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.

Regional or industry-specific closures may add further non-working days for narrower contract definitions; layer them into the calculator's Advanced options if needed.
How does Mondayisation work under the Holidays Act 2003?
The 2014 amendment to the Holidays Act 2003 introduced Mondayisation for six public holidays: New Year's Day, Day after New Year's Day, Waitangi Day, ANZAC Day, Christmas Day, and Boxing Day. When any of these falls on a Saturday or Sunday, the observed holiday transfers to the following Monday (or Tuesday if Monday is already a public holiday). Good Friday, Easter Monday, the Sovereign's Birthday, Matariki, and Labour Day are always fixed on a specific weekday and are not Mondayised.
How is Matariki dated and why is it different from the other holidays?
Matariki was added as a public holiday by the Te Pire mō te Hararei Tūmatanui o te Kāhui o Matariki / Te Kāhui o Matariki Public Holiday Act 2022. The date varies each year and is set by the Matariki Advisory Group based on the rising of the Pleiades star cluster in the pre-dawn sky and the lunar cycle. Dates fall on a Friday between mid-June and mid-July. The 2024-2029 dates are 28 June 2024, 20 June 2025, 10 July 2026, 25 June 2027, 14 June 2028, and 6 July 2029.
Why does the business-day count vary year to year?
Two things shift the monthly count for New Zealand. First, the day of the week the first of the month lands on changes the count of each weekday. Second, New Zealand public holidays anchored to a fixed date shift their weekday across years. Some years a fixed-date holiday lands on a weekend; some countries shift the observance to an adjacent weekday and some absorb it into the weekend. June 2027 also had 20 working days, so the working capacity is unchanged year over year.
