

The regulatory turn came on 5 November 2024, when Ministers announced a rewrite of Rule 51 of the Procurement Rules . That extended eInvoicing to agencies such as ACC, Waka Kotahi, Health NZ and NZ Police, set January 2026 as the capability date, and required around 135 agencies to pay 90% of domestic trade invoices within 10 business days from 1 January 2025, rising to 95% a year later. The fifth edition of the Rules went live on 9 October 2025 with effect from 1 December, renumbering the rule to 44 and adding both the 2027 large-supplier duty and a requirement that suppliers pay their subcontractors on terms no less favourable than they receive themselves.

Adoption has since outrun the mandate. MBIE reported on 8 July 2026 that registrations had more than doubled in a year to over 110,000 businesses , with close to a million eInvoices exchanged against 260,000 twelve months earlier, putting roughly a third of the cloud-accounting market on the network. The Minister for Small Business and Manufacturing put NZIER's estimate of the prize at NZD 800 million a year and noted that agencies had beaten their 10 working day payment target in the preceding quarter, paying 95.9% of more than 1.6 million invoices on time.

The Rules bind mandated and eligible agencies rather than the private sector, and Rule 44 then filters by volume. The two thresholds are separate tests: receiving more than 2,000 domestic trade invoices a year triggers the receive obligation, sending more than 2,000 triggers the send obligation, and an agency can be caught by one without the other. Domestic carries a precise meaning here, being payment in New Zealand dollars for goods or services supplied within New Zealand by an entity that does business in New Zealand.

The 2027 requirement is the part most often misdescribed. Rule 44.2 obliges agencies, and only those over the receiving threshold, to require their large suppliers to submit eInvoices. Large borrows its definition from section 45(b) of the Financial Reporting Act 2013: revenue of the entity and its subsidiaries above NZD 33 million in each of the two preceding accounting periods, measured on the supplier's total revenue rather than on what the agency spends with it. MBIE's guidance to agencies is that 1 January 2027 is not a hard deadline . The requirement is worked in through new contracts, renewals, retenders and significant variations, and is not applied retrospectively to contracts already running. The definition does not reach international suppliers.

Several categories sit outside both rules. Reimbursement of employee expenses, rents and leases, credit card statements, finance payments, insurance premiums and regular contract payments that need no invoice, such as progress payments on a roading contract, are not treated as invoices for these purposes. Payment times do not apply while goods, services or works are unsatisfactory or incomplete, the amount is in dispute, or the invoice is incomplete or incorrectly rendered. Ordinary tax rules continue unchanged: business records must be kept for seven years , in English or Māori unless Inland Revenue approves another language, with offshore or cloud storage needing Inland Revenue approval.

New Zealand runs a four-corner Peppol model with no clearance step and no central government platform. A supplier sends to its Access Point, which passes the invoice across the network to the buyer's Access Point for delivery. MBIE accredits Access Point providers , carries out the due diligence and security checks and monitors their compliance, but sits outside the flow of documents. Businesses are addressed by New Zealand Business Number , which is why an NZBN with its core register fields set to public is a precondition of receiving eInvoices at all.

The document specification is PINT A-NZ , the Australia and New Zealand specialisation of the Peppol International billing process, shared with Australia so that a trans-Tasman invoice needs no translation. The current version is 1.1.2, published on 21 November 2025, with an optional self-billing specification alongside it. The migration off the older A-NZ Peppol BIS 3.0 extension is finished. The two Peppol Authorities set 15 November 2024 as the date PINT A-NZ became mandatory and 15 May 2025 for phasing out the BIS 3.0 extensions , and the extension was deprecated on 22 May 2025 and removed from the Peppol network on 31 March 2026 , with its specification artefacts and schematron files taken down.

Nobody outside the transaction sees the invoice. MBIE states that there is no visibility of eInvoices for government, including Inland Revenue, or for any third party, and that only the sender, the receiver and their two Access Points can read the document. Inland Revenue says the same on its own site . That is the structural difference between the New Zealand model and the clearance and continuous transaction control regimes used across Latin America, southern Europe and much of the Gulf, and it is why adoption here has to be sold on cash flow and admin savings rather than compelled by a tax authority.

There is no financial penalty for failing to adopt eInvoicing in New Zealand, for agencies or for businesses. The obligations live in the Government Procurement Rules rather than in the Tax Administration Act or the Goods and Services Tax Act, so the enforcement mechanism is transparency. Rule 36 requires agencies to report domestic eInvoice and trade invoice payment times to MBIE quarterly, and the results are published: performance data for over 100 agencies was released for the first time in July 2025 , having previously covered only around 30 central agencies.

For suppliers the consequence is contractual and commercial rather than punitive. Agencies apply the 2027 requirement through their procurement and contract management, so a large supplier that cannot send eInvoices meets the requirement at tender or renewal rather than through a fine. The cash-flow gap is the sharper incentive: five business days for 95% of eInvoices against 10 business days for everything else, on documents that cannot be mislaid in an inbox.
