E-invoicing for New Zealand — from MBIE Peppol to KiwiSaver.
Kiwi invoicing sits across three regimes: the MBIE-led Peppol BIS Billing 3.0 framework, the bi-monthly GST cycle through myIR, and the payday filing machinery that runs every pay event for KiwiSaver and PAYE. This centre consolidates eight guides — anchored to IRD, MBIE, Companies Office and NZBN register practice — on Peppol BIS, NZBN, Xero/MYOB NZ migration, GST at 15%, IRD real-time GST, KiwiSaver employer contributions, Trans-Tasman invoicing with Australia, and Companies Office filing.
