New Zealand reporting cycles and business-day rules
New Zealand business-day cycles run against IRD PAYE deposit on the 20th of the following month (small employers with PAYE under NZ$50,000 per annum can file quarterly), GST returns on the 28th of the month after the period, and the provisional tax three-instalment cycle (28 August, 15 January, 7 May) for March year-end taxpayers under the standard ratio option. The Reserve Bank of New Zealand operates ESAS as the wholesale RTGS system on bank business days. Mondayisation under the Holidays Act 2003 applies to six specific public holidays. The Contract and Commercial Law Act 2017 sets default payment timing where contracts are silent.
