Document format and locale facts for New Zealand

Why these defaults?

The country code comes from ISO 3166. Unicode CLDR supplies presentation-oriented locale, currency, paper, date, language, calendar, numbering, and direction metadata. Defaults reduce setup time; they do not decide what a valid document must contain.

Document vocabulary and checks

New Zealand GST taxable-supply-information terminology, value-dependent information, buyer-request timing, seven-year sales-and-purchase retention, and paper/electronic record boundary are reviewed. This generator does not transmit a Peppol eInvoice. Special supplies, shared or buyer-created information, corrections, registration status and transaction-specific GST treatment remain separate checks.

• Guidance: Since 1 April 2023, New Zealand uses value- and supply-dependent taxable supply information rather than requiring one tax-invoice form. For supplies over NZ$200, a GST-registered buyer may generally request the information and the seller must provide it within 28 days (or another agreed date). Show the seller's GST number when the applicable information tier requires it.Evidence NZ_IRD_TAXABLE_SUPPLY_INFORMATION, NZ_IRD_TAXABLE_SUPPLY_THRESHOLDS · reviewed 2026-07-19 · review by 2027-01-19 · automation advisory only
• Required when applicable: Keep cash and electronic sales and purchase records, including taxable-supply information and invoices, for seven years. Paper, electronic, or mixed records are accepted when they remain readable and available.Evidence NZ_IRD_RECORD_RETENTION, NZ_IRD_COMPUTER_RECORDS · reviewed 2026-07-19 · review by 2027-01-19 · automation advisory only
• Guidance: New Zealand's taxable-supply-information rules do not require one document format. Electronic records are accepted if they remain retrievable and readable; this generator does not claim to create or route a New Zealand Peppol eInvoice.Evidence NZ_IRD_TAXABLE_SUPPLY_INFORMATION, NZ_IRD_COMPUTER_RECORDS · reviewed 2026-07-19 · review by 2027-01-19 · automation advisory only
